Detrital zircon and rutile U–Pb geochronology, rutile trace-element geochemistry, and paleocurrent data from the Eleutério and Castro basins, southern Brazil

This dataset contains the complete analytical results supporting the doctoral thesis "Proveniência sedimentar das bacias de Eleutério e Castro com base em zircão e rutilo detrítico" (UNESP, 2026), which investigates the provenance and tectono-sedimentary evolution of the Eleutério and Castro basins, southeastern and southern Brazil. Data were acquired by LA-ICP-MS at UNESP Rio Claro, following the analytical protocols described in the thesis. Isotopic ratios and ages are reported with 2σ uncertainties. The dataset comprises seven tables: Paleocurrent measurements, Eleutério Basin Detrital zircon U–Pb data, Eleutério Basin Detrital rutile trace-element data, Eleutério Basin Detrital rutile U–Pb data, Eleutério Basin Detrital rutile trace-element data, Castro Basin Detrital zircon U–Pb data, Castro Basin Detrital rutile U–Pb data, Castro Basin
