PPT-Minerals and Rocks 8 th Grade Integrated

SCience Mineral Qualities What is a mineral To be a mineral a substance must have ALL of the following qualities occur naturally formed by nature not by man form from an inorganic process . A homogenous, naturally occurring substance with definable internal structure is called mineral. .. Mode of occurrence of minerals:. (1) In igneous and metamorphic rocks: The smaller occurrences are called veins and the larger occurrences are called lodes. They are usually formed when minerals in liquid/molten and gaseous forms are forced upwards through cavities towards the earth’s surface. Examples: tin, copper, zinc, lead, etc.. Metamorphic Rocks . Are Composed of Sedimentary, Igneous, or Metamorphic Minerals that Have Recrystallized.. Marble from Carrara, Italy. Pre-existing sedimentary, igneous, or metamorphic rock changed to a new assemblage of minerals. . UNIT . - . 6. What is Metamorphism. Metamorphism. (from the Greek words for “changing form”) is the process by which rising temperature and changes in other environmental conditions transform rocks and minerals. Granite, Alkali Feldspar Granite, Granodiorite, Quartz Monzonite, and Monzonite. 2. IUGS Intrusive Igneous Rock Chart . 3. “Granite”. Rocks in this lab are plutonic. They formed by very slow cooling and show corresponding large crystals. LOWER-GRADE REGIONAL METAMORPHICS. Slate, Phyllite, . “Greenstone” and Schist. 2. Metamorphic Rock Definition. A sedimentary, igneous, or previously existing metamorphic rock which has undergone textural, structural, and/or mineralogical changes due to the action of one or more agents of metamorphism. GLY 2010 - Summer 2016 - Lecture 11. 2. Metamorphism. The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions. 3. Metamorphic Rock. Any rock derived from pre-existing rocks by mineralogical, chemical, and/or structural changes, essentially in the solid state . LOWER-GRADE REGIONAL METAMORPHICS. Slate, Phyllite, . “Greenstone” and Schist. 2. Metamorphic Rock Definition. A sedimentary, igneous, or previously existing metamorphic rock which has undergone textural, structural, and/or mineralogical changes due to the action of one or more agents of metamorphism. Color .
