Sedimentary rocks cover ~ 75% of Earth’s surface. ~ 5 % (by volume) of Earth’s outer 10 miles. Contain evidence of past environments:. Important resource. Coal, oil, and other fossil fuels. Groundwater resources. 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. HIGHER-GRADE REGIONAL METAMORPHICS. Gneiss and Eclogite. 2. High-Grade Regional Metamorphic Facies. Rocks in this laboratory represent high to very high grade regional metamorphic rock. Facies represented are the amphibiolite, granulite, and eclogite facies. Rocks that crystallized directly from a melt. Igneous rocks . Form as magma cools and crystallizes . Rocks formed inside Earth are called . plutonic. or intrusive rocks . Rocks formed on the surface . HIGHER-GRADE REGIONAL METAMORPHICS. Gneiss and Eclogite. 2. High-Grade Regional Metamorphic Facies. Rocks in this laboratory represent high to very high grade regional metamorphic rock. Facies represented are the amphibiolite, granulite, and eclogite facies. 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. Solar System Review. The rocky planets are closest to the Sun.. The rocky planets are smaller than the gas giants.. Solar System Review. The rocky planets have fewer moons (0 to 2).. The rocky planets’ days are long (24 hours to . UNIT . 5. What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . which are . transported by the action of water, wind, glacial ice and . gravity.. These . materials are . CSC 600: Data Mining. Class 16. Today…. Measures of . Similarity. Distance Measures. Nearest Neighbors. Similarity and Dissimilarity Measures. Used by a number of data mining techniques:. Nearest neighbors. Types of Rocks. Rock: an aggregate of one or more minerals. Igneous Rocks: crystallize from a magma. Sedimentary Rocks. Clastic: formed by the erosion of pre-existing rocks. Chemical/Biochemical: precipitated from chemical reactions. Sedimentary Rocks. Metamorphic Rocks. 1. NPS. Why are minerals & rocks important?.
