LATE PLEISTOCENE – HOLOCENE EXODYNAMICS AND SEDIMENTATION ENVIRONMENTS OF THE TUNKA RIFT VALLEY (SOUTHWESTERN BAIKAL REGION) BASED ON THE ANALYSIS OF LITHOLOGICAL AND PETROMAGNETIC FEATURES OF THE UPPER PALEOLITHIC DEPOSITS

open access: yesГеодинамика и тектонофизика
Sediments in the Tunka rift valley are deposited in high-energy geomorphic and lithodynamic processes. A number of Paleolithic sites are located here, but the number of archaeological finds in different parts of the rift varies greatly.

Crack Evolution and its Quantitative Analysis on Unsaturated Loess and Paleosoil

open access: yes
Abstract The alternating loess and loess paleo-soil layers exhibit distinct water contraction cracking behavior in the loess region. Investigating these characteristics is essential for projects in loess areas. This study focused on Q3 loess and loess samples, revealing the following key findings:(1) Cracking occurs in three stages: crack ...

Soils and Paleosoils of the Galápagos Islands: What We Know and What We Don't Know, A Meta-Analysis [PDF]

open access: yesPacific Science, 2014
Accessible information on Galapagos soils is very limited. Much of the existing, although still scarce, information is several decades old and not easily retrieved. The aim of this paper is to present a critical synthesis. Three local soil-forming factors (parent material, climate, and vegetation) are briefly highlighted, followed by a more detailed ...
