Which minerals can be found in all samples of rhyolite and andesite?
Both rhyolite and andesite typically contain the minerals quartz, feldspar (particularly plagioclase and alkali feldspar), and biotite. They may also contain other minerals such as hornblende or pyroxene, though these are more variable. The presence of these minerals contributes to their characteristic compositions and textures. Rhyolite is generally more silica-rich than andesite, resulting in differences in mineral proportions.
What minerals form the rocks diorite andesite?
the minerals are olivine and pyroxene ..you're welcome
What minerals form the rocks diorite and andesite?
The minerals that form diorite include plagioclase feldspar, biotite, and hornblende. Andesite is primarily composed of plagioclase feldspar, pyroxene, and hornblende. Both rocks are intermediate in composition between granite and basalt.
What kind of rocks and minerals are found in volcanoes?
Volcanoes contain a variety of rocks and minerals such as basalt, andesite, rhyolite, obsidian, pumice, and granite. Volcanic rocks are typically rich in silicate minerals like quartz, feldspar, and olivine, with varying amounts of volcanic glass and pyroclastic material. Minerals like sulfur, pyrite, and magnetite can also be found in volcanic environments.
Which type of volcanic material appear grey or pink?
Andesite is a type of volcanic material that can appear grey or pink due to its mineral composition. Grey andesite contains a higher amount of mafic minerals like plagioclase and pyroxene, while pink andesite contains a greater proportion of felsic minerals like potassium feldspar.
Identify three minerals that are normally found with quartz in samples of andesite rock?
Three minerals commonly found with quartz in andesite rock are feldspar (specifically plagioclase), biotite mica, and amphibole (such as hornblende). These minerals are all typically present in andesite as part of the overall composition of the rock.

What minerals make up batholith?
Mainly batholiths in north america are composed primarily of Granite. Also basalt and andesite are also found in batholiths
Which rock has an intermediate composition?
Andesite is a rock with an intermediate composition. It contains minerals such as plagioclase feldspar, amphibole, and pyroxene, giving it a balance between light and dark minerals. Andesite forms from the cooling of magma with a composition between basalt and granite.
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.
Where does andesite form?
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
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 minerals form the rocks diorite and andesite?
The minerals that form diorite include plagioclase feldspar, biotite, and hornblende. Andesite is primarily composed of plagioclase feldspar, pyroxene, and hornblende. Both rocks are intermediate in composition between granite and basalt.
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 rocks and minerals are found in volcanoes?
Volcanoes contain a variety of rocks and minerals such as basalt, andesite, rhyolite, obsidian, pumice, and granite. Volcanic rocks are typically rich in silicate minerals like quartz, feldspar, and olivine, with varying amounts of volcanic glass and pyroclastic material.
