Qulong, the first large porphyry Cu–Mo deposit found in China so far, is situated in the southern part of the Lhasa terrane (latitude 29°37′ N, longitude 91°36′ E), about 50 km east of Lhasa ().The Lhasa terrane, bounded by the Indus–Yarlung suture (IYS) and Bangong–Nujiang suture (BNS) (Fig. 1B), is composed mainly of mid-Proterozoic and early Cambrian orthogneiss basement, and Cited by: Porphyry copper deposits defined in this way gradually merge with porphyry gold deposits, as the Cu/Au ratio declines. With the prominent exception of Grasberg, most porphyry copper–gold deposits have higher copper grades and lower total ore tonnages than porphyry copper–molybdenum deposits Kesler, , Kirkham and Sinclair, , Long Cited by:

Assay results received from an initial nine hole (5, metre) diamond drill program . 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.

Berg History The Berg Property is a copper-molybdenum-silver deposit located in west-central British Columbia, Canada, approximately 50 miles southwest of Houston, British Columbia, and 15 miles northwest of the currently operating Huckleberry Mine.

Get this from a library. Berg porphyry copper-molybdenum deposit: geologic setting, mineralization, zoning, and pyrite geochemistry. [Andrejs Panteleyev].

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.

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. Here let’s understand the geology of porphyries and iron oxide copper gold deposits or IOCG as they are known.

These are somewhat the giants of the ore deposits world. As a mining interested Berg Porphyry Copper-Molybdenum Deposit book, the geology of porphyry copper deposits is vital to your education. Now in the first Exploration Geology Course I discussed how because our current mining technology all the metals that we use.

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.

Berg copper-molybdenum deposit is in mountainous terrain of the Tahtsa Range in west-central British Columbia. It is a type example of Lowell and Guilbert's () model of porphyry copper deposits. The deposit is in thermally metamorphosed and hydrothermally altered Middle Jurassic volcanic rocks and Tertiary quartz diorite adjacent to a weakly mineralized Eocene stock.

The stock is about. The Berg porphyry copper-molybdenum deposit is in the Tahtsa mountain ranges, approximately 84 km southwest of Houston, British Columbia.

It is localized in and adjacent to one of several mineralized ca. m.y.-old quartz monzonite intrusions in the by: 4. Molybdenum is obtained from two different types of mines: primary mines and by-product mines.

By-product mines are most commonly referred to as Copper-Molybdenum ore bodies, while ‘primary. Porphyry is a textural term for an igneous rock consisting of large-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate rich, generally aphanitic matrix or larger crystals are called its non-geologic, traditional use, the term porphyry refers to the purple-red form of this stone, valued for its appearance.

Sulfur (S) species, in particular sulfide (H 2 S, HS- S 2-), are fundamental in the formation of porphyry deposits, and it can be speculated that sulfur partitioning coincides with molybdenum sequestration.

Based on this assumption, we developed a series of different scenarios for coupled Mo and S isotope fractionation, which resulted in Mo Author: Joshua R.

Peterson, Gail Lee Arnold, Benjamin Brunner, Philip C. Goodell. Erdenet, a site known since prehistoric time, was recognized as a major copper deposit inintensively explored during the s, and began production in Elongate (NW SE) mineralized zone in Selenge Intrusive Complex.

The mineral resource assessment discussed in this report considers two deposit types: (1) porphyry or stockwork deposits of copper. and molybdenum (referred to generally in this report as porphyry deposits) and (2) skarn deposits of tungsten, iron, gold, copper, and silver.

Combining copper and molybenum porphyry deposits into a single. Optimum conditions for development of giant porphyry copper deposits Porphyry Copper Deposit Model porphyry copper deposits generally form in the upper crust (less than 5–km depth) in tectonically active convergent margins and commonly in areas that are elevated and(or) subject to high uplift rates.
