Geological Journal, EarlyView.This study reveals that the underexplored Benin Basin features a narrow shelf and steep slope, which promoted the development of multi‐phase, stacked channel‐lobe complexes. These gravity flow deposits, further enhanced by bottom current reworking, reveal a significant undiscovered Upper Cretaceous stratigraphic play with considerable petroleum ...

The oldest ceratosaurian (Dinosauria: Theropoda), from the Lower Jurassic of Italy, sheds light on the evolution of the three-fingered hand of birds [PDF]
PeerJ, 2018 The homology of the tridactyl hand of birds is a still debated subject, with both paleontological and developmental evidence used in support of alternative identity patterns in the avian fingers.

Geological Journal, EarlyView.The rhyolitic ignimbrite and K‐feldspar granite porphyry from the Wangmushan mining district, northern Fujian yield ages of 173.8 ± 0.8 and 102.6 ± 0.4 Ma, respectively. Geochemical data, zircon trace elements, whole‐rock Sr–Nd–Pb isotope data, and zircon Hf isotopic compositions indicate that the rhyolitic ignimbrite originated from partial remelting ...

Identification of hard-to-recover reserves of Ugra oil
Геофизический журнал, 2019 More than 70 % of the reserves of Yugra oil fields, which are in development and at various stages of study, are classified as hard-to-recover (HTR). Active involvement in the development of HTR will prevent the decline and stabilize production in the ...

Journal of Quaternary Science, EarlyView.ABSTRACT Understanding Earth‐surface processes along the fringes of large ice sheets is integral to deciphering cold‐region environmental variability and anticipating slope instability under climate change. We investigate the Meseta Chile Chico, a volcanic plateau in the central Patagonian Andes, located at the eastern margin of the former Patagonian ...
