Whole-rock major and trace element concentrations of the Oumjrane Gabbronorite, Eastern Anti-Atlas, Morocco

This dataset provides whole-rock geochemical data from the Oumjrane gabbronorite intrusion, located in the eastern Anti-Atlas (Morocco), within the Northwest African Variscan belt. The studied samples were collected from a fully cored borehole intersecting a mafic intrusion emplaced within Paleozoic sedimentary successions of the Tafilalet–Maider basins, during three field campaigns conducted between 2021 and 2023.
