Cards in this set: Term Tetragonal Definition Crystals often long and slender or needle-like. Characteristic forms are 4-sided prisms, pyramids, and dipyramids. common tetragonal minerals are chalcopyrite, zircon, vesuvianite, scapolite, and rutile. Term Isometric Definition generally blocky or ball-like, with many similar and symmetrical faces. forms are cubes, octahedra and dodecahedra. common minerals are galena, fluorite, gold, diamond, and the garnet family. Term Hexagonal Definition generally prismatic or columnar with a rounded triangular or hexagonal cross-section. forms are 3 or 6-sided prisms, pyramids, and rhombohedra. common minerals are quartz, calcite, tourmaline, apatite, and beryl. Term Orthorhombic Definition generally short and stubby with diamond-shape or rectangular cross sections, forms are 4-sided prisms, pyramids, and pinacoids. common minerals are sulfur, topaz, stibnite, and olivine. Term Monoclinic Definition stubby with tilted matching faces at opposite ends forming a somewhat distorted rectangular solid. forms are prisms and pinacoids. common minerals are epidote, monazite, crocoite, brochantite. Term Triclinic Definition usually flattened with sharp edges and thing cross sections. no right angles on faces or edges. forms are pinacoids or pdeions. common minerals are microcline, kyanite, rhodonite, and pectolite. Term Silicate Minerals Definition most abundant mineral group, also most varied and complex because of their structure, three most common minerals are feldspars, micas, and hornblende. Term Carbonates Definition three most common minerals are calcite, aragonite, and dolomite. these minerals are the components of limestone. Term phosphates Definition the most important mineral is a calcium fluorite phosphate called apatite - Ca5F(PO4)3, is used for fertilizer, teeth, and bones. Term Sulfates Definition two most common are closely related calcium sulfates, they are anhydride and gypsum, both from evaporated seawater. Term simple oxides Definition directly bonded to oxygen, no silicon added. most important are iron oxides like magnetite and hematite.
