  1. What are Minerals Chapter 1 section1

  2. Mineral Structure Mineral Element Compound Crystals Native Element • Is a naturally formed inorganic solid that has a definite crystalline structure • Pure substance that cannot be separated or broken down into a simpler substances by chemical means • 2 or more elements Chemically joined • A solid whose atoms, ions or molecules are arranged in a definite pattern • Composed of only 1 element

  3. Two Groups Of Minerals Silicate Minerals Nonsilicate minerals • A mineral that contains a combination of silicon, oxygen, and one or more metals. • A mineral that does not contain compounds of silicon and oxygen

  4. Common Silicate Minerals Quartz Feldspar Mica • The basic building block of many rocks • Minerals are the main component of most rocks on the Earths surface. • Separates easily into sheets when they break.

  5. Classifications of Minerals Native Elements Carbonates Halides Oxides • Minerals that are composed of only 1 element. • Minerals that contain combinations of carbon and oxygen in their chemical structure. • Compounds that form when fluorine, chlorine, iodine, or bromine combine with sodium, potassium, or calcium, • Compounds that form when an element such as aluminum or iron combine chemically with oxygen

  6. Classifications Cont. Sulfates Sulfides • Minerals that contain sulfur and oxygen. • Minerals that contain 1 or more elements such as lead, iron nickel combined with sulfur
