Abstract

The quantitative analysis of magnetic anomalies has been performed using advanced methodologies allowing the application of interpretation procedures under conditions of (1) oblique magnetization, (2) rugged terrain relief, and (3) superposition of anomalies of different ranks. Examples of unconventional magnetic anomaly analysis are presented for several geologically complex areas in northern Israel: the Sea of Galilee, Carmel, and Malqishon. The methodology of paleomagnetic mapping of such transition zones is based on the integration of the mapping techniques for both continental and oceanic platforms: paleomagnetic reconstructions, results of radiometric dating of magnetically active rocks, satellite data examination, tectonic-structural reconstructions, biogeographical studies, and utilization of the results of various geophysical surveys. In northern Israel, for the combined paleomagnetic mapping, were selected: (1) the Sea of Galilee with the adjoining zones (preliminary constructed schemes for these areas were revised and supplemented), (2) the Carmel area, and (3) Atlit area (internal part of the Carmel area). The paleomagnetic profile for the Carmel area on the top of the Lower Cretaceous traps accumulative surface indicates the complex history of the region's paleogeodynamic evolution. This testifies to the effectiveness of combining magnetic anomaly quantitative interpretation with the paleomagnetic mapping of complex media. The constructed palinspastic reconstruction map (for the period of 3.6-2.0 Ma) unmasks important tectonic-magmatic features of that geological time.
