Abstract

This study focuses on some major aspects of the structure and evolution of Lake Kinneret. The complicated, and still not completely understood, structure and complex tectonic history of the region are the main questions addressed in this work. We also consider the existence of transverse faults at the termination of the basin, the continuity of slip through time, and the occurrence of salt bodies under the lake. The study is based mainly on the results of a reprocessed and reinterpreted multichannel reflection seismic survey of Lake Kinneret. The processing resulted in enhanced images that demonstrated more details and improved the interpretability of the data. Mapped seismic reflectors reflect the complex structure and evolution of the basin. Modification and refinement of the schematic structure model of the lake is proposed. Boundary faults with a large vertical throw delimit the basin in the east and southwest, while transverse fault zones divide the basin into several segments. A deep sub-basin is located in the southern part of the lake and delimited by a southern transverse fault and a zone of distortion in the central part of the lake. It seems that activity along these faults began around 2.0-1.7 Ma and is connected to possible changes in the geometry of the transform. A complex zone of deformations delimits the northern sub-basin to the west. The western marginal fault may be at least a part of these deformations. Tectonic activity along this fault appears to have migrated northward over time.
