Thrust collision zones with low slip rates along the plate boundary are significant areas of stress accumulation and prone to develop more destructive earthquakes with longer recurrence intervals. Such regions are often classified as low seismic risk if they lack continuous records of large earthquakes, such as the eastern Tibetan Plateau before th...

AbstractIn order to clarify the genesis of liquefaction folds (convolutions) developed at lithological boundaries in lacustrine sediments, such structures in three regions were compared. Folds in each region differ in morphology, composition of sediments, and the vertical gradient of their density and viscosity upon deformation. It is proposed to u...

AbstractThis paper presents results of multidisciplinary geochronologic, paleoseismic, and tectonophysical studies for local structures in the Sloboda tectono-dynamic intersection that is a segment of the junction between major tectonic structures in the East European Platform. These studies were conducted in the area of the Vitebsk–Surazh fault in...

peer reviewed / The western Qaidam Basin, NE Tibet contains numerous NW-SE-trending thrusts that extend over a distance of ∼300 km along the Altyn Tagh Fault and north of the Kunlun Range. However, little is known about the long-term seismo-tectonic evolution of this active thrust zone due to the absence of an extended paleoseismic record. We prese...

AbstractA study of a section exposed in a quarry near the village of Loukhi revealed a radial kame ridge composed of horizontally layered lacustrine sands with cross-bedded sand lenses and interlayers of siltstone with a 0.2- to 1.2-m-thick horizon of convolutions occurring as wide synclines, narrow anticlines, and pseudonodules. The lacustrine s...

Subaqueous mass failures that comprise slides, slumps and debris flows are a major process that transport sediments from the continental shelf and upper slope to the deep basins (both oceans and lacustrine settings). They are often viewed together with other natural hazards such as earthquakes, and can have serious socioeconomic consequences. It is...

AbstractThe Quaternary lacustrine complexes of two regions considered in this work formed in different paleogeographical conditions. In the Baltic crystalline shield, they accumulated as a result of the admission of thawing glacial waters in depressions, and this was favorable for the formation of a diverse lithological composition and sedimentary ...

AbstractThe history of lacustrine sedimentation in the Sevan depression is traced. The potential of using lacustrine sediments for the analysis of paleoclimate and neotectonic development of the region is shown. The long-term preservation of the lacustrine regime in the Sevan depression is mainly due to large lava flows that repeatedly create dams ...

A ca. 20 mm thick spherule bed representing Chicxulub impact ejecta deposits and marking the Cretaceous/Paleogene (K/Pg) boundary was recently discovered on Gorgonilla Island (Gorgona National Natural Park, Pacific of Colombia). This discovery represents the first confirmed record of the K/Pg event in Colombia, South America and the eastern Pacific...

AbstractA field study of sections of loose deposits in the western part of the Lake Sevan basin (Armenia) is conducted to investigate geoecological and paleogeographic features of existence and development of high-mountain lakes. The typical lithological patterns of significant lake transgressions are revealed and stratigraphic layers with numerous...
