Benthic cyanobacteria research in high mountain reservoirs remains limited, mainly due to their complexity and knowledge gaps that persist in relation to their ecology in tropical regions. This study aimed to explore the...

In coastal areas, microplastics (MPs) can deposit in sediment, allowing it to be ingested by benthic organisms, like mussels, thus creating a possible transfer to humans. The aim of this study is to evaluate MPs pollutio...

Abstract A total of sixty surface sediment samples were systematically obtained from ten distinct locations along the Sudanese coastline of the Red Sea during the summer season (June 2016) and the winter season (February...

The Pampeano aquifer formed by loess-like sediments provides water to cities and for agricultural uses in the Pampean plain, which is the most productive area in Argentina. Studies on the mechanisms through which this gr...

"The fissility is the ability of some rocks to split along relatively smooth surfaces parallel to the bedding. This property observed mostly in fine-grained rocks is particularly expressed in outcrops, where rocks are su...

Neste estudo foram analisados pH, Eh, condutividade elétrica, cloreto, sílica, fosfato, K, Na, Ca, Mg, Fe, F, Zn, Ni, Co, Mn, Pb, Cu, Cr, Li e Cd nas águas de drenagens de pequeno porte no nordeste do Amazonas. As ág...

The water quality characteristics of shale oil produced water are complex and highly unstable, which poses difficulties for its treatment, storage, and resource utilization. This study focused on shale oil produced water...

Predictive modeling of natural sediment-laden flows requires rheometric protocols that are both reproducible and time-aware of sediment dynamics. This study establishes a standard measurement protocol for homogeneous sed...

Contamination with anthropogenic debris, such as plastic and paint particles, has been widely investigated in the global marine environment. However, there is a lack of information regarding their presence in marine prot...

Abstract Lead (Pb) isotopes are powerful tools for tracing dust provenance and reconstructing paleoclimate. However, variations in Pb isotopic compositions among different grain‐size fractions in sediments complicate t...

In this paper we illustrate the stratigraphy, geochronology, and geochemistry (major, minor, trace elements and Sr-isotopes) of a Holocene tephra layer found within coastal sedimentary deposits north of Caleta Olivia (Sa...

We describe nine angiosperm fossil woods from sediments of the Cardiel Formation (Upper Cretaceous) near the Cardiel Lake, Santa Cruz Province, Argentinian Patagonia. On the basis of the characteristics of the anatomy, t...

This study reports LA-ICP-MS U–Pb ages and Lu–Hf isotope data of detrital zircons from sedimentary rocks of the Nanduan Formation in the Changning–Menglian tectonic belt. The U–Pb age spectra display three domina...

Intestinal microbiota of aquatic animals is closely associated with the environment, influencing their health, immune defense, and environmental adaptability. To understand the relationships among the Manila clam (Rudita...

his study focused on the geochemical and isotopic features of thermal fluids discharged from five zones located in the high altitude Puna plateau (Jujuy Province between S 22°20′–23°20′ and W 66°–67°), i.e. G...

In this study, the chemical and isotopic composition of thermo-mineral springs from the Rosario de la Frontera hydrothermal system was used to construct a conceptual model describing the source regions the thermal fluids...

In mid-2023, a preprint was uploaded by some of the team working at the Rising Star Cave System in South Africa on new finds regarding the hominin Homo naledi. The authors reported what they claim is evidence for deliber...

Preservation of arthropod cuticles is of paramount importance for taphonomic interpretations in which the fossil record of the chitin-protein complex is considered a key molecular signature of the group studied. In this ...

Background: Forests are used for multiple purposes worldwide, which often include timber harvest, firewood extraction and livestock raising. An excessive pressure on multipurpose systems may decrease soil cover, promotin...

Several archaeological black earth (ABE) sites occur in the Amazon region. They contain fragments of ceramic artifacts, which are very important for the archaeological purpose. In order to improve the archaeological stud...

Water quality in the Paso Piedras Reservoir has deteriorated, primarily due to periodic blue-green algal blooms, making it temporarily unfit for human consumption. This phenomenon results from the eutrophication of water...

The present chapter deals with provenance analysis of a carbonate-siliciclastic Ordovician sedimentary unit of the San Rafael block, named the Ponón Trehué Formation (Darriwilian to Sandbian). This is the only sequence...

Summary Trace-element data for mid-ocean ridge basalts (MORBs) and ocean island basalts (OIB) are used to formulate chemical systematics for oceanic basalts. The data suggest that the order of trace-element incompatibili...
