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.
These are all silicate minerals, that is to say they contain silicon and oxygen in their structure. Quartz is pure silicate often called silica, its formula is SiO2. In granite there is free quartz, quartz which is not taken up in the making of the other silicate minerals.he two most common elements are Oxygen (O) at 47% and Silicon (Si) at 28%. Other common elements are Aluminium (Al) at 8%, Iron (Fe) at 5%, Calcium (Ca) at 3.5%, Sodium (Na) at 3%, Potassium (K) at 2.5% and Magnesium (Mg) at just 2%. All the other elements together make up only 1% of the earths crust by weight.
