Structural and geophysical characterization of the Messinian evaporites and their tectonic evolution in the Levant Basin

该项目旨在深入了解地中海东部大量墨西尼亚蒸发岩的结构和动力学。由于其众所周知的几何形状，孤立的黎凡特盆地可以被视为一个天然实验室，在这里可以分别研究蒸发岩的沉积和初始构造以及潜在油气藏的早期发育。前人的研究表明，该盆地具有复杂的蒸发岩地层和沉积前后的变形。此外，有迹象表明耦合流体流过或流出蒸发演替，这显然与不渗透盐的既定假设相矛盾。过去，由于科学界无法获得适当的地球物理数据，因此无法对观测到的特征进行深入分析。最近，德国汉堡大学获得了高质量的工业多道地震数据（偏移量7.35 km， 144倍，9.1s TWT）。利用这些数据，我们将利用地震属性参数化各个蒸发层序和流体相关特征，从而揭示蒸发岩的演化历史以及流体流动和剧烈物质消耗等相关过程。通过该项目以及与持有同一地区3D地震数据的国际合作伙伴一起，将为未来的IODP提案确定可能的钻探地点。

This project aims on the advanced understanding of the structure and dynamics of the massive Messinian evaporites in the eastern Mediterranean. Owing to its well known geometry the solitary Levant Basin can be considered as a natural laboratory, where the deposition and initial tectonics of evaporites and the early development of potential hydrocarbon reservoirs, respectively, can be investigated. Previous studies pointed towards a complex evaporite stratigraphy and both syn- and post-depositional deformation. Furthermore, there are hints for coupled fluid flow through or out of the evaporitic succession, which apparently contradicts the established assumption of impermeable salts. In the past, any advanced analysis of the observed features has been prevented since no appropriate geophysical data were accessible to the scientific community. Recently, industrial multi-channel seismic data of outstanding quality (7.35 km offset, 144 fold, 9.1s TWT) have been released to the University of Hamburg. With this data we intend to parameterize the individual evaporitic sequences and fluid related features by means of seismic attributes and, consequently, unravel the evolutional history of the evaporites and related processes like fluid flow and intense mass wasting. From this project and together with international partners who hold 3D- seismic data from the same area, possible drill sites will be determined for a future IODP proposal.
