Tephrostratigraphy and tephrochronology of lakes Ohrid and Prespa, Balkans [PDF]
Biogeosciences, 2010 Four cores from Balkans lakes Ohrid and Prespa were examined for recognition of tephra layers and cryptotephras, and the results presented along with the review of data from other two already published cores from Lake Ohrid.

Late Quaternary tephrostratigraphy and cryptotephrostratigraphy of core MD012422: Improving marine tephrostratigraphy of the NW Pacific [PDF]
Quaternary Science Reviews, 2021 Abstract We investigated the deep-sea sedimentary sequence of core MD012422 corresponding to the last 350 ka (since marine isotopic stage, MIS 10) from off Shikoku Island, NW Pacific Ocean, and refined its tephrostratigraphy. We detected many tephras and cryptotephras and correlated them with terrestrial tephras on the basis of the major- and trace ...

Tephrostratigraphy of Jurassic-Cretaceous boundary beds of Western Siberia
Russian Journal of Earth Sciences, 2022 The age of tuffaceous interlayers, represented by tuffs and tuffites, which are common in the Upper Jurassic-Lower Cretaceous deposits of Western Siberia (the Bazhenovo, Tutleim and Frolov Formations), is discussed.

Late Quaternary tephrostratigraphy of southern Chile and Argentina
Quaternary Science Reviews, 2014 AbstractThe Southern and Austral Volcanic Zones of the Andes comprise 74 volcanic centres with known post-glacial activity. At least 21 of these have had one or more large explosive eruptions in the late Quaternary, dispersing tephra over vast areas.

Peuplements paléolithiques et paléoenvironnements pléistocènes dans le Massif central
Archéopages, 2022 During the last decades, the deployment of preventive operations related to ancient Prehistory in Auvergne permitted the exposure of many sites, whose contribution appears to be complementary to that of great historic locations.

Quaternary, 2022 The exact spatial and temporal behaviour of rapid climate shifts during the Last Glacial–Interglacial Transition are still not entirely understood. In order to investigate these events, it is necessary to have detailed palaeoenvironmental reconstructions

Frontiers in Earth Science, 2022 It is essential to establish the timing of past sector collapse events at a volcanic edifice to evaluate not only the evolution of the volcanic system but also potential volcanic hazards.

Geological evidence of strong tsunami manifestations on the Iturup Island (Kuril Islands) at last 3500 years [PDF]
Геосистемы переходных зон, 2023 The distribution of tsunami deposits in the lacustrine-swamp sections on the Kasatka Bay coast is analyzed. The main objects were a swamp formed on the place of overgrown lagoon-type lake located behind dune ridge, and a low swampy isthmus between ...

Coastal dunes of Urup Island (Kuril Islands, North-Western Pacific): palaeoclimatic and environmental archive [PDF]
Геосистемы переходных зон, 2022 The Late Holocene phases of aeolian processes have been reconstructed on the basis of dune fields construction. The palaeoenvironmental studies were targeted to following problems: 1) to determine the periods of higher and lower activity of aeolian ...
