This study is an attempt to reconstruct the history of sedimentation and landform evolution in the western Great Rann of Kachchh. Field stratigraphy, sedimentology, geochemistry, optical and radiocarbon dating suggest dominance of tidal flat sedimentation with subordinate contribution coming from the southern-draining streams during 5.5 to 2 ka. Variability in the geochemical proxies are interpreted as a surrogate for tidal energy (viz. Zr and Cr) which, along with the major elemental ratios (TiO2/Al2O3and K2O/ Al2O3), indicate enhanced tidal energy condition during 5.5 to 5 ka and around 3 ka. A close correspondence of the major and trace elements with those of the Indus River sediment and the dominance of illite suggest the Indus River was a major contributor for western Rann sedimentation during the mid-Holocene. These sediments were routed through the Kori Creek during marginally high sea level until around 2.2 ka and the present landscape was largely sculptured after the 1819 Allah Bund earthquake.

Ice-rich permafrost landscapes are sensitive to climate and environmental change due to the melt-out of ground ice during thermokarst development. Thermokarst processes in the northern Yukon Territory are currently not well-documented. Lake sediments from Herschel Island (69°36’N; 139°04’W)...

This paper reports the results of an analysis of 508 sub-fossil carpometacarpi of swiftlets (Aves: Apodidae) recovered during archaeological excavations of the Great Cave of Niah in Sarawak, North-western Borneo. The bones date from 48 ky BP (ky BP: 103 calibrated years before present [1950]) to ...


Nd and Sr isotope characteristics of Quaternary Indo-Gangetic plains sediments: Source distinctiveness in different geographic regions and its geological significance
Quaternary sediments of the Himalayan foreland basin, known also as the Indo-Gangetic Plains, have been studied for their Sr and Nd isotopic geochemistry to constrain their sources and to infer their geological significance. The data show a large variation in the 87Sr/86Sr values and relatively a...
Earthflow sediment production and Holocene sediment record in a large Apennine catchment
Landscape evolution in active mountain chains can be dominated by gravitational slope movements. This is observed in a large portion of the Reno river catchment, Apennines, Italy, where weak rocks, such as clayshales, are subject to earthflows that control hillslope morphology and supply sediment...

Tectonic and climatic controls on late Quaternary bajada sedimentation along Narmada-Son Fault (NSF), Gujarat, Western India
An alluvial bajada has been recognized along a part of the active Narmada-Son Fault (NSF) and confined by the Karjan River on the eastern side and by the Madhumati River on western side. The bajada sequence exposed along the incised cliffs of various north flowing parallel streams has been studie...
