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. Viscosity determines what the magma will do. Felsic magmas are higher in silica and contain lighter colored minerals such as quartz and orthoclase feldspar. Posted by on-the-rocks at 6:07 PM. Intermediate rocks are composed of the minerals amphibole and feldspar and contain a combination of light and dark minerals. In geology, felsic is an adjective describing igneous rocks that are relatively rich in elements that form feldspar and quartz. Felsic, intermediate and mafic igneous rocks differ in their mineral composition. In a widely accepted silica-content classification scheme, rocks with more than 65 percent silica are called felsic; those with between 55 and 65 percent silica are intermediate; those with between 45 and 55 percent silica are mafic… B. Mafic minerals contain more light-colored, low-density minerals.

The first is felsic comprising a granodiorite–tonalite, a monzogranite and a biotite granite. Mafic lava, before cooling, has a low viscosity, in comparison with felsic lava, due to the lower silica content in mafic magma. The term mafic is derived from magnesium and the Latin word for iron, while felsic is derived from the words feldspar and silicone. When coupled with xenolith data, however, the seismic velocity distributions suggest that the lower continental crust is composed largely of mafic granulites, gabbros, and amphibolites (50–65%), with up to 10% metapelite, and the remainder of intermediate to felsic granulite (Rudnick & Fountain, 1995).

Because they are made of lighter elements, they tend to be more buoyant than mafic rocks, which are rocks high in magnesium and iron, like basalt. Mafic magma is not viscous and will flow easily to the surface. Felsic rocks are light in color and are composed of feldspars and silicates. Ini adalah istilah yang digunakan oleh ahli geologi untuk menerangkan batuan igniti berdasarkan kandungan silika mereka. Mafic și Felsic nu sunt cuvinte comune în limba engleză. Felsic is a generic term meaning enriched in feldspar and silica (and thus generally lower in iron and magnesium). Gabbro is the name given to intrusive mafic rocks, whereas basalt is the name given to extrusive mafic rocks. Istilah ini juga digunakan semasa bercakap tentang ciri-ciri lava.

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. Mafic Rock. Igneous Rocks explained in simple terms with examples.In this video. Mafic rocks include basalt, its intrusive equivalent of gabbro, and a variety of less common rock types with higher or lower contents of Na and K.
