what is feldspar made of? The feldspars are a family of silicate minerals which occur in igneous rocks. There are many different members to the feldspar group. Obviously, silica and oxygen form the foundation for the group, but calcium, sodium, and potassium are also present. One of these elements is usually dominant, but most of the feldspars contain all 3 in varying amounts. It is the proportions of these 3 elements which help determine which specific feldspar is formed.
Peridotite is made only of olivine and pyroxene
Most igneous rocks are made up of silicate minerals, such as quartz, feldspar, mica, amphibole, and pyroxene. These minerals are rich in silicon and oxygen and form the bulk of the composition of igneous rocks.
If you crushed gabbro, you would obtain clasts primarily composed of minerals such as pyroxene, plagioclase feldspar, and olivine. These minerals are common in gabbro, which is a coarse-grained igneous rock primarily made up of these mineral components.
diabase is made out of super codenced lava that was deep in the earths crust
Gabbro is typically lighter than granite because it has a higher density due to its composition of minerals such as pyroxene and plagioclase feldspar. Granite is composed of minerals like quartz, feldspar, and mica, which generally have lower densities.

Mars' crust is primarily made up of basalt rock, similar to Earth's oceanic crust. It also contains minerals like feldspar and pyroxene.
Igneous rocks are usually classified first by their color index. The color index is separated into four categories. Felsic rocks are the lightest and are composed of mostly quartz and potassium feldspar. Intermediate rocks are the second lightest and are made up of mostly plagioclase feldspar, pyroxene, amphibole, and biotite. Mafic rocks are made up of plagioclase feldspar, pyroxene, and amphibole. Ultramafic is made up of mostly olivine, with pyroxene and amphibole.

The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent.

no, Pyroxene is a Mineral not a rock. Rocks are made up of 2 or more minerals
basalt and dacite, and ranges from 57 to 63% silicon dioxide (SiO2)
Andesitic magma is composed of a mixture of silica-rich minerals such as plagioclase feldspar and amphibole. It also contains smaller quantities of pyroxene, biotite, and quartz. Its intermediate composition gives it characteristics of both basaltic and rhyolitic magmas.
