Stratigraphic markers in Archean Greenstones

研究集中在阿比提比绿岩带，这是一个古老的火山岩区域，横跨安大略省和魁北克省的边界，从蒂明斯到奇布加莫。这片火山岩带是金、铜和锌的来源，是该地区的经济命脉。研究表明，许多火山单元被富含铁的沉积物隔开，这些沉积物代表了火山活动的停顿。富铁沉积物中所含的矿物质和化学成分各不相同。这些岩石的化学成分随着它们离铜和锌矿化的远近而变化。这项研究将集中在如何利用化学变化来确定可能有新矿藏的地区。第二个项目将建立这个火山岩带的三维模型。该模型将使用基于计算机的技术建立，从而提高预测未来地雷位置的能力。该项目的第三个方面将是了解对火山活动和沉积岩生产随时间变化的控制。该项目的这一方面将检查加拿大和其他地方的绿岩带，以确定哪些类型的火山岩和沉积岩发生在哪里。

The research concentrates on the Abitibi greenstone belt, a region of old volcanic rocks that span the Ontario Quebec border from Timmins to Chibugamau. This belt of volcanic rocks is the source of the gold, copper and zinc that is the economic lifeblood of the region. Research as established that the many volcanic units are separated by iron rich sediments that represent pauses in volcanism. The iron-rich sediments vary in their contained minerals and their chemistry. The chemistry of these rocks vary as a function of how close they are to copper and zinc mineralization. The research will focus on how to use the variations in chemistry to identify likely areas with new mineral deposits. A second project will build a 3-D model of this belt of volcanic rocks. The model willbe built using computer based techniques and will result in improved ability to predict where future mines lie. A third aspect to the project will be to understand the controls on the variations in volcanism and production of sedimentary rocks with time. This aspect of the project will examine greenstone belts in Canada and elsewhere to establish the controls on what types of volcanic and sedimentary rocks occur where.
