Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Aux origines africaines de l’homme

Afrique Archéologie Arts, 2010
During the past decade, the palaeontological history of man has been considerably enriched by the discovery of several potential ancestors of humans, gorillas and chimpanzees in Africa allowing a better reconstruction of our phylogenetic tree (even ...

The late Holocene palaeoenvironment in the lake Njupi area, west Cameroon : implications regarding the history of lake Nyos [PDF]

, 1997
Le lac Njupi, au sein de la ligne volcanique du Cameroun, s'est constitué par barrage d'une dépression à 1 km à l'est du lac Nyos. Les deux sondages du lac Nyos analysés ont traversé les sédiments déposés au marges du lac.

Microbial mats in dinosaur ichnocoenoses

Sedimentology, EarlyView.
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

Palaeoenvironments and landscape diversity in Egypt during the Last Interglacial and its implications on the dispersal of Homo sapiens

Journal of Maps, 2022
The Last Interglacial period is important for the spread of humans from Africa to Eurasia. Significant wetter climatic conditions allowed humans to live in the present-day arid landscape in Northeastern Africa.

Development of Holocene lacustrine microbialites on the Iberian Peninsula: Insights into environmental and depositional controls using X‐ray CT and petrography

Sedimentology, EarlyView.
ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

The complete lithostratigraphic section of the geothermal wells in Rittershoffen (Upper Rhine Graben, eastern France): a key for future geothermal wells

BSGF - Earth Sciences Bulletin, 2019
Between 2012 and 2014, in Rittershoffen, in the Upper Rhine Graben, two geothermal boreholes (GRT-1 and GRT-2) reached the granitic basement at a depth of around 2150 m. The wells crossed about 1160 m of Cenozoic and 1050 m of Mesozoic.

Predicting the depositional environments and transportation mechanisms of sediments using granulometric parameters, bivariate and multivariate analyses [PDF]

, 2019
Grain size distribution and classes present in sedimentary rocks are responsive to the physical changes of the transporting media and the basin of deposition.

Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

Sedimentology, EarlyView.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

The hidden oases: unveiling trophic dynamics in Namib's fog plant ecosystem

Scientific Reports
The Namib Desert is a hyperarid coastal desert where fog is a major moisture source. We hypothesized that the fog-harvesting grass Stipagrostis sabulicola establishes an important ecological niche, termed the "Fog-Plant-Oases" (FPOs), and serves as the ...
