Petrology of the Eocene alkaline volcanism from the western Rio Grande Rise, South Atlantic Ocean

Frontiers in Earth Science
The origin and evolution of the Rio Grande Rise is deeply related to the opening of the South Atlantic Ocean. The geology of the plateau records the transition from divergent plate margins at the Mid-Atlantic Ridge to an intraplate tectonic setting ...

Biogeochemical sulfide mineralization in the volcanic-hosted Tongguan hydrothermal field, southern Mid-Atlantic Ridge

Frontiers in Marine Science
Biogeochemical mineralization is increasingly recognized as a significant factor in the formation of submarine hydrothermal sulfide deposits. While several mechanisms by which hydrothermal organisms may facilitate metal deposition have been documented in

cationCalc4EPMA: A MATLAB-based open-source tool for reproducible cation calculations from EPMA datasets

SoftwareX
Electron probe microanalysis (EPMA) provides precise chemical compositions of minerals, but transforming oxide weight percentages into cation-based formulas remains a critical and often irreproducible step in petrological workflows.
