Notes

(Richard Willis)

The crystallized aggregates of atomic elements, morphologically distinguishable by 32 possible geometrical shapes (symmetry elements and their combinations) which in turn can be grouped into six crystal systems according to the complexity of their symmetries: isometric, hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic. The aggregates (elements combined forming a given mineral) are determined by chemical bonding, which can occur electrostatically, electron-sharing, metallicazation, or residuali zation. Bonding effects hardness, density, solubility, melting point, tenacity, specific gravity, magnetism, structural properties, colors, etc. Subsequently, minerals can be classified into 11 groups according to chemical and physical properties: native elements, sulfides, sulfosalts, oxides and hydroxides, halides, carbonates, nitrates, borates, sulfates, phosphates, and silicates. see individual listings for further details
