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

太古宙金矿床是加拿大最重要的黄金来源。虽然阿比提比省的金矿正在顺利开采，但邻近的瓦瓦省的勘探相对较少，但该地区也有类似的潜力，可以拥有世界级的金矿。可用于找矿钻探的区域金矿化模式缺乏，阻碍了洼洼副省的找矿工作。Wawa副省Michipicoten绿岩带是利用现有金矿开发区域金矿模型的天然实验室，该模型可应用于整个Wawa副省和世界范围内的造山带金矿。**这个多学科研究项目的主要目标是：(1)确定了海岛金矿的构造环境及其对金矿化的控制作用；(2)评价了与成矿相关的蚀变性质和程度，并对海岛金矿的含矿原岩进行了表征；(3)定量分析了从穿越瓦瓦片麻岩域的Michipicoten绿岩带（含岛金矿）到以东的Kapuskasing隆起的变质品位变化。该研究项目建立在先前在Michipicoten绿岩带的研究基础上，将产生一个增强的构造地层框架，以优先考虑在局部和区域尺度上的勘探，并测试造山带金矿的地壳连续体模型。* * * * * *

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. ******
