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.

新元古代萨格罗群的海洋沉积物（和相关的火山岩）广泛分布在摩洛哥阿特拉斯和反阿特拉斯。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。申请人计划与摩洛哥合作伙伴（埃拉奇迪亚Mulay Ismail大学的Brahim Karaoui博士）合作，利用LA ICPMS（德累斯顿Senckenberg自然历史收藏馆和法兰克福歌德大学）对20个样品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）。这些数据将有助于更好地了解冈瓦纳西北缘新元古代大地构造演化。
