What is Andesite texture?
Andesite texture refers to the fine-grained, intermediate volcanic rock composed mainly of plagioclase feldspar and amphibole minerals. It typically exhibits a porphyritic texture, with larger crystals (phenocrysts) embedded in a matrix of smaller crystals (groundmass). This texture is formed by the slow cooling of magma beneath the Earth's surface.
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 obsidian a intrusive or extrusive igneous rock?
Andesite is considered an extrusive igneous rock.
Is andesite a foliated rock?
No. Foliation is a term that applies to metamorphic rocks. Andesite is igneous.
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 is the texture of andesite?
Andesite typically has a fine-grained texture with a mix of various minerals such as plagioclase feldspar and amphibole. It can appear as a dark gray to black rock with speckles of white or light gray minerals.
Is andesite sandstone?
No. Andesite is a volcanic rock.
Is andesite a mineral?
No. Andesite is an extrusive igneous rock.
Is Andesite an igneous?
Yes. Andesite is an extrusive igneous rock.
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 an extrusive rock?
Yes. Andesite is the extrusive equivalent of diorite
What is the hardness of andesite?
Andesite is classified as an extrusive rock and the name of this rock is South American in origin. However, the hardness of this rock is not listed.
