Geodynamic origins and tectonic accretion of late Archean terranes

这笔资金将用于调查导致大陆形成的板块构造过程，这些过程发生在大约2.7亿年前的太古代晚期。重点将放在安大略省和魁北克省南部的苏必利尔省。该地区保存了非常大而完整的太古宙构造岩石记录。它也是加拿大最重要的矿产资源储藏库之一。这项研究将包括广泛的地质实地工作和地图绘制。野外工作将通过切割年龄矿物测年技术和计算岩石形成时的压力(深度)和温度来补充。对构造过程和构造结构的实验研究也将补充实地研究。实验将有两种类型，数值和模拟(由物理材料组成的比例模型)。这笔研究助学金将同时支持三名博士生。

The funding will be used to investigate the plate tectonic processes that were responsible for the formation of continents, in Late Archean time, ca. 2700 million years ago. The focus will be on the southern Superior tectonic province, in Ontario and Quebec. That region preserves a very large and complete rock record of Archean tectonics. It is also one of the most important reservoirs of mineral resources in Canada. The study will include extensive geological field work and map-making. The field work will be complemented by cutting age mineral-dating techniques and by calculations of the pressures (depths) and temperatures at which the rocks formed. Experimental studies of tectonic processes and tectonic structures will also complement the field-based studies. The experiments will be of two types, numerical and analog (scaled models composed of physical materials). The research grant will support three concurrent PhD students.
