Comparison of 3D integrated geophysical modeling in the South Caucasian and Eastern Mediterranean segments of the Alpine-Himalayan tectonic belt

South Caucasus (including Azerbaijan) and Easternmost Mediterranean (including Israel) are located within the Alpine-Himalayan tectonic belt and are characterized by complex and variable tectono-geological patternы. To study еру deep structure of these areas several regional interpreting profiles indicating results of 3D combined gravity-magnetic modeling were selected. Development of the initial physical-geological models (PGMs) is realized by utilization of the known surface geology, drilling data examination, previous seismic, magnetotelluric and thermal data analysis, careful investigation of the petrophysical (including paleomagnetic) data, as well as qualitative and quantitative analysis of gravity-magnetic materials. After thatб an iterative 3D modeling accompanied by changing geometrical boundaries of geological bodies (and assuming new targets) and varying physical properties (density, magnetization, and magnetic vector inclination) is started. This process has been completed by the development of final PGMs. Creating the final PGMs means not only determining the minimal difference between the observed and computed gravity and magnetic fields, but also compliance of the models satisfying the known geological principles (complex geological PGMs of the regions under study often compose intricate structural-tectonic puzzles). The final PGMs reflect the key structural-tectonic specifics of the regional geological structure, beginning from the subsurface (hundreds of meters) up to the Moho discontinuity (tens of kilometers). The PGMs revealed primarily the boundaries of tectonic blocks, masked faults, buried uplifts of the basement, occurrence and form of various magmatic bodies, and most important factors controlling ore- and hydrocarbon-bearing formations, and some other features. This investigation briefly summarizes the principles and possibilities of the advanced 3D combined modeling of gravity and magnetic fields and presents several essential PGMs for the regions under study.
