Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil
Journal of Petroleum Geology, EarlyView.ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Meteoritics &Planetary Science, EarlyView.Abstract We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...

Meteoritics &Planetary Science, EarlyView.Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field
Meteoritics &Planetary Science, EarlyView.Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

FROM SCANDINAVIA TO THE LEVANT: THE LATE BRONZE AGE METAL TRADE AND NURAGIC SARDINIA
Oxford Journal of Archaeology, EarlyView.Summary A growing body of evidence suggests that Nuragic Sardinia played a role, as yet poorly understood, in the metal trade between Scandinavia, Atlantic Europe, and the Mediterranean during the Bronze Age. Provenance studies based on lead isotope and chemical analyses of copper‐based – and to a minor extent lead – artefacts from both continental ...
