Rocks in the field

My PhD thesis


Research of Annique van der Boon

The Birth of the Paratethys Sea
The Maikop series are composed of a thick succession of black shales, and are considered the most important source rock for hydrocarbons in the Caspian basin. The type section of this formation is located near the city of Maykop in Russia, north of the Greater Caucasus. Corresponding anoxic sediments can be traced in a vast area from Austria to China. Deposition of these sediments is linked to anoxic conditions that prevailed since the birth of the Paratethys and are related to decreased basin circulation. Due to the lack of (micro) organisms or ash layers, the onset of Maikop deposition has not been dated accurately so far. The Maikop is presently assumed to be of Oligocene to Miocene age.

Precise dating of the start of Maikop sedimentation could aid in understanding the role of tectonics and climate change on the onset of anoxia in the Paratethys basin, as both have affected the region during the Paleogene. The Arabia-Eurasia collision has caused uplift, which could have caused a restriction in interaction with the Tethys Sea further south. Alternatively, basin restriction might have been caused by a major glacio-eustatic regression, associated with the transition from greenhouse to icehouse climate around the Eocene-Oligocene transition (EOT).

Furthermore, in the Talysh Mountains in Azerbaijan, Eocene volcanic rocks are present underneath the anoxic sediments. During my MSc research, these volcanics were also sampled. Geochemical analyses have given rise to more questions about the tectonic setting in which these volcanics were deposited. 
This research requires a comparison with the Eocene volcanics of the Urumieh-Dokhtar Magmatic belt in Iran, where we will hopefully soon be able to go for extensive sampling.
