Geophysical assessments of the Valentine Lake gold deposit property, Central Newfoundland

将在纽芬兰西部对瓦伦丁湖进行严格的地面地球物理勘测，那里有两个重要的金矿和至少三个额外的探矿。该课程的主要目标是：利用探地雷达绘制地表覆盖图，以计算储水量，帮助钻探和未来矿场的上层建筑布置，并绘制隐藏断层图；利用探地雷达结果，利用地表重力测量来圈定金矿的赋存区域。其他计划的活动包括沼泽和湖泊沉积物岩心采样，以及磁势和自然电位(SP)测量。除了允许对探地雷达数据进行深度校准外，采样还将提供有关纽芬兰沉积物碳和水收支的信息，并可能表明过去的侵蚀模式。磁力测量与探地雷达结果相结合，将有助于圈定勘探区域附近的地下构造。SP测量是在矿床上测量表面电压，是探索性的：尚不清楚它们是否会提供与矿化、结构或表面材料相关的数据。所有的测量仪器都是纪念大学最先进的地球物理设备池的一部分。这项研究将为财产所有者和更广泛的资源勘探界提供宝贵的信息，说明地面地球物理对纽芬兰全岛一带的一种矿床类型的效用。尽管没有一项地球物理调查可以直接发现金矿，但这些调查将有助于找到最佳的钻探区域，并在对环境影响最小的情况下规划矿山。受雇于该项目的学生将接受一些高精度地球物理方法和数据分析方面的培训，培训环境将为他们成为高素质人员做好准备。

Rigorous ground geophysical surveys are to be carried out in western Newfoundland over the Valentine Lake Property, which contains two significant gold deposits and at least three additional prospects. The main aims, carried out by an MSc candidate and undergraduate students, are: to map surficial cover with ground penetrating radar (GPR) in order to calculate water reserves, help with drill and superstructure placement for the future mine and map hidden faults; and utilizing the GPR results, to use surface gravity measurements to delineate the region hosting the gold.Other planned activities include bog and lake sediment core sampling, and magnetic and self-potential (SP) surveys. The sampling, in addition to allowing depth calibration for the GPR data, will provide information on carbon and water budgets of Newfoundland sediments, and may indicate past erosion patterns. Magnetic surveys, in combination with GPR results, will to help delineate subsurface structures near the prospects. The SP surveys, where the surface voltage is measured over the deposit, are exploratory: it is not known they will provide data relevant to the mineralization, or to structure, or to surficial materials. All the survey instruments are part of the state-of-the-art geophysical equipment pool at Memorial University.This research will provide valuable information both to the property owners and the wider resource exploration community on the utility of ground geophysics over a deposit type that occurs in belts across the island of Newfoundland. Though no geophysical surveys can directly detect gold, the surveys will help in finding the best regions to drill and for planning the mine with minimal environmental impact. Students employed in the project will be trained in a number of high precision geophysical methods and data analysis in an environment that will prepare them for employment as highly qualified personnel.
