mineral species- collection of specimens that exhibit similar internal structures and chemical compositions
mineral classes are divided into groups based on similarities in atomic structures or compositions
silicates-most dominant mineral class
nonsilicates- other mineral classes that are less abundant than the silicates
-every silicate mineral contains oxygen+silicon
fundamental building block= silicon-oxygen tetrahedron...consists of 4 oxygen anions
feldspar group-most common group, has 2 planes meeting at 90 degree angles and have a luster that ranges from glassy to pearly
muscovite-light in color and has a pearly luster
clay minerals-variety of complex minerals that have a sheet structure
dark silicates- those containing ions of iron
olivine group- family of high temperature silicate minerals that are black to olive green
pyroxene group- group of complex minerals that are imp. to earths mantle
garnet-similar to olivine other than that its structure is linked by metallic ions
