Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite and hypersthene with olivine. Mafic is an adjective describing a Silicate mineral or rock that is rich in magnesium and iron the term was derived by contracting "magnesium" and "ferric" In Geology, an intrusion is a body of Igneous rock that has Crystallized from molten Magma below the surface of the Earth. Igneous rocks (etymology from Latin ignis, fire are rocks formed by solidification of cooled Magma (molten rock Calcium (ˈkælsiəm is the Chemical element with the symbol Ca and Atomic number 20 Plagioclase is a very important series of tectosilicate Minerals within the Feldspar family Labradorite ((CaNa(AlSi4O8 a Feldspar Mineral, is an intermediate to calcic member of the Plagioclase series Hypersthene is a common rock-forming inosilicate Mineral belonging to the group of Orthorhombic Pyroxenes Many references have formally abandoned The Mineral olivine (when gem-quality also called Peridot) is a Magnesium Iron silicate with the formula ( Mg Norite is essentially indistinguishable from gabbro without thin section study under the petrographic microscope. Gabbro (ˈɡæbrəʊ is a dark coarse-grained intrusive Igneous rock chemically equivalent to Basalt. In Optical mineralogy and Petrography, a thin section is a Laboratory preparation of a rock, Mineral or Soil sample for A petrographic microscope is a Microscope used in Petrology and Optical mineralogy to identify rocks and Minerals in Thin sections It occurs with gabbro and other mafic to ultramafic rocks in layered intrusions which are often associated with platinum orebodies such as in South Africa, the Skaergaard igneous complex of Greenland, and the Stillwater igneous complex in Montana, USA. Ultramafic (also referred to as ultrabasic) rocks are igneous and meta -igneous rocks with very low Silica content (less than 45% generally Ultramafic to mafic layered intrusions are found in typically ancient Cratons and are rare but worldwide in distribution Platinum (ˈplætɪnəm is a Chemical element with the Atomic symbol Pt and an Atomic number of 78 An ore is a volume of rock containing components or Minerals in a mode of occurrence that renders it valuable for mining The Republic of South Africa (also known by other official names) is a country located at the southern tip of the continent of Africa The Skaergaard Intrusion is a layered Gabbro complex in East Greenland, located at. Greenland (Kalaallit Nunaat meaning "Land of the Greenlanders" Grønland is a self-governing Danish Province located between the The Stillwater igneous complex is a large ultramafic to mafic layered intrusion located in southern Montana in Stillwater, Sweet Grass and Montana ( is a state in the Western United States. One-third of the state in the western part contains numerous mountain ranges (approximately 77 named of the northern The United States of America —commonly referred to as the Norite is also the basal igneous rock of the Sudbury Basin complex in Ontario which is the site of a meteorite impact and the world's second largest nickel mining region. The Sudbury Basin, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is the second largest known Impact crater or Astrobleme Ontario (ɒnˈtɛrioʊ is a province located in the central part of Canada, the largest by population and second largest after Quebec See also Impact crater An impact event is the Collision of a large Meteoroid, Asteroid or Comet (generically Nickel (ˈnɪkəl is a metallic Chemical element with the symbol Ni and Atomic number 28 Norite is a common rock type of the Apollo samples. Moon Rock is the debut Album by Paul Steel. It was cancelled for release after the album's first single Your Loss failed to chart upon On a smaller scale, norite can be found in small localized intrusions such as the Gombak Norite in Bukit Gombak, Singapore. In Geology, an intrusion is a body of Igneous rock that has Crystallized from molten Magma below the surface of the Earth. Bukit Gombak is a neighbourhood in the west-central area of the Southeast Asian City-state of Singapore. Singapore
