This study investigates the potential of basalts from the Serra Geral Group for geological CO2 storage, focusing on the geochemical behavior of the rocks under reservoir-like conditions at a depth of 900 m. Massive and brecciated basalt samples were characterized in terms of porosity, permeability, and petrography. Closed-system reactor experiments will be conducted at 50 bar and 40 °C for 24 weeks to simulate fluid-rock interactions. Post-experimental analyses will include SEM-EDS, X-ray microtomography, petrographic descriptions to assess mineralogical alterations, and for the fluid; analysis of pH, electrical conductivity, total alkalinity, and chemical composition (ICP-MS and IC). The goal is to evaluate basalt reactivity and its potential for carbonate mineralization and long-term CO2 sequestration.
