Abstract

The objective of this study was to develop a protocol to test the reactivity of glauconite, a Fe/Mg bearing aluminosilicate mineral, in carbon storage. A selected glauconite-rich sample from the Cambrian Riley Formation of Central Texas was used containing glauconite 38 wt%, quartz 58 wt%, and calcite 4 wt%. Ten experiments were conducted using two techniques where total pressure was: 1) controlled by delivering CO2 to a high-pressure apparatus; 2) kept at saturated vapor level in autoclaves. The treated glauconite samples were analyzed with Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (SEM), and X-ray Diffraction techniques (XRD). Although the reaction between glauconite and CO2 was not visible, calcite crystallized in solution when its pH exceeded the value of 6.88. The research provides a foundation to develop further investigations of rock reactions under CO2 saturated conditions.
