Recent discoveries define a global scale fluid reservoir residing within the uppermost igneous oceanic crust, a region of seafloor that is both warm and may harbor a substantial biosphere. This hydrothermal fluid reservoir ...

We report new results of multiple EMP analyses of sorosite from the Baimka Au-PGE placer deposit, western Chukotka, northeastern Russia. It occurs as (1) relatively large (0.24).4 mm) euhedral, cryptically zoned hexagonal ...

Nucleation and development of microrelief and fragmentation of coating under tensile extension of polymer films coated with a thin rigid layer is studied, and the mechanisms responsible for the development of both types ...

Hypervelocity impacts of cosmic projectiles larger than ˜200 m diameter are capable of forming complex craters on Earth. At these craters, shock loading, shock damage, and excavation flow are followed by a gravity-driven ...

Callovian stratigraphy is usually based on ammonites, while foraminiferal assemblages are correlated with the ammonite scale. Precisely this approach was used for elaborating the Callovian stratigraphic scale for the Russian ...

Data on changes in the taxonomic composition of planktonic and benthic foraminifers across the Cretaceous-Paleogene boundary are presented. Extinction events in the highly specialized planktonic group were most remarkable. ...

In the northeastern Peri Tethys, the Goryachii Klyuch facies of the upper Paleocene are much more widespread than it was believed before. The facies correspond to dark colored, predominantly carbonate-free sediments bearing ...
