In this Letter, we experimentally investigate the collapse of initially dry granular media into water and the subsequent impulse waves. We systematically characterize the influence of the slope angle and the granular material on the initial amplitude of the generated leading wave and the evolution of its amplitude during the propagation. The experiments show that whereas the evolution of the le...

Anthracoporella algal mounds, up to 22 m thick, occur within the cyclic sequences of the Lower Pseudoschwagerina Limestone (uppermost Carboniferous), Carnic Alps (Austria). Their depositional environment lay between the wave base and the base of the photic zone. The algal mounds are overlain by dark, well-bedded, cherty wackestones and packstones. The cherty limestones contain cephalopods, thic...

There have been presented the results of study a thick (no less than 2–3 km), extended (for more 200 km) volcanogenic formation (Tsetsen-Uul or Yargait) in south Zavkhan terrane Central Asian fold belt. The is an assemblage frequently intercalating effusive rocks subalkaline basalt-andesite-dacite-rhyolite series, their tuffs, tuffites, ignimbrites, and terrigenous rocks. Felsic dominate over b...

Abstract We investigated four subaerial (paleo)lacustrine landforms at the north‐eastern shoreline of Schweriner See, Germany. These included two beach ridges, one nearshore bar and a silting up sequence located close to fossil cliff, which marks former maximum extent See. used luminescence profiling with SUERC portable OSL device (POSL) on all sediment sequences in combination sedimentological...

Abstract. High-resolution geochronology is essential for determining the growth rate of volcanoes, which one key factors establishing periodicity volcanic eruptions. However, there are less high-resolution eruptive histories (> 106 years) determined long-lived submarine arc complexes than subaerial complexes, since volcanoes far more difficult to observe ones. In this study, and major-elemen...

This study analyses the morphological changes induced by eruptive activity at Stromboli volcano (Italy) during and after events occurring July–August 2019. period was characterized intense (two paroxysmal explosions, a two-month-long lava emission, more frequent “ordinary” explosive activity) that produced significant within region known as Sciara del Fuoco, located on most unstable, north-west...

This work evaluates growth strata adjacent to the Bakio Diapir in Basque Pyrenees, aiming discuss application of halokinetic-sequence concepts, mainly developed shallow-water subaerial environments, deepwater depositional settings. is one few exposed passive diapirs with both synkinematic carbonate and siliciclastic strata. Thus, considering that large hydrocarbon producing areas are located sa...
