Age, trace element and isotope composition of detrital zircon in Saghro Group sediments (Neoproterozoic, Morocco): The missing link in the geotectonic evolution of the northwestern edge of Gondwana

新元古代萨格罗群的海洋沉积物(和伴生火山岩)广泛分布在摩洛哥地图集和反地图集中。然而，对于摩洛哥东部的露头，关于年龄限制、大地构造环境和沉积物来源的数据很少。申请者计划与摩洛哥合作伙伴(穆莱·伊斯梅尔大学埃拉赫迪亚的Brahim Karaoui博士)合作，利用LA ICPMS(德累斯顿森肯堡自然历史收藏和法兰克福歌德大学)对20个样品中的碎屑锆石进行测量，以确定年龄、微量元素和同位素组成(Lu/Hf)。这些资料将对冈瓦那西北缘新元古代大地构造演化提供更好的认识。

The marine sediments (and associated volcanics) of the Neoproterozoic Saghro Group are wide-spread in the Moroccan Atlas and Anti-Atlas. However, for the outcrops in eastern Morocco, data on age constraints, geotectonic environment and sediment provenance are scarce. In cooperation with a Moroccan partner (Dr. Brahim Karaoui, Mulay Ismail University, Errachidia), the applicants plan to carry out measurements on detrital zircon from 20 samples to determine age, trace element and isotope composition (Lu/Hf) with LA ICPMS (Senckenberg Collections of Natural History, Dresden, and Goethe University, Frankurt). These data will provide a better understanding of the Neoproterozoic geotectonic evolution at the northwestern edge of Gondwana.
