Subsequently, the granites were buried in sediments and then intruded by NNW-SSE oriented basic dykes in the Permian. In the Mesozoic the rocks were subject to significant weathering resulting in the formation an irregular grand-scale relief called the Sub-Mesozoic hilly peneplain. At a smaller scale the weathering is thought to have produced numerous small rock basins now seen near the coast.
