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 else can I help you with?
Which mineral can be found in all samples of rhyolite and andesiteh igneous rock is dark colored cooled rapidly on Earth's surface and is composed mainly of plagioclase feldspar olivine and pyroxene?
The mineral that can be found in all samples of rhyolite and andesite is typically plagioclase feldspar, which is often present in varying compositions. Rhyolite and andesite are both volcanic rocks that cool relatively quickly on the Earth's surface, leading to their fine-grained textures. While olivine and pyroxene can also be present in these rocks, plagioclase feldspar is the primary mineral characteristic of both rhyolite and andesite.
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.
What voltaian rocks?
Volcanic rocks are rocks that form from the solidification of molten lava and can be found near or on volcanoes. They are typically fine-grained due to rapid cooling and can contain minerals such as basalt, andesite, and rhyolite. Volcanic rocks are common in areas with tectonic activity and can provide important clues about the history of volcanic eruptions.
What types of igneos rocks are found in Mount Tambora?
Mount Tambora in Indonesia primarily consists of andesite and dacite rocks. These igneous rocks were formed from the cooling and solidification of magma beneath the Earth's surface. Andesite is a fine-grained rock that is intermediate in composition between basalt and rhyolite, while dacite is a fine-grained volcanic rock with a similar composition to andesite but with higher silica content.
Is a mineral formed by cooling after a volcanic eruption?
yes they are but only because of metamorphosis and the reaction the mineral has. The mineral takes years maybe century's to cool down. it has a crystallized diamond shape and can be found in many shapes, and colors.

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 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 type of crystal are formed from in extrusive igneous rocks?
Extrusive igneous rocks form fine-grained crystals due to rapid cooling at Earth's surface, resulting in minerals like basalt, andesite, and rhyolite. These rocks cool quickly, preventing the formation of large crystals typically found in intrusive igneous rocks.
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 pair of minerals is most likely to be found in felsic rock?
Quartz and feldspar are the most likely pair of minerals found in felsic rock. Felsic rocks are rich in silica, which forms minerals like quartz, and feldspar is another common mineral found in these rocks.
What From what mineral does an extrusive rock form?
Extrusive rocks, also known as volcanic rocks, primarily form from the cooling and solidification of magma that erupts onto the Earth's surface as lava. The minerals found in these rocks typically include basalt, rhyolite, and andesite, which are composed of silicate minerals such as quartz, feldspar, and pyroxene. As the lava cools quickly upon exposure to air or water, it solidifies into fine-grained textures. Thus, extrusive rocks are primarily associated with volcanic activity and the minerals present in the erupted magma.
How is uranium found?
Analyzing samples of soils and waters, examinations of minerals, radiometric measurements in territory (also air surveillance).
