What are the dominate compounds of clay, silt, and sand in soil?

For example, what are the dominate 5 compounds in clay mineral? 80% of SiO2, etc.?

Is the proportion/order of these dominate compounds changed with other factors, e.g., pH?

Thank you in advance.

Gordon Foli

Basically secondary minerals: Consider the Ferro-magnesian and Alumino oxides or oxy-hydroxides.
