A geometrical model of diagenesis using percolation theory

Karmakar, R.; Manna, S.S.; Dutta, T. - In: Physica A: Statistical Mechanics and its Applications 318 (2003) 1, pp. 113-120

We study the restructuring process of diagenesis in sedimentary rocks using a geometrical model of percolation theory. The competing processes of cementation and dissolution of diagenesis are modelled by growth of vacant sites and culling of occupied sites in a percolation model depending on a...
