A study of Cheung Chau Island has revealed a close adjustment between the form of the island and the geological structure. The island is made up of dominant granite cut by granite-porphyry and dolerite dykes, which are affected by later faulting. A theory of progressive emergence is put forward for the denudation chronology of the area and the various forms related to the former submergence have been mapped. The relation of coastal and inland forms to structure is considered, and the evolution of the coast is outlined.
