Magnetic Model along the PANCAKE Geotransect in Relation to Hydrocarbon and Metallic Mineral Deposits and Occurrences

Summary A geomagnetic field analysis was performed and a magnetic model for the PANCAKE geotransect was developed in relation to hydrocarbon and metallic mineral deposits and occurrences. The Earth’s crust of the East European Craton and the transition zone to the structures of Central Europe has increased magnetization. The magnetic part of the Earth’s crust at depths of 15–20÷40–45 km is traced to the Pre-Carpathian fault. Gas fields are located above the deep blocks of the middle and lower parts of the Earth’s crust and oil fields are located in non-magnetic parts of the Earth’s crust. In the local geomagnetic field, the most regular relationship is observed for oil and oil condensate deposits, which are completely located within the boundaries of positive magnetic anomalies. Gas fields are more inclined to negative anomalies, or to gradient local zones. In the area Berehove uplift, andesite porphyrite shafts and andesite domes of Sarmatian age that are associated with gold, gold-polymetallic, and silver mineralization are marked by positive anomalies. Stibium mineralization zone is associated with the Pannonian-Pontic volcanic structures along the southern foot of the Vygorlat-Hutyn belt, and deposits and occurrences of bismuth and mercury are closely associated with intrusive formations of the Dacian-Romanian age.
