Geology of the Maricunga Belt. The Maricunga belt, located in northern Chile about 700 km north of Santiago (Figs. 1, 2), is a metallogenic province of Miocene age that contains numerous gold, silver, and cop per deposits of porphyry and epithermal character (Vila and Sillitoe, 1991).
Mar 13, 2017At El Laco in the upper levels of the large magnetite apatite ore body at Laco Sur, two massive magnetite ore samples were collected (ELL 14 04 and ELL 14 05). In the lower levels of the Laco Sur ore body (at approximately 4650 m elevation), a magnetite vein from a feeder structure was sampled (ELL 14 06).
Iron oxide copper gold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) abundant magnetite and/or hematite, (4) Fe oxides with Fe/Ti greater than those in most igneous rocks, and (5) no clear spatial associations

Santo Domingo is a copper iron gold mine located near the town of Diego de Almagro in Region III of Chile. Owned by Capstone (70%) and Korea Resources Corporation (30%), it has the potential to be a long life copper and iron ore producer. The pre feasibility study was completed in 2008 by Ausenco

Mar 13, 2017To address this controversy, we have analyzed the trace element content of magnetite from precisely known geographic locations and geologic environments from the Precambrian magnetite apatite ore and host rocks in Kiruna, Sweden, and the Pliocene Holocene El Laco volcano in the Atacama desert of Chile.
Descriptions of major ore deposits world wide. El Algarrobo in the Huasco Valley in Chile's 3rd Region is one of the seven large (>100 Mt of high grade ore) iron oxide deposits magnetite apatite deposits within the 1000 km long Cretaceous Chilean Iron Belt which lies within the Coastal Cordillera of northern Chile, closely associated with the Atacama Fault Zone.
The Maricunga belt is a region of numerous gold silver copper prospects and deposits in the high Andes of northern Chile (Vila and Sillitoe, 1991; Fig. 1). Zones of hydrother mally altered rocks give rise to strong color anomalies de tectable by satellite imagery and aerial photography (Fig. 2).

1 Ore Deposits ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G. McQueen CRC LEME, Australian National University, Canberra, ACT 0200 and School of REHS, University of Canberra, ACT 2601. INTRODUCTION Ore deposits are crustal concentrations of useful elements that can be exploited at a prot. Like all crustal rocks, they consist of minerals
Silica bearing magnetite was recognized in the Copiap Nordeste prospect as the first documented occurrence in Chilean iron oxidecoppergold (IOCG) deposits. The SiO2 rich magnetite termed silician magnetite occurs in early calcic to potassic alteration zones as orderly oscillatory layers in polyhedral magnetite and as isolated discrete grains, displaying perceptible optical differences
gets for additional gold bearing lode deposits or related placer occurrences. INTRODUCTION Ore deposits are commonly intimately associated with plutonic bodies of all ages and tectonic settings. Studies of magmatic hydrothermal systems have led to two contrasting explanations for the association of ore deposits with plutonic rocks.
IOCG Iron Oxide Copper Gold Ore Deposits. IOCG Iron Oxide Copper Gold Ore Deposits ore is often striking to look at and it is often very red from the hematite content, blue from bornite or yellow green from various uranium oxides. You can see some of the oars from the Olympic Dam in this photo.
Analysis of 55 porphyry copper deposits demonstrates a continuum between porphyry copper gold deposits emplaced at a median depth of 1 km, with a median size of 160 million metric tons of copper ore and a median content of 2.6% magnetite in the potassic alteration zone, and porphyry copper molybdenum deposits emplaced at a median depth of 3.6 km,
Interest in Chiles Iron Deposits Renewed with Application of Modern Exploration Techniques. Hydrothermal magnetite ore deposition was accompanied by the pervasive occurrence of actinolite. In many deposits, movement on the north south trending Atacama Fault Zone was concurrent with ore deposition and intra mineral dikes.
