Although studies have proposed that iron oxide-apatite (IOA) deposits may represent the deeper roots of some Andean oxide copper-gold (IOCG) systems, their genetic links remain obscure and controversial. A key question when considering an integrated model is whether a magmatic-hydrothermal fluid precipitates massive magnetite will continue transporting significant amounts dissolved Fe, Cu, Au after IOA precipitation. Here we provide new geochemical data for accessory pyrite from Los...
Abstract The genetic link between magmas and ore deposit formation is well documented by studies of fossil hydrothermal systems associated with magmatic intrusions at depth. However, the role explosive volcanic processes as active agents mineralization remains unexplored owing to fact that metals volatiles are released into atmosphere during eruption arc volcanoes. Here, we draw on observations uniquely preserved El Laco iron in Central Andes shed new light metallogenic volcanism operates a...

Arsenic-rich (arsenian) pyrite can contain up to tens of thousands parts per million (ppm) toxic heavy metals such as Hg, Tl, and Cd, although few data are available on their solid solubility behavior. When a compilation Cd analyses from different environments plotted along with As in M(Hg, Cd)-As log-log space, the resulting wedge-shaped distribution points suggests that aforementioned is strongly dependent concentration pyrite. The limits Hg arsenian pyrite—i.e., upper limit zone...
A new mode of arsenic incorporation into arsenian pyrite has been discovered. Electron microprobe analyses and elemental maps from Pueblo Viejo, Dominican Republic, show that its chemical composition varies (Fe0.998As0.003)1.001S2 to (Fe0.963As0.050Cu0.003Ag0.001)1.017S2 is inversely correlated with Fe. High-resolution transmission electron microscopy (HRTEM) images some in this present as nanoscale inclusions amorphous As- Fe-S a matrix pyrite. The display negative facets cubic or...
Iron oxide-copper-gold (IOCG) deposits are a globally important source of copper, gold and critical commodities. Despite their relevance, IOCG remain an ill-defined clan, with range characteristics that has complicated development the general genetic model. Here we focus on Candelaria deposit in Chile reveal by using micro-textural compositional variations actinolite, common alteration mineral found many deposits, can constrain evolution these systems. We demonstrate formed superposition at...
