[C17: from Late Latin rÄticulÄtus made like a net]. (adj. rÉªËtÉªk yÉ lÉªt, -ËleÉªt; v. -ËleÉªt). adj., v. -latâ¢ed, -latâ¢ing. adj. v.t.
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 minerals that make up igneous rocks crystallize at a range of different temperatures. This explains why a cooling magma can have some crystals within it and yet remain predominantly liquid. The sequence in which minerals crystallize from a magma is known as the Bowen reaction series (Figure 3.10 and Who was Bowen). Of the common silicate minerals, olivine normally crystallizes first, at between 1200Â° and 1300Â°C.
