reticulate. adj. 1. (Biology) in the form of a network or having a network of parts: a reticulate leaf. 2. resembling, covered with, or having the form of a net. vb. 3. to form or be formed into a net. [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.
Olivine always has silicon and oxygen as well as iron or magnesium or both, (Mg, Fe)2SiO4. The physical properties of minerals include: How physical properties are used to identify minerals is described in the lesson on Mineral Formation. Mineralogists divide minerals into groups based on chemical composition. mineral is formed through natural processes and has a definite chemical composition. Minerals can be identified by their characteristic physical properties such as crystalline structure, hardness, density, flammability, and color. Minerals are crystalline solids.
