Lineament Analysis of Morphostructures of the Uchur-Maya Basin (Southeastern Siberian Platform) from SRTM Data: Relationship with Metallogeny

Abstract

Based on digital elevation models SRTM03 and SRTM30_Plus (Shuttle Radar Topography Mission Survey) the technique for detecting major structural elements and elucidating details of the geologic structure including discrimination of linear structures and texture features is elaborated. The computation of the modulus of the first derivative by the coordinate, i.e., the modulus of the topography gradient, characterizing the state of the surface by steepness and direction of slope (azimuth) is assumed as a basis. The technique was applied for the study of tectonics and metallogeny of the Uchur-Maya Meso-Neoproterozoic basin. The structural and lithological controlling factors of ore occurrences are established. It has been shown the efficacy of using the transformed digital elevation models for the geological and tectonic studies.

“…Hence, the Geoscientists have been concentrating more in mapping the folded structures and lineaments for mineral exploration. The Purulia, West Bengal base metal mineralization in proximity to Ranchi Mega lineament (Ashok Kumar et al, 1994), the Olympic Dam Cu-Au-U-Rare Earth Element deposits, Australia (Woodall, 1994) along the surface and geophysical lineaments, copper mineralization, Khetri district, India 320 km long NE-SW Kaliguman lineament (Knight et al, 2002) and the low grade uranium deposit again along the above Kaliguman lineament in the north Delhi fold belt in the states of Rajasthan and Haryana (Yadav et al, 2002) and the metallogeny in Uchur-Maya Basin, Southeastern Siberian Platform is control by the lineaments derived from SRTM (Shuttle Radar Topographic Mission) data (Gil'manova et al, 2012), etc. are certain significant studies in this direction.…”
