Why do scientists theorize that kimberlites originate deep within the earth crust or mantle?
because diamond and other minerals found in kimberlites can form only under very high pressures
What is rose quartz made out of?
Rose quartz is formed when a small amount of iron is incorporated into a pure quartz (SiO2) matrix. The inclusion of iron (Fe2O3) in many minerals s responsible for the colors that are observed. Iron also turns quartz into Amethyst.
Is every part of quartz the same?

Can gabbro contain the moneral quartz?
Although gabbro is low in silica and has no quartz there are quartz gabbro's. Quartz gabbro's are thought to occur from magma that was over-saturated with silica.
Diamond falls under which category of rocks?
Igneous rocks are the category of rocks that contain diamonds. The two types of igneous rocks that form diamonds are kimberlites and lamproites.

Quartz.
Is quartz igneous?
Theoretically yes, though any given sample of quartz may contain inclusions (non-quartz stuff trapped inside) making it heterogeneous.
Does andesite contain little or no quartz?
