felsic and something else i do not remember the second one.
andesitic composition
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
Olivene is a mineral, not a rock. It can be found in both intrusive and extrusive igneous rocks. The appearance of olivene is mainly controlled by the composition of the magma
Cobalt is a mineral, not a rock.
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.
No. First of all, the terms mafic and felsic generally only apply to igneous rock. even among igneous rocks, mafic and felsic are just ranges on a "spectrum" of composition. Other classifications and examples include ultramafic (peridotite), intermediate (andesite), and intermediate-felsic (dacite).
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
Andesitic igneous rock.
Andesite is an extrusive igneous rock of intermediate composition. This is a volcanic rock that can be found in areas with volcanoes such as, Slovakia.
It tells us if the rock is Mafic (dark) composed mostly of magnesium and ferrum Or Felsic, (light) composed mostly of silicates such as quartz and feldspbar, or intermediate, a mixture of the two.
Both rocks are igneous rock but basalt is an aphanitic igneous rock while granite is a common type of felsic intrusive igneous rock.
a dark, fine-grained, brown or grayish volcanic rock that is intermediate in composition between rhyolite and basalt.
An igneous rock is formed through the solidification of molten material, either magma or lava, that cools and crystallizes. This process occurs below or on the Earth's surface. The mineral composition and texture of igneous rocks vary depending on factors such as the cooling rate and the composition of the molten material.
You say it as ' Igneous ROCK ' and ask whether it is a rock..
The mineral composition of the magma and the rate at which it cools determines what rock forms.
Quartz is a rock-forming mineral--and can be found in all three rock types. There is no igneous rock formation that is exclusively composed of the mineral quartz.
Andesite and diorite are considered intermediate.
No -- it's a type of rock, often a composite. Primay types are igneous (made by fire -- vulcanism), sedimentary (sea beds) and composite (a mixture of other types). In almost every case, all of these types are defined as how the substance at hand was created and in most cases they are not pure minerals.
