Modern satellite gravity missions and ground gravimetry provide operational data models that can be used in various studies geology, tectonics, climatology, etc. In the present study, sedimentary basins southern part of East European Platform adjoining areas including Caucasus are studied by employing approach based on decompensative anomalies. The new model sediments, implying their thickness ...

Sea-level changes through the Quaternary era have provided recurrent opportunities for the biosphere to significantly shape the coastal geomorphology of eastern Africa. Key agents in this shaping have been the calcium carbonate-fixing biota that have constructed the oceanfacing fringing reefs and produced the extensive backreef sediments that form the limestone platforms, cliffs and terraces th...

A total of 100 shellfish samples from the Rosetta, Edku, El-Maadiya, Abo-Ki...

Paleontological data provide essential insights into the processes shaping the spatial distribution of present-day biodiversity. Here, we combine biogeographic data with the fossil record to investigate the roles of parallelism (similar diversities reached via changes from similar starting points), convergence (similar diversities reached from different starting points), and divergence in shapi...
