The porphyry copper deposit at El Salvador, Chile ...
The formation of the porphyry copper deposit at El Salvador culminated volcanic activity in the Indio Muerto district. Host rocks for the ore are Cretaceous andesitic flows and sedimentary rocks overlain unconformably by lower Tertiary volcanics. Early rhyolite domes, formed about 50 m.y. ago and roughly contemporaneous with voluminous rhyolitic and andesitic volcanics, were followed by ...Cited by: 867

Chronology of Exotic Mineralization at El Salvador, Chile ...
01/03/2001 0183 32At the El Salvador porphyry copper deposit in northern Chile the majority of the exotic ore comprised a mixture of copperbearing manganese oxyhydrates termed quotcopper wad.quot Xray diffraction, scanning electron microscopy, and electron probe microanalysis show that the copper wad is composed of copperbearing cryptomelane K 12 Mn 3 Mn 4 8 O 16 x H 2 O and birnessite K 0.
Sulfur isotopes in the porphyry copper deposit at El ...
Sulfur isotope analyses have been performed on 64 monomineralic concentrates from 37 samples that are representative of mineralization in time and space at El Salvador. The hypogene sulfates mean 10.7ppm range 7.3 to 17.0ppm are enriched in 34 S relative to supergene sulfates 0.7ppmgt 4.6 to 3.6ppm and to hypogene sulfides 3.0ppm 10.1 to 0.3ppm .

The study assesses the ecological impact caused by the El Salvador untreated 19751990 and treated 19911994 copper mine tailings on rocky intertidal communities in and around the dumping site at Caleta Palito, northern Chile. Ecological changes are monitored for 16 years in polluted and unpolluted sites within a geographical area of 90 km. Copper concentration levels in water and the ...
