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 most commonly encountered minerals in the garnet group include almandine, pyrope, spessartine, andradite, grossular, and uvarovite. They all have a vitreous luster, a transparent-to-translucent diaphaneity, a brittle tenacity, and a lack of cleavage.arnet is the name used for a large group of rock-forming minerals. These minerals share a common crystal structure and a generalized chemical composition of A 3 B 2 (SiO 4) 3. In that composition A can be Ca, Mg, Fe 2+ or Mn 2+ , and B can be Al, Fe 3+ , Mn 3+ , V 3+ or Cr 3+ .
