Pedologický a paleopedologický výzkum jihozápadní části pohoří Sabaloka // Pedological and Paleopedological Investigation of South-western Part of Jebel Sabaloka [PDF]

open access: yesPražské Egyptologické Studie, 2015
The main aim of the geoarchaeological research of Sabaloka in the 2014 season was the paleopedological mapping around the archaeological sites excavated in the past seasons. Generally, four main types of soils or paleosoils were described. These soils

A detailed paleomagnetic and rock-magnetic investigation of the Matuyama-Bruhnes geomagnetic reversal recorded in tephra-paleosol sequence of Tlaxcala(Central Mexico)

open access: yesFrontiers in Earth Science, 2015
Geomagnetic reversals are global phenomena, for about 50 years the paleomagnetists attempted to acquire as many detailed records as possible using the magnetic memory of sediments and lava flows.

Satellite Geodesy Reveals Shallow, Transient Magma Intrusions at Sotará Volcano, Colombia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Sotará is a little‐known andesitic‐dacitic stratovolcano in southwestern Colombia. Although there are no recorded historical eruptions, the volcano shows clear evidence of geothermal activity, deformation, and volcano‐tectonic seismicity. Its remote location and rugged terrain pose challenges for access and routine monitoring.

Shale Tectonics in the Hyperextended Continental Margin of the Niger Delta

open access: yesTectonics, Volume 44, Issue 7, July 2025.
Abstract Based on the interpretation of a large seismic data set, we provide a comprehensive description of the structures affecting the entire Niger Delta, from the onshore domain to the deep‐offshore. The shale‐dominated delta lies on a divergent segment of the west African passive margin.

Secondary carbonates in loess-paleosoil sequences: a general review

open access: yesOpen Geosciences, 2011
Abstract The literature dealing with secondary carbonates in loess-paleosoil sequences is in many cases ambiguous, which means that different concepts are used for the same features, whereas certain concepts referring to different types are used as collective nouns.
