新疆和田地区北部幔源岩浆活动及地球化学特征

It is one of the leading subjects and frontiers in the up-to-data earth sciences about the continent mantle's property 、component、structure and dynamics .The research about the mantle of the Talimu platform ,especially it's south edge ---the north part of the Hetian area, directly influences the basic geologic research and prospecting of this area .By system research the mantle magma and the mantle-derived minerals which were obtained from the course of diamond prospecting by heavy mineral concentration ,this work deduces the mantle's geochemistry character 、the ancient mantle temperature 、oxygen fugacity and the location of the lithosphere and the asthenosphere etc, which will fill in the research blank of this area and will provide invaluable reference and reliable information for the basic geologic research and prospecting in the future.

大陆地幔的性质、成份、结构和动力学是当代地球科学的主题和前沿之一。塔里木地台、尤其是南缘之和田地区北部的地幔研究，直接影响该区基础地质及找矿工作。本项目拟通过对幔源岩浆及其中地幔物质以及金刚石重砂找矿中所获幔源矿物的系统研究反演地幔的三维地球化学特征、古地温、氧逸度、岩石圈、软流圈位置等。.
