Structure, evolutionary context and chronological data of the Monforte de Moyuela Roman dam (Ebro Basin, NE of Spain)

open access: yesGeoarchaeology, Volume 38, Issue 4, Page 482-509, July/August 2023., 2023
Abstract The Monforte de Moyuela dam, also known as Ermita de la Virgen del Pilar dam, is a Roman reservoir built on a tributary of the Aguasvivas River (Ebro basin, Spain). A multidisciplinary study has been carried out to investigate this kind of Roman water infrastructure. It is the fifth‐highest dam (16.8 m) in the Iberian Peninsula and the seventh

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

open access: yesНижневолжский 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.

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

open access: yesGeochemistry, 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.

OPTICALLY STIMULATED LUMINESCENCE DATING OF THE UPPER HORIZON OF A SERBIAN LOESS-PALEOSOIL SEQUENCE USING QUARTZ

open access: yesStudia Universitatis Babeș-Bolyai Ambientum, 2021
Optically stimulated luminescence dating is widely used for establishing high-resolution chronologies for the Quaternary in paleoclimate research. Loess is an important archive of past climate changes on continents. In order to provide a first absolute chronology for Zemun loess paleosol sequence in Serbia, the single-aliquot-regenerative dose (SAR ...

Microscopy Observation of Samosir Formation Paleosoil, Tuktuk Sidaong, North Sumatera, Indonesia.

open access: yesJournal of Geoscience, Engineering, Environment, and Technology, 2021
Samosir is the islands that emerge and standing upon on Toba Caldera after it’s the last eruption at 74.000 years ago. Samosir Island known as the caldera floor that uplifts parallel with Toba’s caldera flooding. In this study, we have observed an outcrop in Tumutuk, Samosir Island that hypothesized as a lacustrine deposit, and we found a paleosoil ...

Characteristics and genetical environment of red paleosoils in the Amarguillo river tertiary basin (Toledo)

open access: yes, 1997
Several red paleosoils related to Tertiary deposits and showing a good development of calcic and argillic horizons are studied. According to their morphology and clay minerals a genetical change towards the top of the secuences has been identified.
