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 andesite nonfoliated?
Andesite is typically classified as an igneous rock, specifically a volcanic rock, and is not categorized as either foliated or nonfoliated since those terms primarily apply to metamorphic rocks. Foliation refers to the alignment of mineral grains under pressure, which is not relevant to andesite. Instead, andesite has a fine-grained texture and can contain a mix of minerals, but it lacks the layered or banded appearance characteristic of foliated rocks.
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.

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 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.
Is obsidian a intrusive or extrusive igneous rock?
Andesite is considered an extrusive igneous rock.
What rock starts with the letter a?
Andesite is a volcanic rock.
