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.
What minerals form the rocks diorite andesite?
the minerals are olivine and pyroxene ..you're welcome
Is andesite sandstone?
No. Andesite is a volcanic 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 a mineral?
No. Andesite is an extrusive igneous rock.
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.
What is the difference between andesite and basalt?
Both andesite and basalt are volcanic rocks. Basalt is denser and generally darker than andesite. It has a lower silica content and more iron and magnesium. It most often forms from pahoehoe or a'a lava flows and occasionally scoria cinders. Andesite forms from more slica-rich material and is often found in the form of ash, pumice, or volcanic bombs. It may also sometimes form block lava flows, which are more viscous that a'a or pahoehoe.
Is andesite an extrusive rock?
Yes. Andesite is the extrusive equivalent of diorite
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.
