KARPINSKY LINEAMENT – A STRUCTURAL ELEMENT OF ANCIENT REGHMATIC FAULT NETWORK OF EURASIA

Abstract

Based on the generalization of literary and cartographic materials, including the space survey data, the features of the spatial position, segmentation and tectonic position of the global trans-Euroasian dislocation belt and planetary fracturing, the Karpinsky lineament, were clarified. The described geomorphic structure is an integral part of the naturally spatially oriented ancient reghmatogenic fault framework of Eurasia, formed in the early stages of the rigid crust formation under the influence of cosmic rotational factors. The lineament at its various sites consists of various morphotectonic geostructural elements (linear grabens, shaft-like uplifts, folded depressions and orogens, suture zones, etc.). It dissects and divides the blocks of the earth's crust, which are very different in their nature and rank (ancient and young platforms, shields, zones of the Mezo-Cenozoic epiplatform orogeny, folded conflict zones), being a single transcontinental cross-cutting structure. The conjugation of these heterogeneous elements within one belt of concentration of deep faults is controlled by a long-lived quasi-stationary ordered planetary regmatic fault network, its north-west diagonal system. The Karpinsky lineament is divided in the longitudinal direction into two parts of the largest rank – the north-western paleorifthogenic (Pripyat graben – Tuarkyr folded zone) and the south-eastern collision shear (Central Mangyshlak – South Tien Shan), which differ in the structural pattern of faults and the prevail-ing dynamic mode of formation. The extent of the total longitudinal shear dislocations for the north-west paleorifthogenic part of the line-ament is within the first tens of kilometers, in most cases several kilometers; for the southeastern collision shear part, this order is larger, but does not exceed 2% of the total belt length, which makes it possible to characterize these dislocations as relatively low-shear.
