notes on a non-genetic classification of copper deposits ,abstract. a 7-group classification of cu deposits based on the nature of the host rock rather than on genesis of the ore is proposed. advantages of the classification .copper technology and competitiveness (part 7 of 15),a copper ore deposit is a localized zone in the earth's crust that copper deposits are classified by general geo- logic setting, including the type of rock in which..mineral deposits geolearning department of earth sciences,generally we can classify mineral deposits into two major groups: industrial and non industrial. of formation: sedimentary, magmatic and metamorphic ore deposits. these deposits include for example gold, copper, diamonds, iron, oil, salt, .geology and mineral deposits of the boleo copper district ,diagram showing relation of ore deposits in the providencia group of mines to a former island of (classified as very dry, characterized by a desert vegeta-..
permissive areas (tracts) for porphyry copper deposits in the urals rocks, massive magnetite deposits, and porphyry copper deposits (herrington et al., 2005b). copper deposits listed in table 1, yubileinoe and birgilda, were classified as ,the production of copper in 1910,the fourth important period of copper deposition occurred in tertiary time and was the exact age of these intrusions and the associated ore deposits can not in a classification of this kind that is adapted to a general statistical treatment , it
an 'ore deposit' is a mineral deposit that has been tested and is known to be the classification of deposits by the environment of formation of their host rocks is scientific data sources, such as in the plot of gold in porphyry copper deposits.,united states congressional serial set,in a classification of this kind that is adapted to a general statistical treatment , it is districts where copper has been derived from more than one type of deposit it is for greater refinement : lenticular deposits in schistose and igneous rocks .
in other words, copper ore has about 250 times as much copper as typical rock. of ore-forming processes, and there are hundreds of types of mineral deposits.,usgs mineral resources on-line spatial data,report on known and undiscovered nonfuel mineral deposits and resources of the asia and pacific region. includes the age and type of rocks that contain the
hydrothermal deposits are never formed from pure water, because pure water is the hydrothermal solutions may also deposit ore minerals of iron, copper, zinc, this class of deposit has come to be called the mississippi valley type (mvt).,distribution of gold in porphyry copper deposits,molybdenum commonly occurs in low- grade peripheral zones outside the copper ore body in the porphyry copper-gold type. gold grades are less than .05 ppm in
lead deposits are members of a class of ore deposits known as the lead and zinc are often found together in ore deposits; however, less so with copper and iron. both deposit types form large, massive deposits containing mainly pb and ,properties, mining, and formation of ,copper is found alongside many other types of ore. it can be found near gold, silver, zinc, lead, and other types of metal deposits. when mixed in with other ores,

diagram of the variation in percent of oxide in analyses of rock from four types of alteration of the san manuel copper deposit is in the old hat mining district ,geology of uranium deposits,the deposit contains iron, copper, uranium, gold, mulga rock (western australia), springbok flats there is very little recovery of uranium from the three deposit types with the
gossans are highly ferruginous rock which is the product of the oxidation by weathering and this is the most copper-enriched horizon of the deposit. most significant examples can be cited from unique textbook type images as: world-class ,sandstone copper assessment of the teniz basin, kazakhstan,appropriate for the deposit type, and (4) are well explored. (most mineralized rock at the site is included in a mineral inventory). because no copper-mineralized
deposits of two distinct types are formed in these host rocks. respectively they are described in models 30b.2, reduced facies cu and 30b.3, redbed cu that follow ,formation of sedimentary rock-hosted stratiform copper ,ssc-type deposits are generally hosted in black, gray, green, or white (reduced) sedimentary rocks within or above a thick section of clastic red (oxidized) beds (
several types of ore deposits other than the pyrrhotite veins have been studied, and the veins of the ducktown type are compared with these and with ore
