Pick up the polymineralic rock from the following:
Answer: Option
Explanation:
Granite is a polymineralic rock, which means it is composed of a mixture of minerals. Granite is typically made up of quartz, feldspar, and mica, as well as smaller amounts of other minerals. The different minerals in granite give it a variety of colors and patterns, ranging from white to pink to black.

Polymineralic rocks are rocks formed by more than one type of rock-forming minerals. The rheology of polymineralic rocks is complex as the various minerals within the rock have different deformational behaviors (e.g. Deformation mechanisms, activation energies).

An example of a monomineralic rock is quartzite, which is composed of only quartz.
An example of a polymineralic rock is granite, which is typically composed of quartz, feldspar, and mica. The three basic rock types are igneous, metamorphic, and sedimentary.

Poly means more than 2 (bi) mineralic means composed mineral. Hence polymineralic rock means a rock composed of more than 2 minerals.
Composition of typical granite is Quartz, feldspar* and mica.
* is the most abundant mineral on the earth crust.

Magnesite is a mineral not a rock and pure gypsum is also a mineral (composed of sulphate i.e. CaS04.2H20).
Quartzite is monomineralic consisting quartz, whereas granites have quartz, feldspar & mica.

Granite = mica, felspar, quartz, amphibole.
Pure gypsum = only mineral of sulphates.
Magnesite = mineral which has nickel, iron, cobalt, manganese as an admixture.

Granite is a polymineralic rock because the main composition of granite is Sillica, mica, quarts.
So granite is polymineralic rock.
So granite is polymineralic rock.
