Microbiology of a hypersaline oil reservoir located in Central Africa was investigated with molecular and culture methods applied to preserved core samples. Here we show that the community structure was partially acquired during sedimentation, as many prokaryotic 16S rRNA gene sequences retrieved from the extracted DNA are phylogenetically related to actual Archaea inhabiting surface evaporitic...

We find net sedimentation rate[(13–200) lm/yr in the Aeolis Dorsa region, Mars, using the frequency of crater–river interactions. This sets a lower bound of 1–20 Myr on the total interval spanned by fluvial activity, which we correlate to the Noachian–Hesperian transition. The main uncertainty is the impact flux at the time of deposition. This result rules out basin-filling by a single catastro...

The Upper Bajocian- Lower Bathonian succession in the Kopet-Dagh Basin of NE Iran represents fluvio-deltaic to turbidite deposits. The Kashafrud Formation provides an excellent opportunity to study the interplay between deep-water sedimentation and syndepositional tectonic subsidence (or uplift) in the region. The effects of these processes caused sea-level changes, variation in depositional se...

Flood disaster is considered as a major natural hazard due to its devastatingeffects on the affected areas. Determining the flood vulnerable areas is important fordecision makers in order to perform planning and management activities. GeographicalInformation System (GIS) is integrated with Multi Criteria Decision Analysis (MCDA)used to analyze the flood vulnerable areas. The aim of this researc...

10 Recent sedimentation along the Hikurangi subduction margin off northeastern New Zealand is 11 investigated using a series of piston cores collected between 2003 and 2008. The active Hikurangi 12 Margin lies along the Pacific-Australia subduction plate boundary and contains a diverse range of 13 geomorphologic settings. Slope basin stratigraphy is thick and complex, resulting from sustained h...

Abstract In its subsurface, the Browse Basin on Australian Northwest Shelf accommodates one of largest Miocene–Pliocene carbonate platform provinces Earth. This study presents a comprehensive three-dimensional (3-D) documentation and investigation Neogene carbonates based analysis 15 3-D seismic reflection volumes covering ca. 33,000 km2 22 industry boreholes. Eight basin-wide marker horizons t...

The paper examines sediment yield and its response to catchment disturbance and environmental variables in the Upper Ž . Yangtze basin, where the attention of environmentalists has been drawn to the Three Gorges Project TGP . Information about the source and conveyance of sediment from the catchment area to the Three Gorges Reservoir has implications for management strategies. Methodologies for...

Abstract The origin of the passive margin forming paleo-Pacific western edge ancestral North American continent (Laurentia) constrains breakup Rodinia and sets stage for Phanerozoic evolution Laurentia. Windermere Supergroup in southern Canadian Cordillera records rift-to-drift sedimentation form a prograding continental deposited between ~730 570 Ma. New U-Pb detrital zircon analysis from samp...

Over the last 20 years, the geoarchaeology of ancient harbours has been a very active area of research around the Mediterranean basin, generating much palaeoenvironmental data from many sites, including estimations of sedimentation rates, the height of the ancient sea-level at different dates and palaeo-geographical reconstructions. Combining this information has proved a major challenge. This ...

a r t i c l e i n f o This study takes a comprehensive approach to characterizing the isolation sequence of Heimerdalsvatnet, a coastal lake in the Lofoten Islands, northern Norway. We use established methods and explore new techniques to assess changes in marine influence. Bathymetric and sub-bottom profiles were acquired to examine basin-wide sedimentation and a 5.8 m sediment core spanning t...
