Ore minerals occur as disseminations and in stockworks of veins in hydrother mally altered, shallow intrusive complexes, often porphyritic, and in adjacent country rocks. This model covers all porphyrystyle copper deposits and includes coppermolybdenum, coppermolybdenumgold, and coppergold subtypes that are sometimes distinguished by economic geologists (for example, Sillitoe, 2000). A ...

In 1997, Argentina positioned itself among the copper producers thanks to Bajo de la Alumbrera, and other ore deposits are confirmed such as San Jorge, Taca Taca, El Altar, Campana Mahuida, Los Azules, El Pachón, Famatina, José María, and Agua Rica, among others. Despite ten gold and silver mines operating today, no copper mines have been opened since Alumbrera.

relationship between the Mesozoic ore deposits and Mesozoic volcanic–intrusive complexes. Zircon U–Pb dating of the orerelated intrusive rocks and molybdenite Re–Os dating from two typical deposits (Tongcun Mo deposit and Zhilingtou Au–Ag deposit) in the two metallogenic belts show the early and late Yanshanian ages for mineralization.

At the time, BCL was owned jointly by Rio Tinto (%), the PNG Government (%) and public shareholders (%). Community unrest that began in 1988 forced BCL to suspend ...
PORPHYRY Cu (MoAu) deposits form in the upper crust, where fluid overpressures generated in the cupola of a crystallizing magma hydrofracture the overlying rock (Burnham, 1979), allowing magma and fluids to intrude, forming porphyry dikes surrounded by stockwork fractures. Aqueous fluids permeate the fractured rock where the fluids depressur

Molybdenum (Mo) is a refractory metallic element used principally as an alloying agent in steel, cast iron, and superalloys to enhance hardenability, strength, toughness, and wear and corrosion resistance. To achieve desired metallurgical properties, molybdenum, primarily in the form of molybdic oxide or ferromolybdenum, is frequently used in combination with or added to
Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and chemical formula is MoS 2.. The compound is classified as a transition metal is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum. MoS 2 is relatively unreactive. It is unaffected by dilute acids and oxygen.
