EFFECT OF OIL POTENTIAL AND DEEP TECTONICS ON THE TRACE ELEMENT COMPOSITION OF SOILS: AN EXAMPLE OF THE TATARSTAN REPUBLIC

Abstract

Published seismic data were considered in combination with the results of lithogeochemical and electrochemical data on soils above oil reservoirs and subvertical dynamic anomalies at the territory of Tatarstan. The effect of oil potential and deep-seated tectonics on the trace element composition of soils was exemplified along several seismic profiles across the Southern Tatar and Northern Tatar arches. Elevated contents of Li, B, Al, and As were recorded above dynamic anomalies, while oil accumulations are marked by high contents of V, Ni, Cu, Mo, and Ag.
