What is the texture of the rock andesite?
The texture of Andesite rock is fine-grained and it Extrusive plus it is an 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 a foliated rock?
No. Foliation is a term that applies to metamorphic rocks. Andesite is igneous.
Is obsidian a intrusive or extrusive igneous rock?
Andesite is considered an extrusive igneous rock.

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.
Distinguish between andesite and diorite using two physical properties of igneous rocks?
Andesite typically has a light to dark gray color with a fine-grained texture, while diorite is usually darker in color with a coarse-grained texture. Additionally, andesite usually contains more silica than diorite, leading to differences in their mineral compositions and overall chemical makeup.
Is andesite sandstone?

Is andesite a mineral?

Andesite is considered an extrusive igneous rock.
What kind of rock andesite?
No. Andesite is classed as an 'intermediate' rock, being halfway in composition between a mafic and felsic rock. Mafic rocks are those that contain alot of ferromagnesian minerals (iron and magnesium) which give mafic rocks their dark colouring. Typical ferromagnesian minerals include olivine and pyroxene. Typical mafic rocks are basalt and gabbro. Felsic rocks, on the other hand, are low in magnesium and iron and are usually light in colour, such as granite and rhyolite. Andesite therefore typically contains a mixture of both felsic and mafic minerals and is classed as 'intermediate'.
