Abstract
This paper discusses the possibilities of structural interpretation of space images and morphometric analysis of the latest tectonic movements, which are still poorly studied in the oil-and-gas bearing area of the junction of the Ustyurt (Takhtakairsky ridge) and the north-western part of the Bukhara-Khiva region (Khorezm monocline and Mishklinsk uplifting, Dashkalinsk and Birgutli-Shortaklinsk troughs). As a result, lineament and “strip” geodynamic zones of abnormal fracturing were identified. Their formation is probably associated with the accumulation of diagonal stresses of the gradient zones of structural-tectonic framework, within which fault-block structures are distinguished. Morphometric analysis showed that under the influence of modern tectonics, local positive structures with predominantly gas-filled traps correspond to areas of maximum activation.
