Monomineralic applied to rocks composed of one mineral type only.
Is marble monomineralic.
Marble is commonly used for sculpture and as a building material.
One is granite which is an igneous rock that is polymineralic the other is marble which is monomineralic and relatively homogeneous.
The mineral content and grain structure of two rock types are identified using petrographic thin sections.
Two types of rocks with similar uniaxial compressive strength are chosen.
Similar is the situation with their sedimentary protoliths limestone and sandstone which may be very.
Common monomineralic metamorphic rocks are marble and quartzite although they do not need necessarily to be monomineralic.
Examples would include the igneous rock anorthosite composed entirely of plagioclase feldspar and the metamorphic rock marble composed entirely of calcite.
Similar is the situation with their sedimentary protoliths limestone and sandstone which may be very pure.
This is the most important difference between most igneous monomineralic rocks which need to be more than 90.
