Look out for rock forming minerals here

Alkali and earth alkali compounds tend to be rather soluble in binary compounds (you won't find many there) in ternary and higher compounds they tend to form less water soluble minerals. See: compounds with s-block metals

most common metal rich core mantle transition zone minerals

In the earths mantle and crust silicon and oxygen are the most abundant elements. On the borther to earths outer core this changes to iron and nickle. Down there the most abundant minearls are made from mixture of those elements. As a sidenote: In nature when iron rich metal is available in stochiometric excess heterogenous pallasite is formed. This rock looks really beautiful and can be found in some meteroids - recommendation to check it out.

Of interest as diamondoid materials may be the pure end members of the mixing series:

related minerals:

Another interesting tertiary material would be CSiO 4
a solid intermediate material between CO2(gas) SiO2(solid quartz): [1] (A prototypical pseudo phase diagram.)

The spinell group (wikipedia)

These oxide minerals are devoid of the ubiquitously present silicon.

aluminum spinells

iron spinells
