Felsic rocks are mostly light-colored and the most common type is granite. In geology, mafic is a term which describes an igneous rock or a silicate mineral rich in iron and magnesium. Mafic and Felsic are not common English language words. Mafic vs Felsic Im Begriff Mineralogie oder Geologie werden zwei Begriffe verwendet, um die Eigenschaften von Gesteinen und Lava allgemein zu beschreiben. Coming from Engineering cum Human Resource Development background, has over 10 years experience in content developmet and management. Felsic is a term that is used to refer to igneous rocks rich in mineral feldspar. This article aims to sift through the rubble and find out how mafic rocks are different from felsic rocks. In conclusion, you have seen the most significant points in mafic vs felsic. It’s really a rather simply answer. Mafic lava creates basalt while felsic lava produces andesitic and rhyolite rocks. In geology, felsic is an adjective describing igneous rocks that are relatively rich in elements that form feldspar and quartz. The most common examples of rocks classified as Mafic are gabbro, dolerite, and basalt. Die meisten der magmatischen Gesteine können als Mafic oder Felsic klassifiziert werden. Runny or sticky. In addition, if a felsic rock is found to be metamorphic with no traces of volcanic protolith (i.e. Felsic magma has more oxygen, so it flows less. As iron-rich silicates are normally dark in color, mafic rocks are dark-colored. Thus, it is clear that these igneous rocks are rich in magnesium and iron. On April 25, 2017 May 2, 2017 By Michael Davis. Mafic has low levels of silica. Dies sind Begriffe, die von Geologen verwendet werden, um magmatische Gesteine basierend auf ihrem Siliciumdioxidgehalt zu beschreiben. Mafic rocks have between 45 and 55% of silica, whereas felsic rocks have over 65% of silica, the highest of all types. Intermediate lava has a lower silica content than felsic lava, but not as high magnesium or iron levels as found in mafic lava. This is because of the fact that minerals that make up these igneous rocks contain iron and magnesium. Silica content in Mafic rocks is around 50% by weight. Viscosity is dependent on molecular bonds, and density is dependent on, well, density. Mafic vs Felsic Mafic dan Felsic bukan kata-kata bahasa Inggris yang umum. This broad grouping on the basis of mineralogy related to silica content is used in many modern classification schemes. Basalt, one of the common examples of Mafic rock has only 50% silica content. Approximately only 45-55%. 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. • Mafic Felsen sind reich an Eisen und Magnesium, während Felsic Felsen reich an Kieselsäure und Aluminium sind. 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. 5. The Quérigut mafic–felsic rock association comprises two main magma series. Sebagian besar batuan beku dapat diklasifikasikan sebagai Mafic atau Felsic. 1. Mafic vs Felsic Mafic und Felsic sind keine gebräuchlichen englischen Wörter. Most of these rocks are gray though Mafic rocks are also found in brown, green, and even black colors. Felsic refers to silicate minerals, magma, and rocks which are enriched in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. Mafic lava, before cooling, has a low viscosity, in comparison with felsic lava, due to the lower silica content in mafic magma. “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. These are both made up words used to indicate the chemical composition of silicate minerals, magmas, and igneous rocks. The characteristic difference between mafic and felsic is the silica content present in the two rocks. As adjectives the difference between ultramafic and felsic is that ultramafic is (geology) describing igneous rocks that contain magnesium and iron and only a very small amount of silica, such as are found in the earth’s mantle while felsic is (mineralogy) enriched in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. Due to the color of the minerals forming them, the rocks are either light or dark. • Mafic rocks are denser and heavier than Felsic rocks. Rocks are split into one of two categories based upon various factors. Feldspar is a mineral that contains a high percentage of silica and aluminum. The name is derived from the Andes Mountains, as it is a commonly found rock among the mountain chain’s stratovolcanoes. Igneous rocks are formed by the … The first is felsic comprising a granodiorite–tonalite, a monzogranite and a biotite granite. Diese Begriffe werden auch verwendet, wenn über die Eigenschaften von Lava gesprochen wird. Most of the igneous rocks can be classified as Mafic or Felsic. • Mafic-Gesteine haben eine dunklere Farbe als Felsic-Gesteine. The term “mafic” combines the words “magnesium” and “ferric” and are usually dark-colored rocks. Réng oder plakeg. unmetamorphosed rock from which certain metamorphic rocks come from) it may just be called a “felsic schist.”. • Lava made up of Felsic rocks is slow moving and has a higher viscosity than Mafic lava. phenocrysts) of mafic minerals such as pyroxene, hornblende, or a feldspar mineral. In geology, these terms are descriptive of the chemicals that make up igneous rocks, magmas, and silicate minerals. For example, granite contains around 70% of silica. • Mafic-Gesteine sind reich an Eisen und Magnesium, während Felsic-Gesteine reich an Siliciumdioxid und Aluminium sind. 1. Is Obsidian an Aphanitic? When it comes to chemistry, felsic minerals and rocks are at the opposite end of the elemental spectrum as mafic minerals and rocks are.
