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.

Neopereroxoic Saghro群体的海洋沉积物（以及相关的火山）在摩洛哥地图集和反atlas中广泛。但是，对于摩洛哥东部的露头，关于年龄限制，地理环境和沉积物出处的数据很少。 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).这些数据将更好地理解冈瓦纳西北边缘的新元古代地理演化。
