9508013 Hanson This project will conduct mapping and geochronological studies of the Zambezi orogenic belt in southern Africa. Although this belt is highly significant to Neoproterozoic to early Paleozoic plate reconstructions, it is geologically very poorly understood. The study will collect U/Pb, 40Ar/39Ar and Sm-Nd isotope data from critical samples in Zimbabwe during detailed mapping traverses. The results will constitute the first data set of its kind from the Zambezi belt and will allow its tectonic history to be determined for this first time. The data will also be significant for Neoproterozoic plate reconstructions and understanding the assembly of the central part of the Gondwana supercontinent.

9508013 Hanson该项目将对南部非洲的Zambezi造山带进行映射和年代学研究。 尽管该皮带对新元古代至早期的古生代板重建非常重要，但在地质学上，它的理解很差。 该研究将在详细的映射遍历期间从津巴布韦关键样本中收集U/PB，40AR/39AR和SM-ND同位素数据。 结果将构成Zambezi Belt的第一个同类数据集，并将首次确定其构造历史记录。 数据对于新元古代板的重建也很重要，并了解冈瓦纳超大陆中央部分的组装。
