9618325 Zumberge This award will support a gravity study of sulphide deposits in the Middle Valley region off the northwest cost of the United States. These deposits occur where hydrothermal circulation systems discharge at the seafloor and provide a unique guide to the formation of similar deposits that are mined on land. Cores of these deposits have been recovered by the Ocean Drilling Program. The distribution of sulphides in the sediments in these area is reasonably well known at the core locations. The objective of the present project is to use this existing data to verify the capability of a new towed gravimeter system developed by the principal investigator, and to provide new information on the overall distribution of sulphides in the sediments surrounding the drillholes. ***

9618325 Zumberge 该奖项将支持对美国西北海岸附近的中谷地区硫化物矿床的重力研究。 这些矿床出现在热液循环系统在海底排放的地方，并为陆地上开采的类似矿床的形成提供了独特的指导。这些矿床的岩心已通过海洋钻探计划回收。 在这些区域的沉积物中硫化物的分布在岩心位置是众所周知的。本项目的目标是利用现有数据验证首席研究员开发的新型拖曳式重力计系统的能力，并提供有关钻孔周围沉积物中硫化物总体分布的新信息。 ***
