Journal of Quaternary Science, Volume 38, Issue 1, Page 107-122, January 2023., 2023 Abstract Small mountain lakes are natural archives for understanding long‐term natural and anthropogenic impact on the environment. This study focused on long‐term (last ca. 13 000 years) vegetation changes and sedimentary processes in the catchment area of Lake Planina pri jezeru (1430 m a.s.l.) by using mineralogical, geochemical and palynological ...

Strength and energy consumption of inherently anisotropic rocks at failure [PDF]
, 2021 Using a discrete-element approach and a bonding interaction law, we model and test crushable inherently anisotropic structures reminiscent of the layering found in sedimentary and metamorphic rocks. By systematically modifying the level of inherent anisotropy, we characterize the evolution of the failure strength of circular rock samples discretized ...

Frontiers in Earth Science, 2022 Hydrothermal fluid is one of the factors controlling Archean buried hill reservoirs in Bozhong 19-6. However, there are no clear studies focusing on the influence of hydrothermal alteration products and their lithological characteristics on reservoirs ...

Zoo Biology, Volume 41, Issue 6, Page 533-543, November/December 2022., 2022 Stages of tadpole development from Week 1 to Week 8 in Pickersgill's reed frogs bred in captivity at Johannesburg Zoo, South Africa. Abstract Globally, the threats of habitat loss and disease on amphibian survival have necessitated the creation of ex‐situ insurance populations as a conservation tool. We initiated a captive breeding project to create an

Craton Destruction Induced by Drastic Drops in Lithospheric Mantle Viscosity
Earth and Space Science, Volume 9, Issue 12, December 2022., 2022 Abstract The disruption of the mantle roots of cratons is common after cratonization. Craton destruction, which is characterized by severe lithospheric thinning, extensive thrust and extensional deformation, basin filling, and intense thermal activities, is relatively rare and is generally attributed to intensely reduced viscosity contrasts between the

Геодинамика и тектонофизика, 2023 Thermochronological reconstructions of the Zagan metamorphic core complex were carried out using samples from the central part of the core, mylonite zone detachment and lower nappe with U/Pb zircon dating, 40Ar/39Ar amphibole and mica dating, and apatite

Repeating Low Frequency Icequakes in the Mont‐Blanc Massif Triggered by Snowfalls
Journal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022 Abstract Deformation mechanisms of glaciers are highly sensitive to basal temperature; the motion of temperate glaciers is dominated by basal slip while cold‐based glaciers deform mainly by internal creep. While basal slip is usually aseismic, unstable slip sometimes occurs and can be detected by seismometers.

Adsorption Science & Technology, 2022 The North Qilian orogenic belt is a typical area of “cold” subduction of the early Paleozoic oceanic plate, forming a series of high pressure and low temperature metamorphic rock assemblages. Among them, eclogite is a kind of protolith, which is basaltic

Tectonics, Volume 41, Issue 12, December 2022., 2022 Abstract Orogenic wedges are common at convergent plate margins and deform internally to maintain a self‐similar geometry during growth. New structural mapping and thermochronometry data illustrate that the eastern Greater Caucasus mountain range of western Asia undergoes deformation via distinct mechanisms that correspond with contrasting lithologies ...

Structure, stability, and tsunami hazard associated with a rock slope in Knight Inlet, British Columbia [PDF]
Natural Hazards and Earth System Sciences, 2015 Rockfalls and rockslides during the past 12 000 years have deposited bouldery debris cones on the seafloor beneath massive rock slopes throughout the inner part of Knight Inlet.
