Hydrocarbon systems and oil and gas potential prospects of the Anabar-Lena trough

Georesursy, 2017
The Anabar-Lena trough is one of the least geologically studied areas on the Siberian Platform. A few wells drilled here have not yet revealed direct signs of its oil bearing. However, indirect data indicate that this region can be very prospective. This

Seismogeological structure model of the Anabar-Olenek region

Georesursy
The velocity characteristics of the Upper Proterozoic-Phanerozoic sedimentary cover of the AnabarOlenek region were studied, in particular, the bimodal character of the distribution interval P-wave velocities was established.

Geochemical background of Berezovsky depression oil and gas potential (eastern Siberia)

Georesursy
Berezovsky depression, located on the northeast of the Pre-Patom foredeep, is a promising target for hydrocarbon prospecting, as evidenced by oil and gas shows established while drilling, the presence of structures and natural reservoirs.

Phytoplankton dynamics from the Cambrian Explosion to the onset of the Great Ordovician Biodiversification Event: a review of Cambrian acritarch diversity [PDF]

, 2015
Most early Palaeozoic acritarchs are thought to represent a part of the marine phytoplankton and so constituted a significant element at the base of the marine trophic chain during the ‘Cambrian Explosion’ and the subsequent ‘Great Ordovician ...

Variations of Th/U values in Vendian clayey rocks of north-east East-European Platform and Middle and Southern Urals as reflection redox status of sedimentary basins

Литосфера, 2017
Earlier, we considered the features of the redox changes in the near-bottom layer of water in the sedimentation basins that existed during the Late Riphean and Vendian in the eastern and northeastern (in modern coordinates) margins of the Baltic.
