This is the most important difference between most igneous monomineralic rocks which need to be more than 90.
Is marble monomineralic.
Common monomineralic metamorphic rocks are marble and quartzite although they do not need necessarily to be monomineralic.
Common monomineralic metamorphic rocks are marble and quartzite although they do not need necessarily to be monomineralic.
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 pure.
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.
Similar is the situation with their sedimentary protoliths limestone and sandstone which may be very.
Examples would include the igneous rock anorthosite composed entirely of plagioclase feldspar and the metamorphic rock marble composed entirely of calcite.
Monomineralic igneous rocks are dunite more than 90 olivine and anorthosite more than 90 plagioclase feldspar.
