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

9614460克莱恩今天美国矿产勘探的主要焦点是寻找卡林型金矿(CTGD)。这些是位于内华达州北部的大型、低品位、以沉积物为宿主的系统，以存在微米级的“看不见”的黄金而闻名。尽管它们具有重要的经济意义，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。这项提议的主要目标是提供方法，以确定对卡林型金矿化的形成至关重要的地质过程。具体地说，这项研究的目的是确定CTGD上参与金属运输和沉淀的流体是否与变质作用或岩浆作用有关。此外，这些结果将为勘探战略提供新的方向，并可能产生可用于随后在大盆地和世界其他地区勘探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.
