Paleomagnetic Studies on the Tectonic Evolution of China

本项目对中国北部和西北部5个地点的石炭纪-侏罗纪岩石进行了古地磁研究。研究结果将有助于解决中国大地构造演化中的三大问题，即华北大地构造在这一时期的形态、华北地块与华南地块的融合以及中国向西伯利亚的吸积。在与兰州地质研究所的中国地质学家协商后，根据所需岩石的年龄、暴露程度、岩性对古地磁研究的适用性以及构造和年龄控制的良好程度，选择了重点地区的采样地点。

This project is a paleomagnetic study of rocks of Carboniferous-Jurassic age from five locations in northern and northwestern China. The results should contribute significantly to the solution of three major problems in the tectonic evolution of China: namely, the configuration of terranes of northern China during this time, the amalgamation of the North and South China Blocks, and the accretion of China to Siberia. The sampling locations in key areas were selected in consultation with Chinese geologists at the Lanzhou Institute of Geology according to the ages of rocks desired, excellence of exposure, suitability of lithologies for paleomagnetic study, and goodness of structural and age control.
