An example of a polymineralic rock is granite which is typically composed of quartz feldspar and mica.
The feldspar part of granite breaks down over the ages to form the primary component of clay.
Gabbro any of several medium or coarse grained rocks that consist primarily of plagioclase feldspar and pyroxene essentially gabbro is the intrusive plutonic equivalent of basalt but whereas basalt is often remarkably homogeneous in mineralogy and composition gabbros are exceedingly variable gabbros are found widely on the earth and on the moon as well.

Monomineralic rocks as the name suggests are rocks that are composed of only one mineral.
Two types of rocks with similar uniaxial compressive strength are chosen.
Weathering breaks apart granite s two major components.
Majority of rocks are composed of several different minerals and absolutely pure monomineralic rocks do not exist in nature anyway.
But some of them are reasonably pure to be called monomineralic.
Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.
The three basic rock types are igneous metamorphic and sedimentary.
These are the manganese nodules and metalliferous sediments.
