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 many quartz varieties include citrine, amethyst, ametrine, chalcedony, aventurine, onyx, agate, tiger's eye, smoky quartz and rose quartz. But from the viewpoint of mineralogy, it is feldspar that is the most common mineral.In fact feldspar makes up nearly 60% of the Earth's crust. Feldspar is a group of minerals distinguished by the presence of aluminum silicates with potassium, sodium, calcium and barium.he many quartz varieties include citrine, amethyst, ametrine, chalcedony, aventurine, onyx, agate, tiger's eye, smoky quartz and rose quartz.
