Tectonic, geochemical and metamorphic controls on gold mineralization at the island gold deposit and surrounding region, Michipicoten Greenstone Belt, Ontario

太古宙金矿是加拿大最重要的黄金来源。虽然Abitibi次省的金矿开采正在顺利进行，但邻近的Wawa次省相对勘探不足，但该地区拥有类似的世界级金矿储量潜力。可用于定向勘探钻探的区域金矿化模型的缺乏阻碍了瓦洼省的勘探。瓦瓦省的Michipicoten绿岩带代表着一个天然实验室，可以利用现有的金矿来开发区域金矿模式，这些模式可以应用于该省和世界各地的造山型金矿。这一多学科研究计划的主要目标是：(1)确定岛金矿床的构造背景和对金矿化的控制；(2)评估与矿化有关的蚀变性质和程度，以及表征岛金矿矿化的原岩；(3)量化从Michipicoten绿岩带(岛金矿所在的)到卡普斯卡金向东隆起的Wawa片麻岩区域的变质程度变化。这项研究计划建立在Michipicoten绿岩带以前的研究基础上，并将产生一个增强的构造地层框架，以优先在当地和区域范围内进行勘探，并测试造山型金矿床的地壳连续体模型。

Archean gold deposits are the most important source of gold in Canada. While mining of gold deposits in the Abitibi subprovince is well underway, the neighbouring Wawa subprovince is relatively underexplored, but this region has a similar potential for hosting world-class gold deposits. The paucity of regional gold mineralization models that can be used to target exploration drilling has hindered exploration in the Wawa subprovince. The Michipicoten greenstone belt in the Wawa subprovince represents a natural laboratory to use existing gold deposits to develop regional models of gold deposits that can be applied across this subprovince and to orogenic gold deposits worldwide. The main objectives of this multidisciplinary research program are to: (1) determine the structural setting and control on gold mineralization at the Island Gold deposit, (2) evaluate the nature and extent of alteration associated with mineralization as well as characterize the protoliths that host mineralization at the Island Gold mine, and (3) quantify the change in metamorphic grade from the Michipicoten Greenstone belt (hosting the Island Gold Mine) across the Wawa gneiss domain to the Kapuskasing uplift to the East. This research program builds on previous studies in the Michipicoten Greenstone belt and will generate an enhanced tectonostratigraphic framework to prioritize exploration at the local and regional scales and test the crustal continuum model for orogenic gold deposits.
