45-55%) while felsic is the one with a greater silica content (approx.70-90%). Mafic customers use basalt products to save weight, improve performance, and remain cost competitive. Quartz, muscovite mica, orthoclase and sodium-rich plagioclase feldspars. The difference in the level of silica present in the two arises from the origin of the two rocks. This is per the fact that these lavas erupt at a high temperature. mafic. The difference between Mafic and Felsic rocks are the silica content present. The bases of … Calculating the percent difference between two given values is quite an easy task. What is the approximate silica content of a granite? Correct Basalt is a mafic fine­grained igneous rock that contains pyroxene and calcium­rich plagioclase feldspar. Intrusive rocks also can be categorized consistent with the shape and size of the intrusive body and its relation t… Felsic rocks, in general, form the bulk of the continental plates, while mafic basalt forms the seafloor. Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite. A few years ago we as a company were searching for various terms and wanted to know the differences between them. Olivine, amphibole, pyroxine, and biotite. 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. To set some ground rules: All of these are igneous rocks. It has a higher composition of silica, aluminum, potassium, sodium, and calcium. We hope you are enjoying ScienceStruck! Mafic lava creates basalt while felsic lava produces andesitic and rhyolite rocks. Felsic magma or lava is higher in viscosity than mafic magma/lava. They are mostly found in specific geographic areas known as convergent zones, where the geologic plates collide. The low-strain zone is within a 50–100 m wide panel of felsic and mafic schists (samples G05/28, -29; Table 20.1) that can be followed north–south for >1 km. Whereas, felsic rocks are rich in silica and aluminium along with oxygen, sodium and potassium that gives the light shade for these rocks. The felsic lava is usually found at 650-750˚ C and is can cause explosive volcanic eruptions. We'll assume you're ok with this, but you can opt-out if you wish. Heat would destroy them. Basalt Mafic is an adjective describing a silicate mineral or igneous rock that is rich in magnesium and iron, and is thus a portmanteau of magnesium and ferric. Graphite is a well-known example of felsic rocks. It is commonly erupted as passive lava flows due to its low viscosity (resulting from high magmatic temperatures and low silica contents). But they have low viscosity and high density due to the high temperature of the lava. Felsic is also rich in low-density minerals like oxygen, sodium and potassium. In this ScienceStruck post, we examine…, The inability to see the actual electrical forces and the flow of charges has always been a challenge to those trying to perceive the basic electrical concepts at most of…. The silica level of mafic rocks is 45-55%, which is because they are originated in volcanoes present at the sea bed. Is pumice extrusive or intrusive? Because of these high temperatures, the viscosity is usually low as compared with felsic lava. Composition of Igneous Rock. Mafic’s new Shelby NC location is set to be the largest Basalt Fiber Production Facility in the World Our site includes quite a bit of content, so if you're having an issue finding what you're looking for, go on ahead and use that search feature there! Nevertheless, there are exceptions to this rule; when degassed felsic lava erupts at the surface, it is non-explosive, and some hydro-volcanic eruptions with mafic magma are explosive. Mafic magma is less viscous than felsic magma. Geologists traditionally divide the compositions of the igneous rocks into four major groups or … This is because the lava, while eruption, is at a lower temperature as compared to that of mafic lava. The mafic lava usually has a low viscosity and is running. A mafic rock like basalt generally has tales to tell of life in the mantle, while for a felsic rock like granite, whose progenitors were themselves crustal, the mantle is a nearly forgotten ancestral homeland." The high silica content (70-85%) is because of the geographical location the felsic rocks are found at. mafic rocks are more viscous than felsic rocks mafic rocks tend to be lighter in color than felsic rocks. Mafic and felsic are not commonly used terms, as one may observe. Basalt lava is associated with lowly shield-volcanoes. As iron-rich silicates are normally dark in color, mafic rocks are dark-colored. nadineklein. Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite.Common mafic rocks include basalt, diabase and gabbro.Mafic rocks often also contain calcium-rich varieties of plagioclase feldspar.

Index Igneous rock concepts Reference Lutgens & Tarbuck Ch 3 Bjornerud Ch 2 Thus, these rocks have low density unlike mafic rock, which have high density are heavy. It is of, relating to, or denoting a group of light-colored minerals, including feldspar, feldspathoids, quartz, and muscovite. felsic. Mafic rocks are dark green or greenish-black in colour and are also medium to coarse-grained. It is relating to, denoting, or containing a group of dark-colored, mainly ferromagnetic minerals such as pyroxene and olivine. Mafic magmas are usually produced at spreading centers, and represent material which is newly differentiated from the upper mantle. This is since their origin is mostly the sea bed, that is not abundant in silica. Mafic lavas crystallize to form basalt, which is also dark in color. 5.Either in describing rocks or lava, mafic means that the lava or rock has less silica while felsic implies that the lava or rock has the most silica. Common mafic rocks include basalt and gabbro. Is the mantle mafic or felsic? Igneous Rock (textures) 13 Terms. Well, we're looking for good writers who want to spread the word.

Most of these rocks are gray though Mafic rocks are also found in brown, green, and even black colors. The minerals present in the two is also the reason due to which there is a contrasting difference in their characteristic appearance. The increasing pressure with depth causes the granite to start melting at lower temperatures but causes the basalt MPs to rise. Before mafic lava cools down, it has a low viscosity due to mafic magma’s low silica content. A dominant component of oceanic crust, basalt is the most abundant volcanic rock. Common mafic rocks include basalt, diabase and gabbro. https://www.sciencedirect.com/science/article/pii/S0024493704002014, https://mingtang.me/publications/Tang%20et%20al_Science%202016.pdf, Comparison Table Between Mafic and Felsic, Main Differences Between Mafic and Felsic, Difference Between Lucifer and Satan (With Table), Difference Between Parrot and Macaw (With Table), Difference Between McAfee LiveSafe and Total Protection (With Table), Difference Between HCPCS and CPT (With Table), Difference Between Catholic and Lutheran (With Table), Difference Between Articles of Confederation and Constitution (With Table), Difference Between Verbal and Non-Verbal Communication (With Table), Low viscosity due to the high temperature of lava.

It offers compelling performance, enabling lightweight composites of the future. Common felsic rocks include granite, rhyolite, and dacite. mafic. The word Mafic comes from (ma) for magnesium and (f) for ferrum or the Latin for iron. tennisqueena. Textural terms include: 1. Common mafic rocks include basalt, dolerite, and gabbro. Either in describing rocks or lava, mafic means that the lava or rock has less silica while felsic implies that the lava or rock has the most silica. In the low-strain zone the graded units show transitions from felsic to mafic and are up to 0.5 m thick (Fig. The lavas that are cooled to form these rocks are also different, in terms of their viscosity. This gives these rocks their characteristic dark green or greenish-black colour. Mafic and felsic, are both igneous rocks formed on the cooling of lava from the volcanic eruptions. c. volcanoes lie on continental margins inland of subduction zones. Although, the two are igneous rocks, which are defined by their levels of silica, the difference in the silica content in the two rocks, is its origin. There is a contrasting difference even in the appearance of the two igneous rocks; one being dark shaded and the other having light shade. On the other hand, Felsic has much higher levels of silica. Basalt Fiber is made from natural basalt rock. It is also known to be a mnemonic, combining (fe) for feldspar, (l) for lenad or feldspathoid, and (s) for silica. Mafic rocks are obtained from mostly the sea bed volcanoes whereas felsic rocks are obtained from the cooling of lavas from the convergent zones. This is an order showing increased silica content. That is not explosive or violent. Igneous Rocks. In conclusion, you have seen the most significant points in mafic vs felsic. Felsic magma, on cooling, forms feldspar and quartz. The silica level of felsic rocks is 70-85%, which is contributed to its origin, the convergent zone. The low density of these rocks is due to the low content of silica present in them. BASALT Basalt is an extrusive mafic volcanic rock. felsic vs. mafic 20 Terms. But Felsic is rich in silica and aluminium. Felsic. Copyright © Science Struck & Buzzle.com, Inc. Since igneous rocks are characterised by silica content in them, mafic is the one with less silica content (approx. This website uses cookies to improve your experience while you navigate through the website. Occurrence of igneous rocks can be either intrusive (plutonic) or extrusive (volcanic). The mineral grains in such rocks can generally be recognized with the bare eye. Felsic. Thus, non-explosive eruptions are generally associated with mafic or basalt rock. PHANERITIC TEXTURE - Igneous rocks with large, visible crystals because therock formed slowly in an underground magma chamber. Amperage Vs. Voltage - What is the Difference. “The purpose of Ask Any Difference is to help people know the difference between the two terms of interest. Ever since then, we've been tearing up the trails and immersing ourselves in this wonderful hobby of writing about the differences and comparisons. The most common felsic rock is granite, which represents the purified end product of the earth’s internal differentiation process. Would you like to write for us? Therefore, rocks are divided into ultramafic, mafic, intermediate, and felsic. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous.. Tuff is a relatively soft rock, so it has been used for construction since ancient times. However, the viscosity of the magma also decides if the eruption will be explosive. basalt gabbro diorite granite. (Please note that some geologists with questionable motives switch the order of the magnesium and iron and come up with the term "femag." Porphyritic Granite. We write on the topics: Food, Technology, Business, Pets, Travel, Finance, and Science”. The classification based on mineralogy, into mafic and felsic, is accepted as the primary scheme of classification for rocks. But felsic rocks are light-coloured and have a smooth surface. Mafic rocks usually found in abundance include dolerite, gabbro, and basalt. Difference Between Mafic and Felsic: Conclusion. So, what is it?eval(ez_write_tag([[468,60],'askanydifference_com-box-3','ezslot_6',148,'0','0'])); Igneous rocks on chemical analysis were found to be abundant in silicate oxides and therefore it was decided that these igneous rocks would be differentiated based on their silica content. The bubbles frozen in the rocks are called vesicles. It is also known to be a mnemonic, combining (fe) for feldspar, (l) for lenad or feldspathoid, and (s) for silica. Felsic is the term used for the rocks rich in the mental feldspar, that contains aluminium and silica at high levels. This is the site where we share everything we've learned. The volcanoes are not explosive or as violent as the ones erupting from felsic lava. Mafic rocks are darker in color than felsic rocks. ANSWER: Correct Correct! On the other hand, Felsic has much higher levels of silica. It is mandatory to procure user consent prior to running these cookies on your website. Volcanic rocks are the primary formations studied in order to reveal new geological facts. Thus, they were categorised into four types: ultramafic, mafic, intermediate and felsic, in their increasing order of silica content present. The mafic lava is usually at 950 and often leads to a weak volcanic eruption. Mafic rocks are generally found in dark shades of green or greenish-black in colour. They are also contrastingly different in colour: Mafic being dark shades of green while Felsic is usually lightly shaded rocks. Approximately, 70-85%. Hint 1. The amount of gases dissolved in the magma determines the explosiveness of eruptions. Porphyritic Andesite. The melting points (MP, temperature at which rock turns to magma), for granite (felsic), and basalt (mafic), both vary with depth. Mafic magmas are usually produced at spreading centers, and represent material which is newly differentiated from the upper mantle. Mafic rocks are rich in the heavy minerals, iron and magnesium. For a quick summary, the disparity between them is obvious in their levels of viscosity. Felsic refers to silicate minerals, magma, and rocks which are enriched in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. Ask Any Difference is a website that is owned and operated by Indragni Solutions. 2. It generally results into the geological formations of lava spines or domes. Learn more about the Mafic vs. Felsic geological classification through this ScienceStruck article. The low density and light-weight, ascribable to the presence of light-weight minerals such as oxygen, sodium and potassium. This, in turn, would lead to rapid explosive ejection of the gas bubbles. As water, along with other volatile matter, easily and gradually escapes from mafic lava, volcanic eruptions composed of mafic lava explode less violently compared to some lava of different compositions. 3. Mafic and felsic are the terms used to describe the silica content of igneous rocks formed on the cooling of lava. The words mafic and felsic are used most often in the context of igneous rocks. Difference Between Mafic and Felsic (With Table). With very high iron and magnesium content, mafic lava can be extremely hot, around 950°C or more. felsic: glass (may contain a few minerals typical of felsic rocks) pumice: mafic: glass (may contain a few mineral typical of mafic rocks) scoria: Note: Basalt with fewer holes, known as vesicles, is called vesicular basalt. But opting out of some of these cookies may have an effect on your browsing experience. Granite and rhyolite are considered felsic, while basalt and gabbro are mafic (click here for more information on mafic and felsic). APHANITIC TEXTURE - Igneous rocks that form on the earth's surface havevery fine-grained texture because the crystals are too small to see withoutmagnification. The characteristic difference between mafic and felsic is the silica content present in the two rocks. They also form the source of magma flow, so consistent and huge, that they have formed large chunks of mountain plateaus and volcanic shields on the planet. Graphite is found to have 70% of silica. The mafic lava usually has a low viscosity and is running. The process of bubble formation is known as vesiculation. 1. determine texture: coarse-grained (visible crystals) = plutonic, fine-grained (microscopic crystals), or porphyritic (visible crystals in fine groundmass) = volcanic. d. mafic magma mixes with felsic material. 5. Crystalline and amorphous are two basic sub-types of solids, which may look similar on the outside, but are actually vastly different from the inside. When these gases are released, bubbles are formed. Ask Any Difference >> Science >> Difference Between Mafic and Felsic (With Table). Igneous rocks consist of primarily 12 types of oxides. This rock would have a relatively high silica content. Discover the activities, projects, and degrees that will fuel your love of science. The classification is done based on their silica content, as silica is usually the most abundant of all the oxides present. Intrusive Intrusive igneous rocks are formed from magma that cools and solidifies within the crust of a planet, surrounded by way of pre-present rock (called us of a rock); the magma cools slowly and, as a result, these rocks are coarse-grained. Vesicular Basalt. Sometimes, they are also used to differentiate the characteristics of the lava (or magma). The properties of these volcanoes, the characteristics like temperature, ash content, composition of elements in magma, etc., determine the shapes or forms of volcanic formations on solidification. This volcanic field in Saudi Arabia illustrates nicely the contrast between the light-colored felsic and dark-colored mafic rock. 20.6b). Unlike basalt, obsidian's dark color is due to high amounts of impurities rather than the presence of dark colored minerals. This website uses cookies to improve your experience. Porphyritic Basalt. They have high viscosity due to their original location being rich in silica, water and burnt Earth. This category only includes cookies that ensures basic functionalities and security features of the website. Obsidian is commonly a translucent dark brown or black. Classification of rocks, minerals, and magma based on the silica content present in them defines them as either mafic or felsic. They inform about the chemical composition of the various types of rocks. Felsic rocks are usually light in color and have specific gravities less than 3. Mafic is the acronym for magnesium and ferric (Latin for Iron) because this igneous rock is rich in these two minerals. Basalt, with low-viscosity magma, provides an easy escape of the gases to the surface. In simple terms, gabbro is just the cooled magma chamber … It is of, relating to, or denoting a group of light-colored minerals, including feldspar, feldspathoids, quartz, and muscovite. Is Basalt felsic? The temperatures are around 650°C to 750°C. Common mafic rocks include basalt and gabbro. The color of obsidian depends on the chemical composition of … quartz alkali feldspar plagioclase feldspar olivine These cookies do not store any personal information. Intermediate and felsic magmas usually arise where: a. plates diverge as spreading ridges form. Whereas, felsic rocks have high viscosity. Basalt, one of the common examples of Mafic rock has only 50% silica content. Felsic rocks are light in color. Crystalline Vs. Amorphous Solids - What's the Difference? Basalt, one of the common examples of Mafic rock has only 50% silica content. You also have the option to opt-out of these cookies. Which of these minerals is commonly found in both mafic and felsic rocks? A mafic mineral or rock is a silicate mineral or igneous rock rich in magnesium and iron. These rocks are also rich in other minerals like oxygen, potassium and sodium. Igneous rocks 20 Terms. Due to the color of the minerals forming them, the rocks are either light or dark. The location has high levels of silica along with water and burnt earth (due to the magma), thus making the lava sticky. Scoria has more holes … The most common examples of rocks classified as Mafic are gabbro, dolerite, and basalt. The lavas that are cooled to form these rocks are also different, in terms of their viscosity. Due to their origin, the minerals found in the two rocks are also different. These cookies will be stored in your browser only with your consent. Igneous rocks, characterized by their silica content can be put in two categories: mafic and felsic (other two categories being ultramafic and intermediate). 4.Mafic lava creates basalt while felsic lava produces andesitic and rhyolite rocks. This is the main reason for the low density of felsic rocks. Its vesicular structure makes it light enough to float on water. We've learned from on-the-ground experience about these terms specially the product comparisons. Granite and rhyolite are considered felsic, while basalt and gabbro are mafic (click here for more information on mafic and felsic). Most felsic lavas have high viscosity. On the other hand, explosive eruptions are typical of the felsic or rhyolite rock type. While the former is created in high-temperature lava that leads to extremely low viscosity, the latter has a high viscosity.
