What else can I help you with?
Does andesite contain little or no quartz?
Correct. Andesite generally does not have a high enough silica content for quartz to form.
Is andesite intusive?
Andesite is a type of igneous rock that can form both intrusively (inside the Earth's crust) and extrusively (on the Earth's surface). When andesite forms intrusively, it typically cools slowly and can create large crystals.
Is andesite sandstone?
No. Andesite is a volcanic rock.
What minerals form the rocks diorite andesite?
the minerals are olivine and pyroxene ..you're welcome
Is andesite a mineral?
No. Andesite is an extrusive igneous rock.
How old is andesite?
Andesite is not any age in particular. Some deposites of andesite may be hundreds of millions of years old. However, since andesite is volcanic, some andesite rocks may only be minutes old.
Is andesite plutonic?
No. It is volcanic. The plutonic equivalent of andesite is diorite.
Is Andesite an igneous?
Yes. Andesite is an extrusive igneous rock.
Is andesite an extrusive rock?
Yes. Andesite is the extrusive equivalent of diorite
What is the difference between andesite and basalt?
Andesite is an intermediate volcanic rock that contains more silica and is lighter in color compared to basalt. Basalt is a fine-grained volcanic rock that is darker in color and forms from rapidly cooling lava at Earth's surface.
Which extrusive rock has the same composition as andesite?
Dacite is an extrusive rock that has a composition similar to andesite. Both rocks are rich in silica and belong to the intermediate composition category. They form from the volcanic eruption of magma that is intermediate in composition between felsic and mafic.
What minerals form the rocks diorite and andesite?
The minerals that form diorite include plagioclase feldspar, biotite, and hornblende. Andesite is primarily composed of plagioclase feldspar, pyroxene, and hornblende. Both rocks are intermediate in composition between granite and basalt.
