Magmatic, tectonic, sedimentary and hydrothermal evolution of cordilleran rifts

火山-含块状硫化物（VMS）、火山-沉积物-含块状硫化物（VSMS）和沉积物-含块状硫化物（SEDEX）矿床是加拿大锌、铅、铜、银和金的重要来源。这些沉积物通常与构造板块相对分离的环境有关，这种环境被称为“裂谷”。裂谷环境通常与岩浆、火山和沉积岩的沉积有关，其中大部分是在古代海洋和沉积盆地的水下形成的。此外，被加热的富含金属的流体（称为“热液流体”）在裂缝内的岩石包裹层中循环，最终形成VMS、VSMS和SEDEX矿床。该研究基金旨在研究育空地区和不列颠哥伦比亚省北部（+/-NWT）科迪勒兰山脉系统岩石中与这些裂缝相关的岩浆作用、沉积岩和热液流体历史之间的相互关系。研究的主要目的是了解裂谷环境中岩浆活动类型的时间变化以及沉积岩的沉积历史。这些研究将增加我们对裂谷岩浆作用和沉积作用如何导致古代VMS、VSMS和SEDEX矿床形成的认识。这项研究对加拿大经济（特别是北部经济）具有重要意义，并将改进这些重要金属资源的发现、勘探和开采的预测模型和方法。此外，它将为加拿大（和国际）矿产勘探和采矿部门的学术界，政府或工业部门培养高素质的人才。

Volcanic-hosted massive sulphide (VMS), volcanic- and sediment-hosted massive sulphide (VSMS), and sediment hosted massive sulphide (SEDEX) deposits are important sources of Canada's zinc, lead, copper, silver and gold.  These deposits are commonly associated with environments where tectonic plates are separating relative to one another called 'rifts'.  Rift environments are commonly associated with magmas, volcanoes, and the deposition of sedimentary rocks - most of which are formed underwater in ancient ocean and sedimentary basins.  In addition, heated metal-rich fluids called 'hydrothermal fluids' circulate through the rock packages within the rifts ultimately forming the VMS, VSMS, and SEDEX deposits.  This research grant is aimed at studying the interrelationships between magmatism, sedimentary rocks, and hydrothermal fluid history associated with these rifts within the rocks of the Cordilleran mountain system in the Yukon and northern British Columbia (+/-NWT).  The research is primarily aimed at understanding the temporal variation in the style of magmatism as well as the sedimentary rock depositional history within rift environments.  These studies will increase our understanding of how rift magmatism and sedimentation result in the formation of ancient VMS, VSMS, and SEDEX deposits.  This research has important implications for the Canadian economy (and in particular the northern economy) and will improve predictive models and methods for the discovery, exploration, and exploitation of these important metal resources.  Furthermore, it will train hihgly qualified persons for the careers in academia, government, or industry in the Canadian (and international) mineral exploration and mining sector.
