PPT-Unit 2a: minerals & rocks: MINERALS

Geo 281 geology for engineers Geology and Geophysics Department King Saud University Minerals Building Blocks of Rocks We begin our discussion of Earth materials with an overview of mineralogy mineral mineral and LogyStudy because . Chemical Sedimentary Rocks. . Limestone. Chert – Silica. Evaporites. Organic Rocks. Coal. Oil and natural gas. Clastic Sedimentary Rocks. Formed from clasts (bits and pieces of pre-existing rocks) transported, deposited,and lithified. 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. 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. What do rocks look like?. Is this what you thought of?. Or this?. OR THIS????. OR…. THIS!!!!. Rocks can be small or big!. We are going to learn 3 different rocks and how they are made!. Igneous Rock. Color . Texture. Light. Dark. Fine. Coarse . Igneous rocks are classified according to their. . origin. , . texture. , and . mineral composition. .. Origin . D. id it harden inside the earth or on the earth’s surface?. 2 – Soil. 3 – Landscape. Lithosphere. Lithosphere. The lithosphere is a rigid . part of the earth . that includes the earth's crust and part of the upper mantle . Ex. . Mountains, plains, volcanoes, etc.. Sedimentary rocks form in 1 of 3 ways:. 1. . Clastic. Sedimentary Rocks- made of pieces and grains of other rocks. Material such as . sand . or . mud. -usually deposited in . water. Conglomerate sandstone. Standards:. S6E5b. Investigate the contribution of minerals to . rock composition.. S6E5c. Classify rocks by their process of formation.. S6E5d. Describe processes that change rocks and the . excludes synthetic minerals. inorganic. non living processes form them. chemically specific. has a unique proportion of elements. crystalline solid. atoms are arranged in specific 3-D patterns. Definition:. Science Question. . . On Mars, billion-year-old sedimentary rocks containing clay minerals are key indicators of ancient habitable environments and may preserve organic compounds. On Earth, where plate tectonics drives the burial and heating of rocks, clay minerals are transformed into new minerals, influencing organic preservation, and impacting global geochemical cycling of carbon, oxygen, and water. Mars lacked plate tectonics for much of its history, but data from Mars Science Laboratory Rover, . . GLY 4310 - Spring, 2020. 2. Igneous Textures. Phaneritic:. Crystals are readily visible with the unaided eye.. Aphanitic:. Crystals, if present, are too small to be seen with the unaided eye.. Fragmental: . Which of following . is not. one of the three classes of rocks? . . Igneous. Metamorphic. Magma. What two processes change rock into sediments?. Cooling & Hardening. Heat & Pressure. Weathering & Erosion. SEDIMENTARY ROCKS. Geo 281: geology for engineers. Geology and Geophysics Department. King Saud University. What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand .
