Stable Isotopic Studies of the Voisey's Bay Copper-Nickel-Cobalt Deposit, Labrador, Canada: The Role of Externally-Derived Sulfur in Ore Genesis

0086538 Ripley该补助金为印第安纳州大学的艾德·里普利和一名研究生提供支持，对与加拿大拉布拉多的Voisey's Bay块状硫化物存款有关的岩石进行稳定同位素、微量元素和成分分析。 Voisey's Bay存款是当今世界上最大的经济上可行的镍矿床之一。PI与Tony Naldrett（多伦多大学）合作进行的先前初步研究表明，尽管硫化物饱和，但该存款的矿化似乎是由围岩对岩浆侵入的污染造成的。 尽管如此，一个吸烟gun尚未found.This研究将扩大以前的研究，增加高分辨率的稳定同位素分析硫，氧和碳从多个全岩和矿物分离样品取自低硫县岩石和未矿化和矿化部分的存款，以阐明硫的来源负责硫化物饱和度内的存款。

0086538RipleyThis grant provides support to Ed Ripley and a graduate student at the University of Indiana to conduct stable isotopic, trace elemental and compositional analysis of rocks associated with the Voisey's Bay massive sulfide deposit in Labrador, Canada. The Voisey's Bay deposit is one of the largest economically viable nickel deposits in the world today. Previous preliminary studies by the PI in collaboration with Tony Naldrett (Univ. Toronto) have indicated that mineralization of this deposit, though sulfide saturation, appears to have been caused by contamination of the magmatic intrusion by country rocks. Nonetheless, a smoking gun has not yet been found. This study would expand on previous research by adding high resolution stable isotopic analyses of sulfur, oxygen and carbon from multiple whole rock and mineral separate samples taken from the low-sulfur county rock and unmineralized and mineralized portions of the deposit to elucidate the source of sulfur responsible for sulfide saturation within the deposit.
