What kind of rock andesite?

Answer 1

Andesite is an extrusive igneous rock.

Answer 2

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'.

Answer 3

Like Basalt it is a type of extrusive lava produced by a volcano. It is dark, fine-grained, brown or greyish with an aphanitic to porphyritic texture and of intermediate composition (ranging from 57 to 63% silicon dioxide (SiO2)) between basalt and dacite.

Answer 4

Andesite is an igneous rock that is typically fine-grained, intermediate in composition between basalt and rhyolite. It contains minerals such as plagioclase feldspar, pyroxene, and amphibole. Andesite is commonly found in volcanic regions associated with subduction zones.

Answer 5

No. Andesite is an intermediate igneous rock, with a composition in between mafic and felsic.

Answer 6

Yes. Andesite is an extrusive igneous rock.

Answer 7

Answer 8

Answer 9

No. Andesite is intermediate.
