Dataset for: Continental chemical weathering traced by lithium, strontium, and magnesium isotopes — the case of the Salitre Formation, Irecê Basin, Brazil

This dataset contains geochemical and isotopic data from Neoproterozoic carbonate rocks of the Salitre Formation (Irecê Basin, São Francisco Craton, Brazil). The data were generated to evaluate continental chemical weathering using a multi-isotopic approach, focusing on lithium (δ⁷Li), strontium (⁸⁷Sr/⁸⁶Sr), and magnesium (δ²⁶Mg) isotopes. Major and trace element concentrations and key geochemical ratios are also included to assess the degree of diagenetic alteration and sample preservation. This dataset supports the article submitted to Geochemistry, Geophysics, Geosystems (G3) entitled: "Continental chemical weathering traced by lithium, strontium, and magnesium isotopes: The case of the Salitre Formation, Irecê Basin, Brazil"
