What else can I help you with?
Is andesite plutonic?
No. It is volcanic. The plutonic equivalent of andesite is diorite.
What minerals form the rocks diorite andesite?
the minerals are olivine and pyroxene ..you're welcome
Is andesite intusive?
Andesite is a type of igneous rock that can form both intrusively (inside the Earth's crust) and extrusively (on the Earth's surface). When andesite forms intrusively, it typically cools slowly and can create large crystals.
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.
Do diorite and rhyolite have the same chemical composition?
No, diorite and rhyolite have different chemical compositions. Diorite is a coarse-grained intrusive igneous rock composed mainly of plagioclase feldspar and amphibole, while rhyolite is a fine-grained volcanic rock composed predominantly of quartz, feldspar, and mica.
Is andesite plutonic?
No. It is volcanic. The plutonic equivalent of andesite is diorite.
Is andesite an extrusive rock?
Yes. Andesite is the extrusive equivalent of diorite
Compare the mineral composition of diorite with the mineral composition of andesite?
Both andesite and diorite are igneous rocks with an intermediate color index. Diorite; however, is intrusive and phaneritic, whereas andesite is aphanitic and extrusive. Andesite is said to be the extrusive equivalent of diorite. Diorite is made up of plagioclase feldspar and ferromagnesian mineral crystals, mainly amphibole. Contrarily, andesite may resemble rhyolite, meaning it presents a need for microscopic examination to see its mineral crystals. The two have a composition of plagioclase feldspar and amphibole, but it is much more difficult to detect in andesite.
Distinguish between andesite and diorite using two physical properties of igneous rocks?
Andesite typically has a light to dark gray color with a fine-grained texture, while diorite is usually darker in color with a coarse-grained texture. Additionally, andesite usually contains more silica than diorite, leading to differences in their mineral compositions and overall chemical makeup.
Can andesite be mined in australia?
Andesite is the eruptive version of plutonic diorite. The name comes from the Andes, where it is the common volcanic ejecta.
What minerals form the rocks diorite andesite?
the minerals are olivine and pyroxene ..you're welcome
What is the main difference between andesite and diorite?
Both are igneous rocks of intermediate coposition.
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 are 12 types of igneous rocks?
diorite,gabbro,granite,obsidean,pumice,rhyolite,andesite
Coarse grained diorite is most similar in mineral composition to fine grained?
granodiorite, as both rocks are primarily composed of plagioclase feldspar, quartz, and biotite. However, coarse grained diorite will have larger crystal sizes compared to the fine grained counterpart.
Is andesite intusive?
