karyotype of river loach turcinoemacheilus kosswigi bănărescu and nalbant, 1964 (cypriniformes, balitoridae) from the euphrates river, turkey

karyotype of river loach turcinoemacheilus kosswigi from the euphrates river, turkey was investigated using conventional giemsa-staining and c-banding. two females and two males were analyzed. diploid chromosome number was 2n= 50 in all specimens. the karyotype consisted of four pairs of metacentric (m), seven pairs of submeta (sm)-subtelocentric (st) and 14 pairs of acrocentric (a) chromosomes...

Location of the River Euphrates in the Late Miocene; dating of terrace gravel at Shireen, Syria

We report gravel of the River Euphrates, capped by basalt that is Ar-Ar dated to ∼9 Ma, at Shireen in northern Syria. This gravel, preserved by the erosion-resistant basalt, allows us for the first time to reconstruct the history of this major river during the Late Miocene. In response to progressive regional surface uplift, the Euphrates extended SE by ∼800 km between the early Middle Miocene,...

Mineralogy and geochemistry of major, trace and REE elements, Pirashkaft Bauxite Deposits, Mamasani, Fars Province

The Pirashkaft bauxite deposit is located in north of the Paskuhak anticline in the Fars Province. The bauxite deposit present between Sarvak and Gurpy Formations, and formed during the Late Turonian time as a consequent of the Laramid orogeny phase. According to the geological investigations, the Pirashkaft bauxite is  Karstic type. The residual ore studied in the Pirashkaft can be classified ...
