Is andesite a mineral?
No. Andesite is an extrusive igneous rock.
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.
Where does andesite form?
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
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 .
Why do andesite have small crystals?
Andesite is an Igneous Rock. It has small crystals because it cooled quickly d;D
What igneous rock starts with the letter a?
Andesite is a volcanic rock.
What describes an andesite?
Andesite are fine-grainedextrusive, igneous volcanic rock composed essentially of plagioclase feldspar and one or more mafic minerals, such as hornblende, pyroxene or biotite.(Refer to Geology.com -Igneous Rocks)
Does Andesite contain CaCO3?
No. Calcium carbonate is found in sedimentary and metamorphic rocks. Igneous rocks such as andesite are composed almost entirely of silicates.
What is andesite?
Andesite is a type of igneous rock that is typically light to dark gray in color. It forms when magma from the Earth's mantle solidifies and cools relatively quickly. Andesite is commonly found in volcanic regions such as the Andes Mountains in South America.
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'.
What is the main difference between andesite and diorite?
Both are igneous rocks of intermediate coposition.
