岩浆硫化物矿床是一种特殊的存款，与大量的喷流有关 被称为大火成岩省或LIPs的火山岩。这些省可以是数百万立方 可作为镍、钴、钛、钒、铜的重要来源， 铂族元素的开采每年为加拿大带来数十亿美元的收入。 经济然而，由于这些矿床中最容易进入的已经被发现， 有限的生命周期，新的发现是必不可少的加拿大的资源部门，并将在更多的发现 或者隐藏在地下深处。此外，构成LIPs（火山岩）的岩石 和它们更深的等价物）并不是都能够容纳矿石， 尽管它们有共同的来源。该项目旨在探索 对于这些矿床，通过高精度的铀同位素测量， 和铅在LIP岩石中发现的特定矿物中。这将使他们的年龄计算到高精度， 这样，可以识别和评估火成岩活动的不同阶段的前景， 从事漫长而昂贵的钻探活动，以收集和测试可能数百万美元的石油， 毫无价值的样品我们的行业合作伙伴将确定适当的样本套件以进行日期确定 将进行最先进的放射性同位素分析，从而将工业界聚集在一起， 拥有丰富的矿产资源经验和世界一流的学术研究人员。

Magmatic sulphide deposits are a specific kind of ore deposit that is associated with voluminous outpourings of volcanic rocks known as Large Igneous Provinces, or LIPs. These Provinces can be millions of cubic kilometres in volume, and can be significant sources of nickel, cobalt, titanium, vanadium, copper, and platinum group elements - the mining of which contributes billions of dollars annually to the Canadian economy. However, as the most accessible of these ore deposits have already been discovered and mines have limited lifetimes, new discoveries are essential for Canada's resource sector and are to be found in more challenging locations or hidden deeper underground. Furthermore, the rocks that make up LIPs (volcanic rocks and their deeper equivalents) are not all capable of hosting ore, and there can be a great deal of variability within a single LIP's rocks despite their having a common source. This project aims to make the exploration for these ore deposits easier and more accurate though high-precision measurements of the isotopes of uranium and lead in specific minerals found in LIP rocks. This will enable their ages to be calculated to high precision, such that distinct phases of igneous activity can be identified and assessed as to their prospectivity without engaging in lengthy and expensive drilling campaigns to collect and test what could be millions of dollars' worth of worthless samples. Our industry partners will identify appropriate suites of samples for dating analysis, and state-of-the-art radio-isotopic analyses will be carried out, thereby bringing together industry experience with mineral resources and world-class academic researchers.
