Flow chart tracing the conversion of basalt to bicarbonate, which can react in the soil, increasing its pH, or leach into groundwater and be converted to calcium carbonate in the o

Figure 1. Two potential pathways of calcium and magnesium silicates from the basalt dust after they react with carbon dioxide and water in the soil atmosphere. Pathway 1 results in neutralization of the soil acidity, and pathway 2 results in CO₂ capture.
