Homework Equations

The Attempt at a Solution

I am having trouble finding research on the general properties of quartz, feldspaar, and clay mineral substances.
Is it correct that quartz heavy materials tend to be more dense and hard. And feldspaar tends to be more porous but less dense? What general trends exist for quartz, feldspaar, and clay heavy materials?

Thanks a lot!

They are all silicates. Wikipedia has the data you want.
Quartz is a 3D, tightly bonded SiO2 crystal.

There are several sorts of feldspar.

There are several sorts of clay, they are sheet structures and absorb water and ions. If you heat them they become mica.
