A multidisciplinary study on the location of Roman sites in the southern sub‐plateau of the Iberian Peninsula

Archaeometry, EarlyView.
Abstract Architectural and engineering elements of the Roman civilization constitute an important cultural heritage. Nevertheless, not all ancient Roman cities and the roads connecting them have been found, mainly because classical geographical sources show a significant lack of precision.

Geochemical Signatures of Potassic to Sodic Adang Volcanics, Western Sulawesi: Implications for Their Tectonic Setting and Origin [PDF]

, 2016
DOI:10.17014/ijog.3.3.195-214The Adang Volcanics represent a series of (ultra) potassic to sodic lavas and tuffaceous rocks of predominantly trachytic composition, which forms the part of a sequence of Late Cenozoic high-K volcanic and associated ...

Coupling Phase Equilibrium Modelling and Apatite‐in‐Garnet Elastic Barometry to Unravel the P–T Path of the Micaschist Unit From the Zicavo Metamorphic Complex (Corsica, France)

Journal of Metamorphic Geology, EarlyView.
ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

Oued Chebeika 002: A new CI1 meteorite linked to outer solar system bodies

Meteoritics &Planetary Science, EarlyView.
Abstract CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ryugu and Bennu asteroids returned by the JAXA Hayabusa2 and NASA's OSIRIS‐REx missions.

A feasibility assessment of micromill sampling for Rb‐Sr and Sm‐Nd geochronology of shergottites

Meteoritics &Planetary Science, EarlyView.
Abstract Accurate dating of Martian meteorites is crucial for understanding key events in the planet's evolution. However, not all Martian meteorites are amenable to dating techniques currently in use for these rocks. The priority of sample preservation precludes mineral separation methods for low‐volume specimens, whereas the less destructive in situ ...

Bacterial dissolution of fluorapatite as a possible source of elevated dissolved phosphate in the environment [PDF]

, 2011
In order to understand the contribution of geogenic phosphorus to lake eutrophication, we have investigated the rate and extent of fluorapatite dissolution in the presence of two common soil bacteria (Pantoea agglomerans and Bacillus megaterium) at T ...

Biogeochemical characterization of micritized carbonate grains in the shallow‐marine Al‐Kharrar Lagoon (Red Sea, Saudi Arabia)

Sedimentology, EarlyView.
ABSTRACT Micritization of marine carbonate grains is an early diagenetic process involving the alteration of the original carbonate fabric and the formation of cryptocrystalline textures through cycles of dissolution and reprecipitation. Microorganisms play a significant role in this process, actively contributing to the formation of constructive and ...

The fate of William Whewell’s four palætiological domains : a comparative study [PDF]

, 2019
In 1847, the British polymath William Whewell pointed out that the sciences for which he, in 1837, had coined the term “palætiological” have much in common and that they may reflect light upon each other by being treated together.

Influence of Fluids and Geological Setting on Source Parameters of the 2010–2014 Pollino (Italy) Seismic Swarm

Terra Nova, EarlyView.
ABSTRACT We analyse variations in Brune stress drop (Δσ), apparent stress (τa) and Savage–Wood radiation efficiency (ηsw = τa/Δσ) during the 2010–2014 Pollino seismic swarm (Southern Apennines, Italy). This prolonged sequence included multiple swarms, with a Mw 5.2 event in October 2012, preceded by a Mw 4.3 event in May 2012, followed by aseismic slip.

Semantic linking of complex properties, monitoring processes and facilities in web-based representations of the environment [PDF]

, 2015
Where a virtual representation of the Earth must contain data values observed within the physical Earth system, data models are required that allow the integration of data across the silos of various Earth and environmental sciences domains.
