PPT-Mineral Properties Key Concepts

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. IOCG. deposits in the NT. Anthony . Schofield and . David . Huston. Targeting uranium and copper-gold systems in Australia using a mineral systems approach. Challenges:. ~80% covered. Relatively small footprint of most mineral deposits. 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.. GLY 4200 - Lecture 2 –Fall, 2016. 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. Bellwork. 9-13-16. Get out the video notes to check.. Objectives. Students will be able to identify how the earth is affected by long- term and short- term geological cycles and the influence of man.. A . mineral. is a substance with these characteristics:. Solid. Naturally. Occurring. Inorganic. (never lived, although graphite, diamond, and calcite may be byproducts of organisms). Definite . Chemical Composition. 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. 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. 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. PURPOSE. Describe what . PRECISION . means for the purpose of these modules. Make an . IMPRECISE ITEM. . MORE. . PRECISE.
