What else can I help you with?
Is granite mafic?
No, granite is not considered mafic. It is an igneous rock that is classified as felsic due to its high silica content and lower concentration of iron and magnesium minerals compared to mafic rocks like basalt.
What is the igneous rock between granite and basalt?
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
What is alaskite?
A plutonic rock consisting of oligioclase, microcline and quartz with subordinate muscovite and little or no mafic minerals. An alkali granite with no mafic minerals
Which rock has more silica granite or basalt?
Granite has more silica than basalt in it.
Does rhyolite have a more mafic composition than basalt?
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
How does a Granite rock and a Gabbro rock differ from each other?
The counterpart of Granite is Rhyolite,the counterpart of Gabbro is Basalt. Gabbro is mafic(Dark coloured) ,Granite is felsic (light coloured) Granite forms from magma of Granitic composition while Gabbro forms from magma of Basaltic composition.
Name one mafic igneous rock formed when melted rock material cooled near the surface of the earth?
Basalt is a mafic igneous rock formed when melted rock material cools near the surface of the Earth. It is characterized by its dark color and fine-grained texture.
Does the mantle have granite?
No; granite is a felsic rock formed by either melting of contintal crust or extreme differentiation of more mafic magmas. The mantle is predominantly made up of an ultramafic rock known as peridotite.
An example of an igneous rock low in silica is granite?
Granite is actually high in silica, which is why it is considered a felsic igneous rock. An example of an igneous rock low in silica is basalt, which is mafic in composition and contains less silica than granite.
What is the odd one out of granite basalt sandstone?
Sandstone is the odd one out as it is a sedimentary rock, as opposed to granite and basalt which are respectively felsic and mafic igneous rocks.
Do Granite and Gabbro have the same chemical composition?
No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.
Is gabbro a felsic rock?
No, gabbro is not a felsic rock. Gabbro is classified as a mafic rock due to its dark color and high content of iron and magnesium minerals, while felsic rocks are light-colored and have a higher silica content.
