carbonate model, shows how the chemicals react to make a carbonate mineral. sulfate model, how a sulfate mineral forms, and the ions. Halide mineral that is common in the Halide mineral group, was formed by the Halide chemical composition.

- Notes - page 95 - 97 - The two most common carbonate minerals are calcite and dolomite. - They are physically and chemically alike -They are even found on the same continents -When calcite is dominant mineral it is called limestone dolomite is dominant it is dolostone - Halite is common as table salt Page 647-650 - Weathering and ore deposits secondary enrichment - takes place in one or two ways. - Bauxite - are made from the process of weathering and the third most abundant mineral. - forms in rainy tropical climates - it is used to make aluminum - elements in it are calcium sodium and silicon -other deposits are pyrite which forms under chemical weathering and then makes sulfuric acid. -Ore is economically used. -Placer deposits ::: like- sized grains that are deposited together, gold,silver - Placers involve minerals but they are durable to weathering and chemically resistance -you can not see theses, it is a process that makes up other minerals. -they are used in building materials - concrete etc.. - We use minerals for a lot of commercial use and for building materials - fertilizers sulfur and salt
