Industrial metals such as zinc are fundamental to everyday life and have long been a significantcomponent of Canada's economy. With the increasingly urgent need to transition to a 'green' economy, and inresponse to heightened international geopolitical tensions, Canada and other countries have prepared 'criticalminerals' lists and have started to prioritise academic research that will facilitate the discovery of geopoliticallystable sources of critical minerals. Discovering new sources of 'green' metals in large quantities sufficient toenable the transition away from hydrocarbons will be challenging, because most of the readily discerned oredeposits at Earth's surface have already been identified; what is now required is a new perspective on how tolook for 'blind' deposits. Searching for new ore deposits is greatly facilitated by understanding why knowndeposits are where they are, and how and when they formed. The critical metal zinc, and many desirableassociated trace elements, forms ore deposits in sedimentary rocks. Studies of the nature of and controls onknown ore deposits in sedimentary-rock-hosted ore systems can help focus mineral exploration. This projectwill address the origin of Zn mineralisation in an undeveloped, poorly known Zn camp in NWT, Gayna River,whose unusual geological setting resembles that of Earth's highest-grade Zn deposit, Kipushi, in DemocraticRepublic of Congo. This work will contribute substantially to the understanding of how, when, and whycarbonate-hosted Zn systems develop, and to the conceptual foundations that will underlie mineral explorationin Zn districts during the transition into the green economy of the future.

锌等工业金属是日常生活的基础，长期以来一直是加拿大经济的重要组成部分。随着向“绿色”经济转型的需求日益迫切，以及国际地缘政治紧张局势的加剧，加拿大和其他国家已经编制了“关键矿物”清单，并开始优先考虑有助于发现地缘政治稳定的关键矿物来源的学术研究。发现新的大量“绿色”金属来源，使其能够从碳氢化合物中过渡出来，这将是一个挑战，因为地球表面大多数容易识别的矿床已经被确定;现在需要的是如何寻找“盲”矿床的新视角。通过了解已知矿床的成因、形成的方式和时间，可以极大地促进新矿床的寻找。锌是沉积岩中的重要金属元素，它与许多伴生微量元素一起形成矿床。研究沉积岩成矿系统中已知矿床的性质和控制因素，可以帮助确定矿产勘探的重点。该项目旨在探讨位于西北地区Gayna河一个未开发、鲜为人知的锌矿床中锌矿化的起源，其不寻常的地质背景类似于地球上最高品位的锌存款，位于刚果民主共和国的Kipushi。这项工作将大大有助于了解如何，何时，以及为什么碳酸盐托管锌系统的发展，以及概念基础，将在过渡到未来的绿色经济的锌地区矿产勘探。
