Frontiers | The Dissolution of Olivine Added to Soil at 4°C: Implications for Enhanced Weathering in Cold Regions
Crushed olivine was added to a core to mimic enhanced weathering, and water was continually dripped through for ~6 months. Our experiments were conducted at 4°C, and are compared to previously run identical experiments at 19°C. Olivine dissolution rates in both experiments start out similar, likely due to fines and sharp crystal corners. However, after >100 days of reaction, the dissolution rate at 4°C was two orders of magnitude lower than at 19°C. The accumulation of hea...
