PPT-Properties of Minerals

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. 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.. 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). 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.. …the same type of mineral! They are examples of quartz!!. Haha! Tricked you! These are all…. There are over 3000 types of minerals in the Earth’s crust. As you could see with the quartz, often times even the . 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.. What makes minerals and rocks ?. Fe, Mg, Si, O, K. chemical compounds. igneous, sedimentary, metamorphic . silicon (Si). oxygen (O). iron (Fe). quartz. orthoclase. biotite. granite. sandstone. gneiss. A. Definition – four part definition. . . Naturally occurring. . . Inorganic substance (non-living). . . Crystalline solid. . . Definite chemical composition.  .  .  .
