Rock weathering has an important influence on biogeochemical cycling. It controls nutrient flux in the
biosphere and long term climate through CO2 drawdown. However, weathering does not only occur by chemical and physical factors. Microorganisms play a role in the weathering of rocks. This, however, is little understood and one major question is why weathering rates are so different in the laboratory compared to the field.
This work aimed to understand the influence of water-rock ratios on the rate of microbial weathering of basalt.
