Abstract
The report highlights the problems of the identification of anomalies with the disjunctive dislocations and related zones of crustal heterogeneities into the outer components of the existing landscape (geoindicators) revealed by means of remote sensing data (RSD).
On the theoretical and literature sources grounds as well as using the example of the Central Transverse Segment of the Dnieper-Donets Depression (DDD) it has been shown that the disjunctive criteria played the key role in the following processes: sedimentation, folding, geo-fluid dynamics, formation of the reservoirs in the rocks (sometimes in basement rocks). The geotectonic development characteristics for the disjunctive dislocation over the stages of geological time, which are characterized by the most intensive sedimentation, are apparently responsible for the consistent patterns of spatial distribution of facies of proper deposits within their levels of terrace steps, as well as the occurrence of local structures and, thus, they are substantially stipulated the laws in the localization of prospecting oil-gas accumulation zones.
The results of study suggest that the great oil and gas prospecting interest is connected with the places of intersections (nodes) of the zone of multi-directional disjunctive dislocations mainly lateral and transverse ones relative to the spreading of region. The node localities of the multidirectional disjunctions can be considered as the prospecting hydrocarbon traps favorable for the oil exploration as a result of intensive development of geo-fluid dynamic processes in the crust, especially, at the newest stage of tectonic genesis taking account of their geo-indication manifestation. It is they, which are attracted for both the known oil and gas fields in the DDD and prospecting local structures distinguishing by geological-geophysical studies and which are potentially productive according to the thematic interpretation of RSD.
