Pick up the polymineralic rock from the following:
Quartz sand
Pure gypsum
Magnesite
Granite
None of these.
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).

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.
