PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.993451 (dataset in review)
Abstract:
This dataset provides mineralogical and geochemical data from the Oumjrane gabbronorite intrusion, located in the eastern Anti-Atlas (Morocco), within the Northwest African Variscan belt. Samples were collected from a fully cored borehole intersecting a mafic intrusion emplaced within Paleozoic sedimentary successions of the Tafilalet–Maider basins, during field campaigns conducted between 2021 and 2023. Mineral chemistry data were obtained using JEOL Electron Probe JXA-8230 and a LA-ICPMS system, 213-nm Nd-YAG Merchantek laser connected to a Thermo Finnigan Element 2 sector-field mass spectrometer. The dataset includes major and trace element concentrations, as well as derived parameters (e.g., Mg#), and serves as input for thermobarometric, hygrometric, and oxybarometric calculations. All data are provided in tabulated format with complete metadata, ensuring reproducibility.
The olivine dataset specifically includes major and trace element compositions determined by EPMA and LA-ICP-MS. Reported elements include Fe, Mg, Ca, Mn, Ni, Ti, Zn, and Li, along with calculated Mg#. These data are suitable for thermometric and oxybarometric applications and support the investigation of magmatic differentiation processes.
