ZusammenfassungDer Van-See hat ein Volumen von 607 km3 und eine maximale Wassertiefe von 451 m. Er liegt in einer tektonisch aktiven Zone und ist von Vulkanen umgeben. Drei physiographische Provinzen lassen sich ausscheiden: Schelf, Seeabhang und Seebecken. Der Schelf besteht weitgehend aus ehemaligen Flußtälern und alluvialen Ebenen mit ausgeprägter karstartiger Topographie, Deltaschüttungen und mäandrierenden Flußtälern. Schelf- und Beckensedimente setzen sich zusammen aus unverfestigten… 

Analysis of a fragmentary diatom record from Lake Van (Turkey) reveals substantial lake-level variability during previous interglacials MIS7 and MIS5e

Ancient lake sediments provide opportunities to reconstruct aquatic ecosystems during previous interglacials. In the summer of 2010, the ICDP project PALEOVAN drilled a complete succession of the

Comparison of Recent Siliceous and Carbonate Mat Development on the Shore of Hyper-Alkaline Lake Van and Mt. Nemrut Soğuk Lake, NE Anatolia, Turkey

This article focuses on the molecular geochemistry of previously unreported carbonate- and siliceous-mat assemblages at two adjacent lake-shore environments. The first study area, on the Lake Van

Sedimentary evolution and environmental history of Lake Van (Turkey) over the past 600 000 years

The lithostratigraphic framework of Lake Van, eastern Turkey, has been systematically analysed to document the sedimentary evolution and the environmental history of the lake during the past ca 600

Microbially mediated carbonates in the Holocene deposits from Sarliève, a small ancient lake of the French Massif Central, testify to the evolution of a restricted environment

Both the mineralogy and facies of lacustrine bio‐induced carbonates are controlled largely by hydrological factors that are highly dependent upon climatic influence. As such they are useful tools in

Quaternary History of Lake Tahoe, California-Nevada

Lake Tahoe, California-Nevada, occupies a graben near the crest of the Sierra Nevada. The lake basin was formed by faulting and volcanism about 2 m.y. ago and contains more than 400 m of sediments.

Depositional Systems and Shelf-Slope Relations on Cratonic Basin Margin, Uppermost Pennsylvanian of North-Central Texas

The Eastern shelf was a constructional platform developed on the margin of the sediment-starved Midland basin during Late Pennsylvanian and Early Permian times. A mixed terrigenous-carbonate

Delta: Term and Concept

Some confusion exists in the minds of many geologists regarding the three-dimensional geological setting of a delta and its offshore counterparts which together comprise a dynamic system. In part,

Sediment Ponding in the Deep Sea

Echo soundings made over the North Atlantic Ocean and the Mediterranean Sea, using sound pulses from 0.2 to 1 millisecond long, exhibit evidence that several horizontal layers of sediment extend

Congo Submarine Canyon and Fan Valley

Seventeen transverse profiles of the inner 460 km of the Congo Canyon and the Congo Fan Valley were made during a 4-day study in June 1972. These profiles show that the canyon is V-shaped with side
