Transitions and Zoning in Porphyry-Epithermal Districts: Indicators, Discriminators, and Vectors

我们的目标是提高对斑岩-浅成热液矿区矿床成因和勘探成功的认识。这些地区可能有斑岩型铜钼金矿床(世界上主要的铜来源)、浅成热液型金银矿床、夕卡岩型和沉积型金矿。这些地区仍然是铜和金矿勘探者的重要目标，尽管很难识别大片背景蚀变带内的矿带。我们将制定和测试可供勘探者用来指示远景环境、区分成矿类型和指向矿带的标准--无论是斑岩、浅成热液和/或其他外围类型。

We aim to improve understanding of ore genesis and exploration success in porphyry-epithermal mineral districts. These districts can contain porphyry Cu-Mo-Au deposits (the world's major source of copper), epithermal Au-Ag deposits, skarn and sediment-hosted gold deposits. These districts continue to be important targets for copper and gold explorers, even though it can be difficult to identify the ore zones within large zones of background alteration. We will develop and test criteria that can be used by explorers to indicate prospective environments, discriminate between mineralization styles, and vector towards ore zones - be they of porphyry, epithermal, and/or other peripheral styles.
