What is the difference of andesitic and andesite?
Andesite is a type of extrusive igneous rock with moderate levels of silica. Andesitic is an adjective used to describe volcanic material with the composition of andesite. For example, andesitic lava will cool to form andesite.
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.
Andesite has large crystals surrounded by fine grained minerals. which term describes the texture of andesite?
The texture of andesite, characterized by large crystals set in a fine-grained matrix, is called porphyritic. This texture indicates that the rock underwent two stages of cooling: the larger crystals formed from slow cooling beneath the surface, while the fine-grained minerals crystallized quickly during subsequent rapid cooling. This combination gives andesite its distinctive appearance.
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
Is andesite a foliated rock?
No. Foliation is a term that applies to metamorphic rocks. Andesite is igneous.
What are andesite rocks?
Andesite rocks are Igneous rocks. They are jagged and rough, and come from cooled magma.
How do you determine whether a rock is a rhyolite or an andesite?
The composition of the rock will determine whether it is a rhyolite or an andesite.
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.
