Timing of Precambrian Metamorphism and Magmatism in Madagascar: Implications for the Configuration and Fusion of Continental Fragments within the Gondwanan Supercontinent

小行星9418538 尽管冈瓦纳大陆的中、新生代裂解过程已被人们所熟知，但该超大陆的晚前寒武纪组装过程还不十分发育。 该项目涉及对马达加斯加结晶基岩的广泛年龄测定，这将有助于限制冈瓦纳内明显的古陆块体的配置和年龄以及东西冈瓦纳之间的融合时间。 这项工作将与南非几所大学正在进行的一个项目一起进行。 结果应该影响莫桑比克造山带的这一部分的时间演化，并提高对冈瓦纳超大陆的更大框架内的马达加斯加的地质环境的理解。

9418538 Tucker Although the Mesozoic and Cenozoic breakup of Gondwana is well understood, the late precambrian assembly of the supercontinent is not well developed. This project involves extensive age determination on the crystalline bedrock of Madagascar which will help constrain the configuration and age of the apparent cratonic blocks within gondwana and the timing of fusion between east and west gondwana. The work will be done in conjunction with an ongoing project within several South African Universities. Results should impact the temporal evolution of this part of the Mozambique orogenic belt and improve the understanding of Madagascar's geologic setting within the larger framework of the gondwana supercontinent.
