Short summary
We used a numerical model to assess the effect of grain size and rock composition on chemical weathering and grain detachment. Our simulations showed that grain detachment represents more than a third of the overall weathering rate. We also found that as grain size increases, the weathering rate initially decreases; however, beyond a critical size, the rate became approximately constant. Our results could help predict the sometimes complex relationship between rock type and weathering rate.
