Which extrusive rock has the same composition as andesite?
Dacite is an extrusive rock that has a composition similar to andesite. Both rocks are rich in silica and belong to the intermediate composition category. They form from the volcanic eruption of magma that is intermediate in composition between felsic and mafic.
How can andesite rock be formed?
Andesite rock is formed through the cooling and solidification of magma in the Earth's crust. It typically forms in volcanic settings where magma with intermediate composition (between felsic and mafic) cools relatively slowly, allowing for the formation of fine-grained crystals. This results in a rock with a medium to dark gray color and intermediate mineral composition.
Is monzonite felsic or mafic?
Monzonite is an intermediate 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'.
Definition for andesitic composition?
Andesitic composition refers to a type of igneous rock that is intermediate in composition between basalt and rhyolite. It typically contains minerals such as plagioclase feldspar, amphibole, and pyroxene. Andesitic rocks are commonly found in volcanic arcs and are associated with convergent plate boundaries.
Which extrusive rock has the same composition as andesite?
Dacite is an extrusive rock that has a composition similar to andesite. Both rocks are rich in silica and belong to the intermediate composition category. They form from the volcanic eruption of magma that is intermediate in composition between felsic and mafic.
What is the mineral composition of an intermediate igneous rock?
felsic and something else i do not remember the second one.
What is an andesite?
a dark, fine-grained, brown or grayish volcanic rock that is intermediate in composition between rhyolite and basalt.
Is andesite basic or acid?
Andesite has an intermediate composition between "basic" and "acid."
What is the igneous rock between granite and basalt?
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
How can andesite rock be formed?
Andesite rock is formed through the cooling and solidification of magma in the Earth's crust. It typically forms in volcanic settings where magma with intermediate composition (between felsic and mafic) cools relatively slowly, allowing for the formation of fine-grained crystals. This results in a rock with a medium to dark gray color and intermediate mineral composition.
Is monzonite felsic or mafic?
Monzonite is an intermediate rock.
What are the five minerals commonly found in intermediate rocks?
The five minerals commonly found in intermediate rocks are plagioclase feldspar, amphibole, biotite mica, pyroxene, and quartz. These minerals typically make up the bulk of the rock's composition and can vary in abundance depending on the specific type of intermediate rock.
What rock types does the Cotopaxi volcano have?
The Cotopaxi volcano in Ecuador is primarily composed of andesite and dacite rock types. Andesite is a volcanic rock with an intermediate composition between basalt and rhyolite, while dacite has a similar composition to andesite but with more silica content.
What kind of rock andesite?

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.

What type of lava is considered intermediate composition?
Andesitic lava is considered intermediate in composition. It has moderate silica content and viscosity, resulting in eruptions that produce both effusive and explosive activity.
Definition for andesitic composition?
Andesitic composition refers to a type of igneous rock that is intermediate in composition between basalt and rhyolite. It typically contains minerals such as plagioclase feldspar, amphibole, and pyroxene. Andesitic rocks are commonly found in volcanic arcs and are associated with convergent plate boundaries.
