Abstract

The Sea of Galilee (Lake Kinneret) is located in northern Israel in a complex tectonic setting where the Dead Sea Transform crosscuts other fault systems. The practical absence of boreholes in the sea hinders geological-geophysical data interpretation. For the first time, gravity, magnetic, paleomagnetic, radiometric, and seismological data were analyzed together. An integrated analysis of gravity and seismological data made it possible to clarify some tectonic parameters. The total magnetic field map shows an intricate pattern caused by a combined influence of the basalt flows of various ages and magnetization in and around the sea. Calculated statistical-probabilistic parameters of the magnetic field indicate some essential peculiarities of the medium. The recognized magnetic anomalies were analyzed using methods of quantitative interpretation especially developed for the complex physical-geological environments. 3D magnetic field modeling allowed to reveal the following important features: thick basaltic plate occurrence in the southernmost sea basin, presence of the reversely magnetized basalts near the sea’s eastern boundary, and possible subsidence of basaltic bodies in the center of the pull-apart basin. The paleomagnetic stratigraphy of basalt associations around the Sea of Galilee basin proved to be correlated with the paleomagnetic zones and anomalies in the sea. The paleomagnetic characteristics of traps are linked with the development of the Dead Sea Transform. The previously constructed magnetic-paleomagnetic scheme with predominantly K–Ar dating has been significantly elaborated on the basis of newly arriving data. It is stated that a characteristic feature of the study area is the turns of tectonic blocks, mainly counterclockwise. The revised structural map of the Cover Basalts is intended to coordinate various geological and environmental investigations in this area.
