The Erdenet porphyry copper-molybdenum deposit in central Mongolia is hosted in the Selenge Intrusive Geochemistry of granitoids and altered rocks of the Erdenet porphyry copper-molybdenum deposit, central Mongolia Prolonged discrete oriented development of ore-magmatic systems in copper-molybdenum formation. Geology and Geophysics Cited by: 1. This report is one of several in the series that assess the mineral resources of the Dillon quadrangle. For the purpose of the assessment, mineral deposits in the quadrangle that are either known or suspected from a knowledge of the geologic setting have been grou~d into 30 deposit types on the basis of mineralogy, commodity, or structural or depositional setting.
The Cerro la Mina Au (Cu-Mo) porphyry-high sulfidation prospect is located in Chiapas State, southeastern Mexico, outside of the major metallogenic provinces of Mexico. The prospect is hosted by Pleistocene alkaline volcanic rocks of the Chiapanecan volcanic arc that formed in a complex triple-junction tectonic setting. Cerro la Mina’s stratigraphy comprises pyroclastic flows that were Cited by: 3. The North Area is a porphyry copper-molybdenum system in the northern part of the Ruby Project, which is % owned by the O.T. Mining Corp. O.T. has conducted surface geochemistry, geophysics, and limited drilling in the porphyry system over the past 3 years as funding allowed.
The granodiorite porphyry is petrologically similar to porphyry copper-related intrusions from island arc and continental margin settings, which form a group with initial 87 Sr/ 86 Sr ratios of less than 0. , representing magmas produced in tectonic environments lacking any important component of old (i. e. Precambrian) continental by: 8. 1. Introduction. Although porphyry copper deposits are usually thought to form in island-arc and continental arc settings (Sillitoe, , Mitchell, , Cooke et al., ), they can also occur in post-collisional extensional settings (Hou et al., a, Hou et al., , Hou et al., , Hou et al., , Hou et al., ).The Gangdese Porphyry Copper Belt (GPCB) is a significant but Cited by:

Dillon. Climax-type porphyry molybdenum deposits are extremely rare (this model documents 13 deposits on Earth), especially compared to the hundreds of porphyry copper deposits that exist worldwide.
As defined here, the deposits are restricted to the Late Cretaceous and Tertiary and to western North Size: 1MB. Other articles where Porphyry molybdenum deposit is discussed: mineral deposit: Porphyry deposits: deposits (and their close relatives, porphyry molybdenum deposits) contain disseminated mineralization, meaning that a large volume of shattered rock contains a ramifying network of tiny quartz veins, spaced only a few centimetres apart, in which grains of the copper ore minerals chalcopyrite.
Porphyry copper deposits are copper orebodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name.
In later stages, circulating meteoric fluids may interact with the magmatic. Porphyry copper and porphyry molybdenum deposits are the world’s largest sources of copper (~60%) and molybdenum (~95%) and commonly contain s of million metric tons (Mt) to >20 billion metric tons (Gt) of ore (Seedorff et al., ; Sinclair, ; Singer et al., ; John et al., ; Sillitoe, ; Taylor et al., ).These deposits formed from large magmatic-hydrothermal systems.

The Poplar copper-molybdenum porphyry deposit, 50 kilometres south-southwest of Houston, is centred near 54 degrees 01 minute north and degrees 50 minutes west. Pebble is a giant, classic calc-alkalic porphyry copper-gold-molybdenum deposit.
It is composed of the East and West zones which represent two coeval hydrothermal centers within a single system. The West zone extends from surface to ~m depth and is centered on four small granodiorite plutons emplaced into flysch, diorite, and granodiorite.

Chile, China, and the United States also held about 83% of the estimated Mt of world molybdenum reserves,” according to the United States Geological Survey Molybdenum Minerals Year Book. Porphyry deposits are usually thought to form from subduction-related calc-alkaline magmas in magmatic arc settings, although some porphyry deposits also occur in post-collisional extensional settings.
The post-collisional deposits remain poorly understood. Here we describe the igneous geology, alteration mineralogy and mineralization history of Qulong, a newly-discovered porphyry Cu-Mo.
Porphyry copper and molybdenum deposits in west-central British Columbia are associated with plutons of Late Cretaceous and Tertiary age which intrude Mesozoic volcanic and sedimentary rocks of the Intermontane Tectonic Belt.
The porphyry deposits are contained in an area bounded on the west by granitic rocks of the Coast Plutonic Complex, and on the east and southeast by a belt containing Cited by: 5.
Geology is the best tool in porphyry exploration. Besides the best University in your country, look through company reports, aid programmes. If you are checking out a virgin province, look for references to large areas of K silicate and sericite alteration, silicification, quartz veining and stockworks.
The Oyu Tolgoi porphyry copper-gold-molybdenum deposits are located in the South Gobi Desert of Mongolia (43°01′40″N, °51′34″E), approximately km due south of the capital, Ulaanbaatar, and 80 km north of the Chinese border.
