Identification of intrusive objects from seismic data within the Ledovoe field in the Barents Sea
https://doi.org/10.18303/2619-1563-2023-1-38
Abstract
The seismic field of the Triassic deposits of the sedimentary section of the Barents Sea is characterized by numerous reflections of increased intensity. These reflections are due to the Jurassic-Cretaceous basaltoid magmatism. On the case of the Ledovoe field, the features of the waves propagation associated with the intrusions – multi-tiered sills are shown. Regularities in the distribution of increased seismic time thicknesses of the mapped sills are revealed, and their relation to faults is established.
