Sillitoe, Society of Economic Geologists, Denver, Special Publication Iron oxide-copper-gold (IOCG) deposits, defined primarily by their elevated magnetite and/or hematite contents, constitute a broad, ill-defined clan related to a variety of tectono-magmatic settings. The youngest and, therefore, most readily understandable IOCG belt is located in the Coastal Cordillera of northern Chile and southern Peru, where it is part of a volcano-plutonic arc of Jurassic Cited by:
The Andean IOCG belt is a major contributor to Chile’s copper production. Deposits range in size from to Million tonnes with grades varying from to 10 percent copper and gold values generally below grams per tonne (Sillitoe, ). Andean orogenesis commenced in the Late Triassic to Early Jurassic, with subduction of the Nazca plate beneath South America. The major Central Andean copper deposits of Chile and Peru, together accounting for over 90% of total Andean copper resource, were emplaced over at least three major epochs of magmatism during the Cenozoic (Sillitoe, ).Cited by:

Andean Copper Deposits: New Discoveries, Mineralization, Styles and Metallogeny Paperback – January 1, by Francisco; Richard M. Sillitoe; Richard Peterson; Patricia Sheahan Author: Francisco; Richard M. Sillitoe; Richard Peterson; Patricia Sheahan (Series Editor) Camus.
The copper deposits of Perú consist of porphyry Cu±Mo, Au, Ag, breccia pipe Cu-Mo, enargite vein and replacement Cu±Au, Ag, Zn, Pb, calcic skarn Cu±Fe, Au, Zn, amphibolitic skarn Cu±Fe, volcanogenic massive sulfide Cu-Zn, vein and manto Cu±Ag, Pb, Zn, Sn, W, and sandstone (“red bed”) Cu types.
Numerous studies of individual Andean Cu deposits have been conducted during the last century, with those by Lindgren and Bastin () and Gustafson and Hunt () at the El Teniente and El Salvador porphyry Cu deposits, respectively, being arguably the truly ground-breaking studies. Andean copper deposits: new discoveries, mineralization, styles and metallogeny is the fifth in the Special Publication Series for the Society of Economic Geologists.
We have two other suc cessful series, Reviews in Economic Geology and our Guidebook Series. The Society of Economic Geologists sponsored a symposium in Chile inCamus and. Additional Physical Format: Online version: Andean copper deposits.

The present volume Stratabound Ore Deposits in the Andes has its roots in an international seminar on stratabound ore deposits which took place in September in Cusco, Peru, sponsored by Multi ciencias (Peru) and UNESCO. In many respects, the most unusual and least well understood deposits of the region are the magnetite deposits of El Laco, in northern Chile.
Long considered a type-example of magmatic differentiation involving an immiscible oxide melt, the El Laco deposits have many enigmatic features.

The formermost is host to higher-grades of hypogene mineralisation. The tourmaline breccia and dacite dikes host. During the Andean Orogeny the extent of magmatism and the corresponding metallogenic provinces were influenced by subducted plate segmentation and by continental margin basement tectonics.
In addition, the lithologic nature of the host rocks played an important role in determining the types of copper deposits formed. The small dots along the western South American margin which appear through time correspond to porphyry copper-gold deposits. Mineralization in the central Altiplano-Puna region (21°°S) formed above a formerly flat subduction zone as volcanism was reinitiating.
Thus, hydration and crustal thickening associated with transitions in and out of flat-slab subduction conditions are fundamental controls.
The proposed linkage of central Andean and probably some other IOCG deposits to oxidised dioritic magmas may be compared with the well-documented dependency of several other magmatic-hydrothermal deposit types on igneous petrochemistry.

These deposits form a limited belt that is not apparently continuous to the north or south. Metallurgy in pre-Columbian America is the extraction, purification and alloying of metals and metal crafting by Indigenous peoples of the Americas prior to European contact in the late 15th century.
Indigenous Americans have been using native metals from ancient times, with recent finds of gold artifacts in the Andean region dated to – BCE, and North American copper finds dated to.

Porphyry copper deposits are copper ore bodies 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.LITERATURE COLLECTION - Part 1, CHILE, Overview.
