What do all these minerals quartz plagioclase feldspar microcline feldspar hornblende and biotite have in common?
All of these minerals are silicate minerals, meaning they are composed of silicon and oxygen atoms. Quartz, plagioclase feldspar, microcline feldspar, hornblende, and biotite all belong to the larger group of silicate minerals, which make up the majority of the Earth's crust. These minerals also exhibit varying degrees of hardness, cleavage, and color, but their commonality lies in their fundamental chemical composition as silicates.

Which mineral is commonly found in the three matamorphic rocks slate schist and gneiss?
granite
What kind of minerals does not go with quartz feldspar fluorite or hornblende?
Fluorite does not go with the others. It belongs to Halide minerals, while the others (quartz, feldspar, and hornblende) belong to Silicate family of minerals.
What is the most common group of silicates?
The most common group of silicates is the feldspar group, which includes minerals like orthoclase, plagioclase, and microcline. Feldspar minerals account for about 60% of the Earth's crust and are essential components of many igneous, metamorphic, and sedimentary rocks. They are characterized by their framework structure and are primarily composed of aluminum, silicon, and oxygen, often with varying amounts of other elements.
What minerals can you identify in the specimen of gabbro?
The minerals that make up Gneiss are almost always: feldspars, quartz, and mica. Sometimes: kyanite, garnet, hornblende, tourmaline, magnetite, and many others. Source: Geology University Student
Is granite the same mineral as quartz?
The most abundant minerals in granite are potassium feldspar, plagioclase feldspar, and quartz; with differing amounts of muscovite, biotite, and hornblende-type amphiboles. The most abundant minerals in basalt are amphibole and pyroxene, sometimes plagioclase, feldspathoids, and/or olivine. In other words, no.
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.
Which mineral is commonly found in the three matamorphic rocks slate schist and gneiss?
granite
What is the mineral composition of syenite?
Syenite is primarily composed of alkali feldspar minerals such as orthoclase and plagioclase feldspar, along with small amounts of other minerals such as quartz, hornblende, and mica. It lacks significant amounts of calcium-rich plagioclase feldspar, which distinguishes it from granite.
What four minerals make up rocks in the intermediate family?
The four minerals that make up rocks in the intermediate family are plagioclase feldspar, amphibole (such as hornblende), biotite, and quartz. These minerals are typically found in rocks like diorite and andesite, which have a composition between felsic and mafic rocks.
What minerals are in bojite?
Plagioclase and Hornblende
What are the ten most rock- forming minerals?
Quartz, Potassium Feldspar, Plagioclase Feldspar, Muscovite (mica), Biotite (mica), Amphibole (hornblende), Pyroxene, Olivine, Calcite, Dolomite.
What minerals are in amphibolite?
The minerals in amphibolite are hornblende and plagioclase. Plagioclase are minerals that belong to the feldspar family. Other minerals in amphibolite are garnet, magnetite, quartz, and pyroxene.
What are the two main feldspar groups?
The two main feldspar groups are potassium feldspar (orthoclase and microcline) and plagioclase feldspar (albite and anorthite). They are common rock-forming minerals in the Earth's crust and are essential components in many igneous and metamorphic rocks.

What are the main minerals in Texas?
Carbon in its many forms including oil and natural gas.
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.
What kind of minerals does not go with quartz feldspar fluorite or hornblende?
Fluorite does not go with the others. It belongs to Halide minerals, while the others (quartz, feldspar, and hornblende) belong to Silicate family of minerals.
