Fluvial geomorphology and neotectonic activity based on field and GPR data, Katrol hill range, Kachchh, Western India
چکیده انگلیسی
Based on the geomorphic and stratigraphic evidence, three major phases of Quaternary tectonic uplift in the Katrol hill range are inferred. The oldest pre-miliolite phase (middle Pleistocene) was followed by a prominent phase of fluvial incision with formation of gorges during early Holocene, and then by the last one during late Holocene, continuing at present. Uplift of the range occurred in well-marked phases during the Quaternary in response to differential uplift along the KHF under an overall compressive stress regime. GPR investigations at selected sites show that the KHF is a steep south-dipping reverse fault near the surface, which becomes vertical at depth. This suggests neotectonic reactivation of the KHF under a compressive stress regime, responsible for active southward tilting of the Katrol hill range.
