The high variability of in-situ magnetic properties presented in the Los Pelambres deposit has also been characteristic of other porphyry copper deposits in Chile (e.g., Chuquicamata and El Teniente).
2015-4-19 Northern Chile has some of the largest copper (± gold ± iron) deposits in the world. These copper deposits formed from a combination of factors, but are generally associated with intrusive-extrusive magmatism and tectonic activity on the western boundary of the South American plate (Davidson, 1987; Camus, 1990; Sillitoe and Perelló, 2005).
A magnetic survey was made in Sand Canyon, which is in the northwestern part of the San Gabriel Mountains, the object being to locate possible placer deposits. The bedrock in this area is an iron rich igneous rock which has been intruded by numerous dikes. The stream gravels consist of large boulders interspersed with highly magnetic sands.
2018-1-5 El Romeral is one of the largest iron oxide-apatite (IOA) deposits in the Coastal Cordillera of northern Chile. The Cerro Principal magnetite ore body at El Romeral comprises massive magnetite intergrown with actinolite, with minor apatite, scapolite, and sulfides (pyrite ± chalcopyrite). Several generations of magnetite were identified by using a combination of optical and electron
2018-6-11 Geophysical exploration of ironsand deposits has in the past been limited to ground magnetic surveys, designed to assess the lateral extent of near-surface magnetic sands; the data wer e not used to obtain quantitativ estimates of or reserves. A survey by Coss (1959) in New South Wales, Australia, indicated that magnetic anomalies occur over heavy
