The tectonics of south east Asia is a complex of active interactions between many oceanic, microcontinental blocks and mainland Asia including China with an overall convergent aspect. As such, the area represents a natural laboratory for study of terrane amalgamation and accretions at an early stage that may result in a collage of accreted terranes such as northwestern North America. The approach taken is this project is to establish, by paleomagnetic data primarily, the overall paleo- geographic development of this region in order to provide a framework for more focused tectonic studies. This renewal will continue towards this goal by Paleomagnetic work in parts of Malaysia and the Philippines. These results will be used to test competing models of the tectonics of Southeast Asia.

东南亚大地构造是一个多大洋、微大陆块体与包括中国在内的亚洲大陆相互作用的复合体，总体上呈会聚状。因此，该地区代表了一个天然的实验室，研究早期阶段的混合和增生，可能会导致拼贴增生的混合物，如北美西北部。本项目主要是通过古地磁资料来建立该区古地理的总体发展，为更有针对性的构造研究提供一个框架。通过在马来西亚和菲律宾部分地区的古地磁工作，这一更新将继续朝着这一目标前进。这些结果将用于测试东南亚构造的竞争模型。
