Descriptions

This dataset comprises new chemical, isotopic and geochronological analyses for 3 samples from the Cenomanian Serra do Cuó olivine basalts from northeast Brazil. Whole rock major, trace element and Sr-Nd-Pb isotope compositions as well as mineral oxide compositions for pyroxenes, plagioclase, olivine, and Fe-Ti oxides. New analyses on 3 samples are presented in the bulk and in-situ data templates developed by EarthChem. A compilation of all new analyses and previous whole-rock data from Sial (1978) are also provided. Analyses were carried out at the Geoanalítica Core Facility, Isotope Geology Research Center and Geochronological Research Center (CPGeo) at the Instituto de Geociências, University of São Paulo, Brazil. This dataset is supplementary to: Macêdo Filho, A. A., Oliveira, A. L., Klöcking, M., Janasi, V. A., Archanjo, C. J., & Lino, L. M. (2025). Petrology of Cenomanian basalts on the Brazilian equatorial margin: Implications for the tectonomagmatic evolution of the drift phase. Geochemistry, 126248. https://doi.org/10.1016/j.chemer.2025.126248. The data publication includes the following Excel Tables: (1) 2025-002_MacedoFilho_BulkSample_Analyses (DIGIS/EarthChem Template, EarthChem Team, 2022a): Whole rock major, trace element and Sr-Nd-Pb isotope compositions and 40Ar/39Ar age; with additional information on sample collection and analytical methods. (2) 2025-002_MacedoFilho_InSitu_Analyses (DIGIS /EarthChem Template, EarthChem Team, 2022b): Mineral oxide compositions for pyroxene, plagioclase, olivine, and Fe-Ti oxides; with additional information on sample collection and analytical methods. (3) 2025-002_MacedoFilho_suppl-compiled: supplementary data tables from Macêdo Filho et al. (2025). Excel file with the six spreadsheets: Table A1. whole-rock chemistry; Table A2. Feldspar chemistry; Table A3. Pyroxene chemistry; Table A4. Olivine chemistry; Table A5. Titanomagnetite chemistry; Table A6. Ar-Ar Geochronology. Table A1 compiles analyses from Sial (1978) as well as new data. Reference: Sial, A. N. (1978). Major and trace chemistry of the Tertiary basaltic suite of Rio Grande do Norte and Paraíba, northeast Brazil. Jornal de Mineralogia, 7, 119-128.
The DIGIS geochemical data repository is a research data repository in the Earth Sciences domain with a specific focus on geochemical data. The repository archives, publishes and makes accessible user-contributed, peer-reviewed research data in standardised form (EarthChem Team, 2022, https://doi.org/10.26022/IEDA/112263) that fall within the scope of the GEOROC database (https://georoc.eu). All submissions of new data will be considered for inclusion in the GEOROC database. It is hosted at GFZ Data Services through a collaboration between the Digital Geochemical Data Infrastructure (DIGIS) for GEOROC 2.0 (https://digis.geo.uni-goettingen.de) and the GFZ German Research Centre for Geosciences.
