Interrogating the role of magmatism, tectonics, crustal growth and basin redox in controlling localization, genesis, tonnage, and grade of exhalative base and precious metal mineralization along evolving continental margins

火山成因块状硫化物（VMS）矿床是加拿大和全球经济的重要金属（锌、铅、铜、金、银）来源。尽管经过数千年的开采和数十年的研究，仍然存在一些基本问题，即是什么控制了矿化的规模（吨位）和丰度（品位）。特别是，高价值矿床往往很大和（或）金属品位高，但对品位和吨位的控制并不完全了解。该研究计划将侧重于加拿大科迪勒拉山脉和阿巴拉契亚山脉带的岩石，研究与VMS矿床相关的岩石和矿物成分，作为存款吨位和品位的函数，以评估岩浆在存款成因中的潜在作用，并评估过去沃茨中的氧含量在存款定位和金属丰度中的作用。拟议的研究将创造新的知识，这将有助于科学，但也提供矿产勘探参数，可能有助于地球科学

Volcanogenic massive sulfide (VMS) deposits are important sources of metals (zinc, lead, copper, gold, silver) to the Canadian and global economy. Despite millennia of mining, and decades studying these deposits, there are still fundamental questions that remain regarding what controls the size (tonnage) and abundance (grade) of mineralization. In particular, high-value deposits are often large and/or have high grades of metal, yet the controls on grade and tonnage are not fully understood. This research program will focus on rocks in the Canadian Cordilleran and Appalachian mountain belts, looking at the compositions of rocks and minerals associated with VMS deposits as a function of deposit tonnage and grade to evaluate the potential role that magmas play in deposit genesis, and to evaluate the role that the oxygen content of ocean waters in the past has played in deposit localization and metal abundance. The proposed research will create new knowledge that will contribute scientifically, but also provide mineral exploration parameters that may help geoscience
