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.

南二叠纪盆地 (SPB) 中部的沉积作用始于 Rotliegend 时代的一个巨大的普拉亚系统，逐渐演变成萨布哈系统。罗特利根德时代晚期发生了多次海洋入侵，最终该盆地被泽希斯坦海淹没。人们对这些早期的侵入知之甚少，并且通常不会在现有盆地模型中予以考虑。该项目旨在分析旋回地层背景下的侵入，主要是沉积学、古生物学以及岩心和电缆测井中的伽马射线特征。这应该有助于更好地了解对 SPB 发展至关重要的时期内海平面波动、盆地沉降、岩浆作用、气候条件和沉积物供应的相互影响。
