Mar 14, 2020· Basalt is composed of plagioclase and pyroxine minerals. If you're studying rocks, these terms will come up often. Pyroxine is a class of rock-forming silicate minerals, generally containing the chemical elements calcium, magnesium, iron, and occasionally the mineral olivine. In lesser quantities, basalt may also contain the mineral quartz, hornblende, nepheline, orthopyroxene, etc.

Jan 23, 2020· Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks. And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its density.
Granite is a crystalline igneous rock that consists largely of feldspar and quartz.These two are the most common minerals in the crust which means that granite too is among the most ubiquitous rock types, especially in the upper continental crust..

At these depths, magma is insulated by the rocks around it and cools very slowly, growing large interlocking crystals. Granite is often said to have a "salt-and-pepper" appearance: the lighter-colored minerals are quartz, potassium feldspar, and plagioclase feldspar, and the darker-colored minerals are mostly biotite and hornblende.
The term "granite" is used for granite and a group of intrusive igneous rocks with similar textures and slight variations in composition and origin. These rocks consist mainly of feldspar, quartz, mica, and amphibole minerals, forming an interlocking, somewhat equigranular feldspar and quartz matrix with dispersed darker biotite mica and ...
