Origin and Characteristics of the Crude Oils and Condensates in the Callovian-Oxfordian Carbonate Reservoirs of the Amu Darya Right Bank Block, Turkmenistan

Lithosphere, 2022
The Amu Darya Right Bank Block is located northeast of the Amu Darya basin, a large petroliferous sedimentary basin, with abundant natural gas resources in carbonate rocks under the ultra-thick gypsum-salt layer.

MICROFORAMINIFERS OF THE CALLOVIAN AND CRETACEOUS SEDIMENTS OF UKRAINE [PDF]

Geological Journal, 2015
For the first time in Ukraine in Callovian and Cretaceous sediments the microforaminifers were found. They were established during the study of Mesozoic sediments palynocomplexes of 17 outcrops and wells Volyno-Podolska plate, Ukrainian Shield, the outstirts of Donbass, Priazov, Black Sea basin and the Crimea.

Stable isotope (δ18O and δ13C) sclerochronology of Callovian (Middle Jurassic) bivalves (Gryphaea (Bilobissa) dilobotes) and belemnites (Cylindroteuthis puzosiana) from the Peterborough Member of the Oxford Clay Formation (Cambridgeshire, England): Evidence of palaeoclimate, water depth and belemnite behaviour [PDF]

, 2014
Incremental δ18O and δ13C signals were obtained from three well-preserved specimens of Cylindroteuthis puzosiana and from three well-preserved specimens of Gryphaea (Bilobissa) dilobotes from the Peterborough Member of the Oxford Clay Formation ...

Middle–Upper Jurassic palynology of the South Sallum well, North Western Desert, Egypt

Egyptian Journal of Petroleum, 2018
Palynological analyses have been carried out on some samples of Middle–Upper Jurassic from the South Sallum well, North Western Desert, Egypt. A refinement of the original chronostratigraphy has been suggested and the stages of Bathonian – Callovian and ...

Sea surface temperature contributes to marine crocodylomorph evolution [PDF]

, 2014
During the Mesozoic and Cenozoic, four distinct crocodylomorph lineages colonized the marine environment. They were conspicuously absent from high latitudes, which in the Mesozoic were occupied by warm-blooded ichthyosaurs and plesiosaurs.
