RUI: Carlin-Type Gold Deposits - Products of Magmatism or Metamorphism?

9614460克莱恩当今美国矿产勘探的主要重点是寻找卡林型金矿（CTGD）。这些是位于内华达州北方的大型低品位沉积物系统，以存在微米级“看不见的”金而闻名。 尽管它们在经济上很重要，但导致这些矿床形成的地质过程仍然不清楚，地质模型仍然是描述性的。 该提案的主要目标是提供识别卡林型金矿化生成所必需的地质过程的方法。 具体来说，这项研究的目的是确定流体参与的运输和沉淀的金属CTGD的遗传联系到变质或岩浆过程。此外，这些结果将为勘探战略提供新的方向，并可能产生可用于以后在大盆地和世界其他地区探索CTGD的遗传模型。

9614460 Cline The major focus of mineral exploration in the United States today is centered on the search for Carlin-type gold deposits (CTGD). These are large, low-grade, sediment-hosted sytems located in northern Nevada, which are noted for the presence of micron-sized "invisible" gold. In spite of their economic importance, the geological processes that caused the formation of these deposits remains obscure and geological models continue to be descriptive. The main goal of this proposal is to provide ways to identify the geological processes that were essential to the generation of Carlin-type gold mineralization. Specifically, this study will aim to define if fluids involved in the transport and precipitation of metals on CTGD's are genetically linked to metamorphic or magmatic processes. Furthermore, these results will provide new directions for exploration strategies and could produce genetic models that can be used later to explore for CTGD in the Great Basin and other parts of the world.
