Minerals

Minerals and Mineraloids. In their overwhelming majority, minerals are crystalline solids forming single crystals.In their crystal structures, atoms, ions and/or molecule groups are periodically arranged to form three-dimensional space lattices.This holds true in spite of numerous lattice defects and irregularities that commonly occur in natural crystals (Chap. 1).
