Porphyry Copper Deposit Density Article (PDF Available) in Economic Geology (3) July with 1, Reads How we measure 'reads'. copper deposits are the most important source for copper, accounting for more than 60 percent of the annual world copper production and approximately 65 percent of the known total copper resource. Since , more than 95 percent of the U. S. copper production has been derived from porphyry copper Size: KB.

On a cool sunny day in May, I drove New Mexico State Road down the valley of the evocative Dry Cimarron River. For hours I saw no one, aside from ghostly travelers conjured up by “Cimarron”—dusty men on wild-eyed horses, traders with heavily-loaded mules, armed banditos lurking behind the rocks, and gaunt men of God driven by the other-worldly light in their eyes. Porphyry Cu–(Au)–(Mo) deposits are one of the most important economic mineral associations (Sillitoe, , Sillitoe, , Hedenquist et al., , Heinrich et al., , Cooke et al., ), hosting most of the world’s copper resources (Ulrich et al., , Halter et al., ).More than 90% of the porphyry Cu deposits in the world are distributed along convergent margins ().Cited by:

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.
RV: Deposits of the Revett model are in thick beds of reduced (pyritic) quartzite (properly, metasandstone) near pre-ore redox fronts (Hayes and Einaudi, ; Hayes, ). Orebodies may be stacked, especially near faults (Balla, ). Copper is not associated with solid organic matter in Revett deposits, but copper may have been depositedFile Size: KB.

Copper 3 5Stockwork: network of many cross-cutting veins. 6Disseminated: small, fine-grained particles of ore mineral dispersed through a rock. 7Intrusion: a body of igneous rock emplaced into pre-existing rocks. 8Stratabound: an ore deposit that is confined to a single sedimentary bed or horizon.
9Sedimentary: rocks formed from material derived from other rocks by weathering. The Sheep Pen Sandstone Formation is a Mesozoic geologic formation in the United States.
Fossil theropod tracks have been reported from the formation. See also. List of dinosaur-bearing rock formations. List of stratigraphic units with theropod tracks; Footnotes Type: Geological formation.
Porphyry ore deposits are the source of much of the copper, molybdenum, gold and silver used by humans. Porphyry ore typically forms in magmatic arcs above subduction zones.

14 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.
Porphyry copper deposits account for 75% of natural copper worldwide. They are formed by magma chambers situated between 10 and 15 km beneath Earth’s surface.
At this depth, the magma heats to around °C but when it comes into contact with the surrounding rock, it cools and crystallises. Sedimentary Copper Deposits Investing News Network - May 12th, Not all metal deposits have igneous origins- sedimentary deposits can also be a valuable source of many metals, including copper.
Copper is a moderately incompatible chalcophile element. Its behavior is strongly controlled by sulfides. The speciation of sulfur is controlled by oxygen fugacity. Therefore, porphyry Cu deposits are usually oxidized (with oxygen fugacities > ΔFMQ +2) (Mungall ; Sun et al.
The problem is that while most of the magmas at convergent margins are highly oxidized, porphyry Cu Cited by: chalcosis len'tis a cataract caused by excessive intraocular copper.

search for new ore deposits. The relationships of many metallic deposits to plate boundaries has become increasingly clear, the best example perhaps being that of porphyry copper deposits.
Other plate boundary relationships range through various metallic deposits to concentrations of .Descriptions of major ore deposits world wide. Udokan is a major sediment hosted copper deposit located in Zabaykal'skiy Kray, northeast of Lake Baikal, in the Transbaikal region of eastern Russia, and ~ km NNE of Chita, the capital of the Krai.
The deposit is ~30 km south of Chara railway station of the Baikal-Amur Mainline (BAM) loop of the Trans-Siberian Railway, and adjacent to the.Copper toxicity in sheep is more often a problem of nutritional management than it is excess copper intake.
The purpose of this paper is to look at such factors as nutrient interactions, animal management, and environmental conditions that may increase the risk of copper toxicity and how the sheep producer can minimize these risks.
