Autochthonous construction of archean greenstone belts

该研究项目将研究加拿大地盾中25亿年的前寒武纪火山岩是如何随时间变化的，以及这种变化的原因。研究将试图证明，一些变化是由于周期性造山活动造成的，而另一些变化是由于海平面的上升和下降造成的。这项研究将考察加拿大地盾的阿比提比地区、安大略省西北部以及澳大利亚和格陵兰岛的前寒武纪地盾的古代火山岩。这项工作还将产生阿比提比绿岩带的第一个三维计算机生成模型，这是一个前寒武纪火山岩带，从蒂明斯和柯克兰湖一直延伸到魁北克的奇布加莫。3D模型将通过预测冰川沉积物和较年轻沉积岩覆盖下的单元范围，帮助铜矿和锌矿的勘探更加有效和高效。这个项目将是第一个证明绿岩带的主要单位，包括那些有铜锌矿床的单位，可以在远距离和第三维度上进行追踪和对比的研究。这项工作对勘探新矿藏的影响将是巨大的，因为它将增加发现新矿藏的成功率，从而支持北方经济。

The research Project will examine how the 2.5 billion year old Precambrian volcanic rocks in the Canadian Shield vary with time and the causes of that variation. The research will attempt to demonstrate that some of the variation is due to cyclical mountain-building events and some of the variation is due to the rise and fall of sea level. This research will examine ancient volcanic rocks in the Abitibi area of the Canadian Shield, in northwestern Ontario and in the Precambrian shield of Australia and Greenland. The work will also produce the first 3 dimensional computer-generated model of the Abitibi greenstone belt, a zone of Precambrian volcanic rocks extending from Timmins and Kirkland Lake through to Chibougamau in Quebec. The 3D model will help to make the exploration for copper and zince deposits more effective and efficient by predicting the extent of units beneath the cover of glacial deposits and younger sedimentary rocks. This project will be the first study to demonstrate that major units of Greenstone belts, including those with copper-zinc mineral deposits can be traced and correlated over large distances and in the third dimension. The impact of the work on exploration for new mineral deposits will be substantial in that it should increase the success in finding new deposits and thus supporting the northern economy.
