The Peshawar basin is situated along the junction of the northern margin of the IndoGangetic foredeep and the southern margin of the Hindu Rush-Himalayan Ranges. During the late Cenozoic, southward encroachment of tectonic disruption into the foredeep terminated molasse deposition and delineated the Peshawar intermontane basin through uplift of the Attock Range along the southern margin of the ...

We analyze both new and previously published paleomagnetic records of secular variation (PSV) from Lake Superior sediment cores and compare these records to correlated rhythmite (varve) thickness records to determine post-glacial sedimentation rates and to reassess the termination of glaciolacustrine varves in the basin. The results suggest that offshore sedimentation rates have exhibited consi...

The paper presents a part of the scientific activity of GEOECOMAR team during the IAEA project RER 2/003 Marine Environmental Assessment of the Black Sea Region, on board of R/V “Prof. Vodyanitskyi” and in laboratories. The Black Sea presents different sedimentological and geochemical characteristics in the eastern and western sub-basins. Whole sections of the Upper and Middle Holocene sediment...

The operational cycle of a storm water quality control basin can be divided into the waiting period between events and the filling and draining period during an event. In this study, an inherent overflow risk is defined as the probability of having a large event exceed the basin storage capacity. Such a probability is prescribed by the basin storage capacity and the local distribution of rainfa...

In erosion and sedimentation problems, estimating the range of significant stream flows to include when computing sediment transport can prove challenging in ungauged or under-gauged basins. This paper describes an event-based model incorporating a geomorphologic instantaneous unit hydrograph and stochastic descriptions of peak flows and frequency of storm events from nearby reference watershed...

Architecture of slopeand basin-floor-fan systems in growth-faulted subbasins along the south Texas Gulf Coast developed as a result of interplay between synsedimentary tectonics and sedimentation during third-order sea-level lowstands. These subbasins, or intraslope basins, have not been adequately explored for their slope and basin-floor-fan potential, as have the intraslope basins in salt-dom...

An integrated lithologic, paleontologic, and multi-proxy geochemical study of the Middle Devonian Oatka Creek Formation, a black shale in the northern Appalachian Basin, indicates that a number of different factors contributed to organic carbon-rich black shale deposition. Conditions leading to this organic-rich sedimentary deposit were ultimately controlled by a relative sealevel rise, dominan...

[1] The northwest Argentine Andes constitute a premier natural laboratory to assess the complex interactions between isolated uplifts, orographic precipitation gradients, and related erosion and sedimentation patterns. Here we present new stratigraphic observations and age information from intermontane basin sediments to elucidate the Neogene to Quaternary shortening history and associated sedi...
