Veins and lodes consist of aggregates of minerals containing base and/or precious metals, uranium, etc which have been deposited in fractures in the enclosing rock mass, or have replaced the rock immediately adjacent to the fracture zinc, silver, copper deposits in limestone, generally occur in more or less flat-lying (mantos) clusters. Introduction a magmatic arc hydrothermal system is a class of hydrothermal systems that interlink major styles of precious metal and base metal deposits these deposits include well known types like epithermal gold-silver, (low sulfidation and high sulfidation), polymetallic silver-gold, sediment hosted replacement gold (carlin-type), carbonate gold-silver base metal, porphyry copper gold. Unlike other metals, gold has not been acquired by mining until modern times it was traditionally found in placer deposits in rivers, which form easily since the density of gold, 193, is much higher than the density of gangue, which is about 26. The components of massive sulphides include iron sulphide (pyrite), copper sulphide (chalcopyrite), and zinc sulphide (sphalerite), as well as sulphides of other metals such as gold and silver the relatively high content of precious metals makes the massive sulphides promising for ocean mining. Silver as a native element mineral silver is rarely found as a native element mineral when found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver mineralsunlike gold, it is rarely found in significant amounts in placer deposits.
Mineral deposit - hydrothermal solution: hydrothermal mineral deposits are those in which hot water serves as a concentrating, transporting, and depositing agent they are the most numerous of all classes of deposit hydrothermal deposits are never formed from pure water, because pure water is a poor solvent of most ore minerals rather, they are formed by hot brines, making it more. Hydrothermal deposits rich in copper, lead, zinc, gold, silver, molybdenum, tin, mercury, and cobalt form from hot solutions that circulate through fractured country rock the solutions come from nearby intrusions or heated meteoric water. The hydrothermal fluid near okinawa belongs to the same type of volcano as the hishikari gold mine, in kagoshima prefecture, southwestern japan, known for generating high-grade gold.
Many hydrothermal ore deposits have been formed by once active—and in a few cases still active—geothermal systems gold is one more legacy of volcanism read more. Binq mining mining equipment posted at:june 9, 2013[ 45 - 3529 ratings] many hydrothermal mineral deposits of copper, gold, silver, many hydrothermal mineral deposits of copper, gold, silver, and other metals have been found in the countries bordering on the pacific ocean. Many hydrothermal mineral deposits of copper gold silver and other metals have been found in the countries bordering the pacific ocean can you offer an explanation. 421 source of metals some types of hydrothermal deposits are directly linked to plutonic rocks, usually a class that yields about 50% of the world’s copper for most other types of hydrothermal deposit, however, a link to magmas cannot be demonstrated and in tungsten and in lesser quantities gold and silver vms deposits on basaltic.
Copper deposits, leading to the conclusion that such a system might be present at depth breccia pipes are common in porphyry systems, though classic porphyry-style mineralization has not yet been found in all districts where breccia pipes are known in which metals are precipitated from hydrothermal fluids of dominantly magmatic origin. Copper is found alongside many other types of ore it can be found near gold, silver, zinc, lead, and other types of metal deposits copper is also commonly found in the oxidized zones of mineral deposits and in basalt cavities that have been in contact with hydrothermal veins the presence of volcanoes in a region is often a good indicator. Copper is also found in many other countries throughout the world perú, poland, méxico, zaire, zambia and papua-new guinea have historically been among the leading producers, and although african production has fallen sharply in recent years owing to political difficulties, large untapped resources remain. Hydrothermal mineral deposits may contain a vast range of different mineral's, including native elements, sulphides, oxides, halides, carbonates, sulphates, phosphates and silicates the mineralogy of any one deposit reflects a variety of things, the two most important are.
Vms deposits are associated with a number of other mineral deposit types (cox and singer, 1986) some vms volcanic-associated massive sulfide deposits are among the most likely of all deposit types to have associated can contain anomalous concentrations of gold, silver, and cobalt deposits associated with felsic volcanic and. Many hydrothermal mineral deposits of copper, gold, silver, and other metals have been found in the countries bordering the pacific ocean can you offer an explanation for this remarkable concentration. Many other metals such as silver, cobalt, manganese, nickel and pge may occur in economic concentrations zoned hydrothermal alteration characterises almost all iocg deposits various alteration patterns depend. Because of their large volume, porphyry orebodies can be economic from copper concentrations as low as 015% copper and can have economic amounts of by-products such as molybdenum, silver and gold in some mines, those metals are the main product.
Hydrothermal mineral deposits, on the other hand, are neither common nor very large compared to other geologic features most deposits of gold, silver, copper, lead and zinc, mercury, antimony and molybdenum come under this class most deposits of minor metals and many non-metallic minerals are formed by this process many ore deposits. High concentrations of cu and other ore-forming elements have been found in fluid inclusions from many deposits (audetat et al, 1998, baker et al, 2004, williams-jones and heinrich, 2008) investigations on coexisting single brine and vapor inclusions have demonstrated that partitioning has taken place between saline fluid and vapor for.
Best answer: quite a range of confusing answers there let's get back to basics and look at what defines a mineral and a metal a mineral is a naturally occurring, inorganic, crystalline substance we know of over 5000 minerals a metal is an element, compound, or alloy which conducts electricity a mineral. Complex copper minerals –copper in combination with: iron, nickel, cobalt, lead, zinc or silver and other elements volcanogenic massive sulphide deposits these deposits have been found actively forming at a temperature of 350°c. Some deposits have such high concentrations of gold that they may be considered gold deposits rather than copper deposits others have barely any gold at all but may have plenty of molybdenum large size, low grade – porphyries typically have 100 million to 5 billion tonnes of ore with a lower grade (02% to 1% copper. Most deposits of gold, silver, copper, lead and zinc, mercury, antimony and molybdenum come under this class most deposits of minor metals and many non-metallic minerals are formed by this process cr, ti, v, zr, u, ce, ta and pt are absent in deposits of this class.
