Summary

Changes attributable to weathering have been detected in Quaternary sediments overlying an important aquifer in the Vale of York. Solution of carbonates is quantitatively the most important effect of weathering. The amount of carbonate dissolved can be estimated from whole rock analyses. The length of time of weathering is known and an equivalent surface lowering rate for limestone can be calculated which is consistent with rates obtained by other workers.The volume of water required to give the observed compositional changes is calculated from porewater analyses. The time period is known and hence the rate of infiltration and the average recharge rate of the aquifer can be determined. The calculated rate of recharge is consistent with rates determined using other methods.
