The sources are dominated by contributions from the Higher Himalaya (HH) with subordinate supply from the Lesser Himalaya (LH). However, on millennial timescale, there are evidences of variations in the provenance of sediments related to climatic change...

[1] Along the southern Himalayan topographic front, the Indian summer monsoon modulates erosive processes and rates. To investigate the influence of topography and relief on rainfall generation and resultant erosion, we processed satellite rainfall amounts for the last 8 years (1998–2005) from the Tropical Rainfall Measurement Mission (TRMM). Based upon a spatial resolution of 5 5 km for the Hi...

Himalayan rivers have very unusual Sr characteristics and their budget cannot be achieved by simple mixing between silicate and carbonate even if carbonates are radiogenic. We present Sr, O, and C isotopic data from river and rain water, bedload and bedrock samples for the western and central Nepal Himalaya and Bangladesh, including the monsoon season. Central Himalayan rivers receive Sr from s...

biostratigraphy of bahram formation succession, with 359.8 meter thickness, in the sardar section (north of kerman, central iran) is done in this study. bahram formation is mostly composed of limestones (with a lesser amount of sandstones), and conformably overlies the top sandstone beds of the padeha formation. but, the upper boundary with the hutk formation (late tounaisian) is disconformable...

Testing models that link climate and solid Earth tectonics in mountain belts requires independent erosional, structural climatic histories. Two well-preserved stratigraphic sections of the Himalayan foreland basin are exposed NW India. The Jawalamukhi (13–5 Ma) Joginder Nagar (21–13 dated by magnetostratigraphy span a period significant change tectonic evolution. We combine sediment geochemistr...
