The Evolution of a Playa to a Sabkha System (Permian, North German Basin)

南二叠纪盆地中部(SPB)的沉积作用始于旋转末期的一个巨大的Playa系统，逐渐演化为一个Sabkha系统。在旋转末期发生了多次海洋入侵，最后，泽克斯坦海淹没了盆地。人们对这些早期的入侵知之甚少，在现有的盆地模型中通常没有考虑到这些影响。该项目旨在分析旋回地层学背景下的海侵，主要是它们的沉积学、古生物学以及它们在岩心和电缆测井中的伽马射线特征。这将有助于更好地理解海平面波动、盆地下沉、岩浆作用、气候条件和沉积物供应之间的相互作用，而这一时期对太平洋生物多样性公约的发展至关重要。

Sedimentation in the central part of the South Permian Basin (SPB) started in Rotliegend times in a huge playa system which gradually evolved into a sabkha system. Numerous marine ingressions occured in late Rotliegend times before, finally, the basin became flooded by the Zechstein sea. Those early ingressions are little understood and normally not taken into account in the existing basin models. This project aims to analyse the ingressions in a cyclostratigraphic context, mainly their sedimentology, paleontology, and their gamma ray signature in cores and wireline logs. This should lead to a better understanding of the interply of sea-level fluctuations, basin subsidence, magmatism, climatic conditions and sediment supply in a period that was crucial for the development of the SPB.
