Structural and Tectonic Zoning of Paleozoic Deposits of Western Taimyr
https://doi.org/10.18599/grs.2024.3.8
Abstract
Based on an actual seismic geological model, a structural-tectonic zoning of the Paleozoic complex of Western Taimyr was carried out, including the territory of the South Taimyr monocline, where Paleozoic deposits are hidden under the Mesozoic sedimentary cover. Zoning was carried out for tectonic elements of different orders: regional, supra-order, structures of the 1st, 2nd, 3rd orders, local uplifts. When compiling a structural-tectonic scheme, an analysis of previous tectonic schemes by various authors and currently available materials was performed. In addition, much attention is paid to the main faults of Western Taimyr.
All available geological and geophysical data reflecting the tectonic structure of the study area was used, including structural maps of the top of the Paleozoic complex and horizons reflecting it’s internal structure, 2D CDP seismic sections, maps of potential fields (magnetic and gravity), maps of dips and azimuths of reflecting horizons, thickness maps, published and archive papers on this topic, including tectonic and geological maps.
As a result, an updated structural-tectonic diagram of the Paleozoic deposits of Western Taimyr was compiled, characterized by a high degree of detail, the fault model of the region was generalized and significantly refined, all tectonic elements and structures were assigned their own names, taking into account the results of previous studies, positive structures of the 1st order, which represent potential zones of oil and gas accumulation in the Paleozoic complex.
