The term âolivineâ is also used for a group of related minerals that all share similar crystal structures and the same general chemical composition of X 2 SiO 4, where X can stand for iron (Fe), magnesium (Mg), calcium (Ca), manganese (Mn) or nickel (Ni).uartz can only form from magmas that are relative rich in silica, while the olivine minerals only form from magmas that are relatively lean in silica, so quartz and olivine are incompatible minerals.
The Mineral orthoclase. Orthoclase is one of the most common minerals, and occurs in numerous mineral environment s. It is polymorphous with the minerals Microcline and Sanidine. These three minerals form the Potassium Feldspar group.They are almost identical in physical properties, and it is sometimes impossible to distinguish one another without x-ray analysis. The only difference between them is their crystal structure.t is polymorphous with the minerals Microcline and Sanidine. These three minerals form the Potassium Feldspar group.
