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

9614683 Dilles铜（Cu）、钼（Mo）矿床是以花岗斑岩侵入体为中心的巨型岩浆-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的形成是由于火山岩集中脱气或花岗岩基产生含有溶解盐、金属、硫和酸的含水流体。 需要根据最近的研究结果重新评估目前的这类成矿模式。 这项建议的主要目标是通过综合地球化学研究，重点是从钻到巨大的Butte存款深部的岩心中提取的样品，提高对斑岩型贱金属矿床的认识。 这些数据与目前可获得的存款更高层次的信息一起，应该提供这个巨大的，世界级的，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.
