Greater Caspian Provenance Project 2019-2020
In this second phase, we carried out detrital zircon U-Pb age dating of two samples from each of the two sample datasets described in the first phase of this project in order to further characterise their source regions. The samples were derived from Quaternary alluvial sediments from the Amu Darya River and its tributary the Zarafshan; and from Bajocian and Albian shallow-marine sandstones from the Tuarkyr High, Turkmenistan, and the Volga River valley north of Volgograd, Russia, respectively.
Furthermore we carried out petrographic, conventional heavy mineral and detrital zircon U-Pb age analysis on six palaeo-Amu Darya River sands from the Upper Red Series of the Cheleken Peninsula of Turkmenistan. These analyses help to constrain the composition and provenance of reservoirs within the eastern South Caspian Basin, distinguish them from coeval Productive Series sandstones to the west, and provide insights into their reservoir potential.
Completed: November 2020.
