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.
Is gabbro intrusive or extrusive?
Gabbro is a type of intrusive igneous rock that forms beneath Earth's surface from the slow cooling of magma. It is composed mainly of pyroxene, plagioclase feldspar, and minor amounts of olivine and amphibole. Its coarse-grained texture is a result of the slow cooling process.
What is the difference between diabase and diorite?
Diabase is a mafic, fine-grained igneous rock composed mostly of plagioclase feldspar and pyroxene. Diorite is also an igneous rock, but it is intermediate in composition between mafic and felsic, consisting mainly of plagioclase feldspar and amphibole. The main difference lies in their mineral compositions, with diabase containing more pyroxene and diorite containing more amphibole.
What are two feldspars found in granite?
Granite contains plagioclase feldspar and potassium feldspar. It really depends on the composition of the magma from which it forms. If the granite has a lot of pink in it, chances are it is potassium feldspar (K-Spar). If it is dominated by white, then the feldspar is probably plag.
What intrusive igneous rock has the same mineral composition as basalt?
Gabbro is an intrusive igneous rock that has the same mineral composition as basalt. Both rocks are composed primarily of plagioclase feldspar and pyroxene minerals.
What is Obsidians' composition?
potassiun feldspar, quartz, plagioclase feldspar,biotite, and amphibole.
What is the mineral of andesite?
plagioclase feldspar, pyroxene, horneblende (amphibole)

What type of rock is hornblende diorite?
Hornblende diorite is a type of intrusive igneous rock. It is composed primarily of plagioclase feldspar, hornblende, and small amounts of other minerals. It has a medium to coarse-grained texture and is typically gray or greenish in color.
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.
How is granite and rhydoite similar?
they both contain the minerals quatz,feldspar,muscovite,amphibole,plagioclase

What minerals make up monzinite?
Monzinite is a rock composed mainly of potassium feldspar, plagioclase feldspar, and quartz. Other common minerals found in monzinite include biotite mica, amphibole, and occasionally garnet and other accessory minerals.
Sand collected at a beach contains a mixture of pyroxene olivine amphibole and plagioclase feldspar . The rock from which this mixture of sand came is best described as?
The rock most likely belongs to the igneous category, such as a basalt that contains pyroxene, olivine, amphibole, and plagioclase feldspar.
