Scientists use characteristics to tell one mineral from another Mineral Properties we will be investigating Luster Hardness Streak Transparency Luster Refers to the way light reflects from the surface of the mineral . So what is a mineral?. What are the characteristics of all minerals?. Mineral . Characteristics. 1. A mineral occurs naturally.. 2. A mineral is solid.. 3. A mineral has a definite chemical composition.. 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.. These notes go on pages 5 and 7 of your INB!. http://www.mii.org/www.mii.org. General Facts about Minerals. Between 2 - 3,000 have been identified. A few are . “native elements” . -- made of only one element, such as sulfur, gold. copper, and graphite (carbon). 1) Rocks cannot be made of organic material. 2) Luster is classified as metallic and non-metallic. 3) Scientist use tests to identify minerals. 4) Minerals that make up rocks can be mined as ores. 5) A liquid or gas can be classified as a mineral. Chapter 5. Minerals of Earth’s Crust. Chapter. 5. Standards. SES3d. Explain . the processes that transport and deposit material in terrestrial and marine sedimentary basins, which result, over time, in sedimentary rock. . 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. Mineral Characteristics. What is a mineral?. Naturally . occuring. Not . man-made. (synthetic) or biologically produced. . Pearls, . styrofoam. , charcoal are not minerals. Inorganic. Not formed from processes involving organisms (living or once living). Standard: S6E5b.
