Is feldspar extrusive or intrusive?
It is actually a mineral that appears in both extrusive and intrusive igneous rocks.
Is feldspar a rock or mineral?
Feldspar is the name of a group of rock-forming minerals which make up as much as 60% of the Earth's crust. Feldspars crystallize from magma in both intrusive and extrusive rocks, and they can also occur as compact minerals, as veins, and are also present in many types of
What igneous rock is made up of mica feldspar and quartz?
The list is long, but let's go with granite.
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 feldspar a compound or mixture?
Feldspar is a mixture.
