Paleoseismology of a Major Crustal Seismogenic Source Near Mexico City: The Southern Border of the Acambay Graben

Tectonics, Volume 42, Issue 6, June 2023., 2023
Abstract The Trans‐Mexican Volcanic Belt is an active continental volcanic arc related to subduction along the Middle America trench. It is characterized by intra‐arc extension resulting into several major arc‐parallel active fault systems and tectonic basins.

Highly Contrasted Geochemical Pattern in Sediments of the Okavango Delta, Botswana Driven by Dust Supply, Hydrological Heritage and Biogeochemical Reactions

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 6, June 2023., 2023
Abstract The Okavango Delta in North Botswana is a hot‐spot of biodiversity within the semi‐arid central part of the South African plateau. This endorheic ecosystem is highly dependent on the annual flood that brings freshwater from the highlands of Angola to the North.

The Identification of Wool by the Number of Keratinolytic Microorganisms in the Ground of Ancient and Medieval Burials

Нижневолжский археологический вестник, 2018
The paper describes the method for determining the initial presence of wool products in the burial rite of several cultures of the Bronze Age and the Middle Ages. The method is based on the analysis of the number of keratinolytic fungi in soils.

Electron Accepting Capacities of a Wide Variety of Peat Materials From Around the Globe Similarly Explain CO2 and CH4 Formation

Global Biogeochemical Cycles, Volume 37, Issue 1, January 2023., 2023
Abstract In organic soils, the availability of terminal electron acceptors (TEAs) determines the ratio of CO2 to CH4 formation under anoxic conditions. While the importance of electron accepting capacities (EACs) of organic matter is increasingly acknowledged, redox properties of organic matter have only been investigated in a limited set of peat and ...

Changing nature of Pleistocene interglacials - is it recorded by paleosoils in Hungary (Central Europe)?

Hungarian Geographical Bulletin, 2015
Based on stable isotope analyses of worldwide reference curves, it has long been apparent that duration, intensity and climatic conditions of Pleistocene interglacial periods were significantly diverse.

Active Back‐Arc Thrust in North West Java, Indonesia

Tectonics, Volume 41, Issue 7, July 2022., 2022
Abstract The Java Back‐arc Thrust scars the entire back‐arc area of Java Island, but the faults' nature, timing, and activity remain partly elusive. Characterizing the structure and activity of the seismogenic Java Back‐arc Thrust (historical earthquakes up to 7 Mw) is a cornerstone to evaluate associated geohazards.

Subkurgan Paleosoils of the Lower Volga Steppes as Indicators of Climate Dynamics over an Historical Epoch

Поволжская археология, 2013
The studies of paleosoils buried beneath burial mounds of the Early, Middle, and Late Sarmatian time (4th c. BC to 4th c. AD) were carried out in the dry and desert steppes of the Lower Volga river area (the Volga and Yergenino uplands, the Caspian ...
