In conclusion, you have seen the most significant points in mafic vs felsic. Therefore, rocks are divided into ultramafic, mafic, intermediate, and felsic. Mafic has low levels of silica. • Mafic-Gesteine haben eine dunklere Farbe als Felsic-Gesteine. Minerals that usually form mafic rocks are clinopyroxene and/or orthopyroxene, olivine, biotite, and amphibole. Most of the igneous rocks can be classified as Mafic or Felsic. Sometimes, felsic volcanic rocks contain small amounts (i.e. phenocrysts) of mafic minerals such as pyroxene, hornblende, or a feldspar mineral. Mafic vs Felsic In the concept of mineralogy, or geology in the much broader sense, two terms are commonly used to describe the characteristics of rocks and also lava. Basically, for magma to flow, oxygen bonds have to break. Silica content in Mafic rocks is around 50% by weight. Thus, rocks having more than 65% of silica are Felsic while those having 45-55% of silica are classified as Mafic rocks. Mafic is used for silicate minerals, magmas, and rocks which are relatively high in the heavier elements. 1. As iron-rich silicates are normally dark in color, mafic rocks are dark-colored. Pegmatites are little different from the common igneous rocks in major elements of bulk composition, and they range from felsic to mafic (silica-rich to silica-poor); granitic and syenitic types are most abundant. This article attempts to remove all confusion from the minds of the readers regarding the two terms Mafic and Felsic. In addition, if a felsic rock is found to be metamorphic with no traces of volcanic protolith (i.e. Mafic vs Felsic Mafic und Felsic sind keine gebräuchlichen englischen Wörter. Rocks are split into one of two categories based upon various factors. In geology, felsic is an adjective describing igneous rocks that are relatively rich in elements that form feldspar and quartz. Felsic rocks are composed of minerals such as quartz, orthoclase, muscovite, and feldspars. Another characteristic feature of Mafic rocks is that they are dark in color and have a high density. These are terms that are used by geologists to describe igneous rocks based upon their silica content. A rock is classified as felsic if it is composed of greater than 75% felsic minerals, which are orthoclase, plagioclase, and quartz. For example, granite contains around 70% of silica. Most of the igneous rocks can be classified as Mafic or Felsic. Mafic and Felsic are not common English language words. Igneous Rocks explained in simple terms with examples.In this video.

In geology, mafic is a term which describes an igneous rock or a silicate mineral rich in iron and magnesium. Obsidian is a natural glass - it lacks crystals, and therefore lacks minerals. Viscosity is dependent on molecular bonds, and density is dependent on, well, density. Felsic is a term that is used to refer to igneous rocks rich in mineral feldspar. The term mafic is a combination of the words “magnesium” and “ferric.” The majority of mafic minerals are dark green or greenish black and are medium to coarse-grained. Diese Begriffe werden auch verwendet, wenn über die Eigenschaften von Lava gesprochen wird. For a quick summary, the disparity between them is obvious in their levels of viscosity. Felsic rocks are composed of high levels of magma, silicate materials, and rocks which are also rich in potassium, oxygen, silicon, and sodium. Felsic rocks are mostly light-colored and the most common type is granite. As a result, eruptions of volcanoes made of mafic lavas are less explosively violent than felsic … Intermediate lava has a lower silica content than felsic lava, but not as high magnesium or iron levels as found in mafic lava. The second is intermediate to ultramafic, forming small diorite and gabbro intrusions associated with hornblendites and olivine hornblendites. Somit sind Gesteine mit mehr als 65% Kieselsäure Felsic, während solche mit 45-55% Kieselsäure als Mafic-Gesteine klassifiziert werden. 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. It is a glassy-textured, extrusive igneous rock. Coming from Engineering cum Human Resource Development background, has over 10 years experience in content developmet and management. Many students confuse between the two adjectives Mafic and Felsic. Here’s a lesson in geology discussing mafic and felsic rocks. “Mafic” is a term that describes igneous rocks or silicate material characterized by a rich content of iron and magnesium while felsic rocks are igneous rocks that are rich in light elements such as oxygen, aluminum, silicon, potassium, and sodium. • Mafic-Gesteine sind dichter und schwerer als Felsic-Gesteine. Most of these rocks are gray though Mafic rocks are also found in brown, green, and even black colors. When it comes to chemistry, felsic minerals and rocks are at the opposite end of the elemental spectrum as mafic minerals and rocks are. Mafic vs Felsic Im Begriff Mineralogie oder Geologie werden zwei Begriffe verwendet, um die Eigenschaften von Gesteinen und Lava allgemein zu beschreiben. Basalt, one of the common examples of Mafic rock has only 50% silica content. Start studying felsic vs. mafic. Ini adalah istilah yang digunakan oleh ahli geologi untuk menggambarkan batuan beku berdasarkan kandungan silika mereka. Intermediate rocks are composed of the minerals amphibole and feldspar and contain a combination of light and dark minerals. • Mafic rocks are denser and heavier than Felsic rocks. Dies sind Begriffe, die von Geologen verwendet werden, um magmatische Gesteine basierend auf ihrem Siliciumdioxidgehalt zu beschreiben. Felsic, intermediate and mafic igneous rocks differ in their mineral composition. Felsic rocks are commonly oversaturated and contain free quartz (SiO 2), intermediate rocks contain little or no quartz or feldspathoids (undersaturated minerals), and mafic rocks may contain abundant feldspathoids. Thus, the basic name of a felsic rock is determined by the rock’s texture. Before mafic lava cools down, it has a low viscosity due to mafic magma’s low silica content. • Mafische Felsen sind … It is contrasted with mafic rocks, which are relatively richer in magnesium and iron. The most common examples of rocks classified as Mafic are gabbro, dolerite, and basalt. A phaneritic felsic rock is composed of crystals large enough to be seen with the naked eye. In terms of chemistry, this means that mafic and felsic minerals and rocks are at opposite ends of the elemental spectrum. The term is derived from using the MA from magnesium and the FIC from the Latin word for iron, but mafic magmas also are relatively enriched in calcium and sodium. The lava flow has a medium viscosity as well, and once cooled, the resulting rock is known as Andesite. Mafic vs Felsic Im Begriff der Mineralogie, oder Geologie im viel weiteren Sinne, werden zwei Begriffe häufig verwendet, um die zu beschreiben Eigenschaften von Felsen und auch Lava. What is felsic vs mafic vs ultramafic? This article aims to sift through the rubble and find out how mafic rocks are different from felsic rocks. On the other hand, Felsic has much higher levels of silica. In contrast, felsic rocks are made up of a combination of feldspar and silica and are typically light colored rocks. In such cases, it’s customary for the rock to be named after the phenocryst mineral e.g. Mafic vs Felsic Mafic und Felsic sind keine gebräuchlichen englischen Wörter.
