9316479 Opdyke Considerable progress has been made in understanding the various collisions between major blocks of China, however uncertainty still exists about the timing of collisions between the North China Block, the South China Block and the Indochina Block during the Mesozoic due to remagnetization. This work will study Middle Triassic rocks from three localities where preliminary paleomagnetic data suggest a promise of primary magnetization. Results will shed light on the Mesozoic remagnetization place constraints on the timing of block collision and help to fit China into the global Mesozoic plate loop.

小行星9316479 尽管对中国主要地块之间各种碰撞的认识已取得了相当大的进展，但由于再磁化作用，华北地块、华南地块和印支地块在中生代碰撞的时间仍然存在不确定性。 这项工作将研究三个地方的中三叠世岩石，初步的古地磁数据表明，初级磁化的承诺。 研究结果将有助于阐明中生代板块再磁化对块体碰撞时间的制约，并有助于将中国纳入全球中生代板块环。
