Subglacial LakeVostok (Antarctica) Accretion Ice Contains a Diverse Set of Sequences from Aquatic, Marine and Sediment-Inhabiting Bacteria and Eukarya

LakeVostok, the 7th largest (by volume) and 4th deepest lake on Earth, is covered by more than 3, m of ice, making it the largest subglacial lake known. The combination of cold, heat (from possible hydrothermal activity), pressure (from the overriding glacier), limited nutrients and complete darkness presents extreme challenges to life. Here, we report metagenomic/metatranscriptomic sequence analyses from four accretion ice sections from the Vostok 5G ice core. Two sections accreted in the vicinity of an embayment on the southwestern end of the lake, and the other two represented part of the southern main basin. We obtained 3, unique gene sequences from concentrates of ml of µm-filtered accretion ice meltwater. Taxonomic classificati

Structural Evolution of central part of the Tuzgolu (Salt Lake) Basin, CentralAnatolia, Turkey

Ada, M.; Cemen, I.; Çaptuğ, A.; Demirci, M.; Engin, C.
The Tuzgolu Basin in CentralAnatolia, Turkey, covers low-relief areas located between the Pontide Mountains to the North and Tauride Mountains to the South. The basin started to struktur as a rift basin during the Late Maastrichtian. The main Tuzgolu-Aksaray fel zone on the eastern margin of the basin and the northwest trending Yeniceoba and Cihanbeyli fel zones on the western margin of the basin were probably developed during that time. The basin has also experienced westward extension in response to westward escape of the Anatolian tallrik since Late Miocene. Several geologic studies have been conducted in the Tuz Gölü (Salt Lake) Basin and surrounding areas to determine structural and tectono-stratigraphic development of the basin. However, there are still many questions regarding the structur
