The evolution stages of the lacustrine-boggy sedimentary environments and the role of the climatic and volcanic factors were reconstructed on the basis of complex stratigraphic (botanical, palynological, and diatom analyses and tephrostratigraphy) and radiocarbon studies of the peat lands on Rasshua Island during the middle-late Holocene. The stages of the landscape evolution and the time of their reorganization were determined.  相似文献

We provide data concerning a weak phreatic eruption of Ekarma Volcano on Ekarma Island, in the Kurils, in June 2010. The ash plumes did not rise higher than 3 km above sea level. A preliminary estimate of the volume of erupted resurgent material (mostly tephra) is on order 2 × 105 m3. Reconstruction of the volcano??s history and the dynamics of its eruptive activity for the last 4500?C5000 years suggests that a larger eruption can occur during the next few decades that will discharge juvenile pyroclastics and/or lava.  相似文献

This paper contains lithostratigraphic and chronometric (radiocarbon dating) data on one of the regions on the Karelian coast of the White Sea obtained in the course of investigation of sedimentary sections from recent lake basins, which were separated at different times from the sea due to uplift of the glacioisostatic crust of the Earth. They were used as a basis for stratigraphic subdivision of marine and fresh water sediments and for reconstruction of the White Sea coast level change during the Late Pleistocene-Holocene near the Settlement of Kuzema, Karelia.  相似文献
