摘要：

The model incorporates diffusion analogous bioturbation and bioirrigation of sediment and first-order dissolution and precipitation of manganese. Application of the model to data sets from the Laurentian Trough environment of the Gulf of St. Lawrence gives values of 50 000 yr-1 for the precipitation rate constant and 250 yr-1 for the dissolution rate constant. -from Authors
