Collaborative Research: Geochemical Evolution of Magmatic-Hydrothermal Systems: Insights From Deep Drilling of the Giant Butte Base Metal Ore Deposits

9614683迪勒斯铜(铜)、钼(钼)矿床是以花岗斑岩侵入体为中心的大型岩浆-热液系统的产物。热液围岩蚀变、矿脉形成和矿石硫化物沉淀是裂隙集中脱气或花岗岩基岩产生含有溶解盐、金属、硫和酸的水溶液的结果。目前这种类型的成矿模型需要根据最近的研究结果进行重新评估。这项建议的主要目标是利用一项综合的地球化学研究来提高对斑岩型贱金属矿床的了解，该研究的重点是从到达巨型巴特矿床深部的钻芯中提取的样品。这些数据，加上目前可获得的更高级别矿床的信息，应该会提供这个巨大的世界级贱金属热液系统的特殊三维视图。

9614683 Dilles Copper (Cu) and molybdenum (Mo) ore deposits can be formed as products of giant magmatic-hydrothermal systems centered on granitic porphyry intrusions. Hydrothermal wall-rock alteration, vein formation, and ore sulfide precipitation form as the result of fracture-focused degassing or granitic batholiths to produce aqueous fluids containing dissolved salts, metals, sulfur, and acids. The current models for mineralization of this type need to be re-evaluated based on recent research results. This proposal has as a primary goal to improve the understanding of porphyry-type base metal deposits by using an integrated geochemical study that focuses on samples derived from drill cores that reached deep portions of the giant Butte deposit. These data together with the information that is currently available for higher levels of the deposit, should provide an exceptional three-dimensional view of this huge, world-class, base metal hydrothermal system.
