Role of the Geological Survey. Mineral Systems and Mineral Potential Mapping Research in GSSA. Geologists use characteristics to tell one mineral from another. What is a Mineral?. Must be a solid.. Must occur in nature.. Must have a definable chemical composition (. NaCl. ).. Must have a crystalline structure.. UNIT -4. They assist in the identification of minerals – . study their optical properties under the microscope. . . Minerals . are inorganic chemical compounds having a certain lattice shape, size and symmetry, being a result of the geometrical arrangement of the constituents (chemical elements such as Si, Al, O, . 2. Hardness . Hardness may be measured in several ways. Moh’s scale – developed by Austrian mineralogist Friedrich Mohs in 1824. Absolute scales – Brinell, Knoop, Rockwell, Vicker’s. 3. Moh’s Scale. naturally occurring, . inorganic solid . with a specific chemical composition . a definite crystalline structure. Minerals can form from the cooling of magma which is the molten material found beneath Earth’s surface as magma rises closer to the surface the molten compounds no longer move freely and they begin to interact chemically to form minerals. All rocks are made up of 2 or more of these minerals. . Minerals are not rocks!. Silicon and oxygen are the most abundant elements in the crust and in minerals. Oxygen is the most abundant element in minerals. A pure substance, such as a mineral, can be identified from observations and tests performed to determine its physical properties. These properties are based on the unique structure of the substance.. Bell Work 9/2/14 1 What element is Group 1 and Period 4? Potassium 2. What is that element ’ s atomic number? 19 3.
