This archeoseismologic study focuses on the Leukos settlement that thrived west coast of forearc island Karpathos in 4th−6th centuries CE. The onshore site occupies eastern rim offshore Basin, deepest Aegean basin, a sector Hellenic typically regarded as seismically insignificant. Investigations faulting, sedimentary processes, and secondary earthquake effects (hydraulic fracturing, liquefactio...

Abstract Pre-Holocene landslides and tsunami deposits are commonly observed on continental margins oceanic islands. However, scarce evidence has thus far linked pre-historic submarine to particular events. This work focuses an 839 km 3 landslide that occurred in the South China Sea at 0.54 Ma. Bathymetric restorations show paleoshoreline Ma was 180–580 south of its present-day location. In such...

Since the time of Darwin (1859) and Wallace (1869), islands have been regarded by scientists as a prime target for scrutinizing the forces that may influence evolution and diversification and important elements in biogeographic studies. This research aims to scrutinize whether and to what extent the composition and structure of past mammal insular faunas and their changes through time may provi...

Neogene syn-and post-orogenic sedimentary rocks in Sulawesi are important to understand the history of collision Australian continental crust with SE Asia. However, they have received relatively little attention, and generally been considered be molasse-type deposits similar characteristics across Sulawesi—the Celebes Molasse. New field sedimentological observations, results from heavy mineral ...

Abstract The eastern Anti-Atlas of Morocco represents one the most completely exposed and perfectly documented biostratigraphic records entire Devonian worldwide. Paleogeographically it is clearly differentiated into shallow basins, pelagic platforms, land areas which are newly defined illustrated, from top Middle Devonian, other middle Famennian as two characteristic intervals. dominant paleog...
