Short summary
The olivine carbonation reaction is volume increasing and could prevent further reaction by clogging the fluid pathways. This contradicts the observed fully carbonated outcrops in nature, but the mechanism behind this self-sustainability is poorly understood. Our study reveals that the stretching-induced fracturing and the dissolution channelization are mechanisms that could contribute to the sustainability of carbonation reactions. This study provides new insights on the olivine carbonation.
