PPT-MINERALS Characteristics and Properties

Mineral Characteristics What is a mineral Naturally occuring Not manmade synthetic or biologically produced Pearls styrofoam charcoal are not minerals Inorganic Not formed from processes involving organisms living or once living. 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, . 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.. Standard: S6E5b. Investigate the contribution of minerals to rock composition.. There are five characteristics of a mineral. F. ive characteristics. . of a mineral:. Solid—A mineral is always a solid, with a definite volume and shape.. 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.

Definition:. As clay is the chief ingredient in most ceramic bodies, it is important to know as much about its properties as possible in order to understand its function and possibilities.. The most important properties of clays are:. EPSS 51. Adapted from Greg . Druschel. , University of Delaware. Optical Microscopy.
