U.S.-China Cooperative Research (Geochem): Chemical and Isotopic Investigations of Mantle Xenoliths from Northeast China

该奖项支持了中国东北地区化学和地幔捕虏体的合作研究，并为美国科学家提供了一个重要的机会，研究和采样来自一个合作研究机会有限的地区的年轻火山岩。美国首席研究员、斯克里普斯海洋研究所的道格拉斯·麦克杜格尔将与中国科学院贵阳地球化学研究所的科学家合作，对中国岩石圈选定区域的演化进行表征和了解。样本将在中国收集，并主要在美国进行分析，中美两国科学家将在项目的两个阶段共同参与。预计这项研究将有助于了解地球上地幔的化学成分，并进一步发展中美科学家之间的合作关系。

This award supports cooperative research on chemical and mantle xenoliths from Northeast China, and provides an important opportunity for US scientists to study and sample young volcanic rocks from an area which has had only limited opportunities for collaborative research. The US principal investigator, Douglas Macdougall, of Scripps Institue of Oceanography, will work with scientists at the Chinese Academy of Science's Institute of Geochemistry in Guiyang, to characterize and understand the evolution of selected areas of the Chinese lithosphere. Samples will be collected in China, and analyzed primarily in the US, with joint participation by US and Chinese scientists in both phases of the projects. This research is expected to contribute both to understanding of the chemical composition of the earth's upper mantle and to the further development of cooperative relationships among US and Chinese scientists.
