Darwin atoll like development within the territory of CBGA regions
Convener: Geza Csaszar
A special type of reef has been recognized by Charles Darwin (1842). Its shape and form is determined by the volcanic - predominantly basaltic - bodies which usually occur along the subduction of the oceanic plate or on within-plate volcanoes in the tropical zone. Its first stage is the fringing reef, and the second one is the barrier reef. The typical Darwin atoll is usually the product of the warming up period of the Earth The shape of the Darwin atoll is determined by the shape of the volcano: circular, rectangular, irregular and elongated. This type of atoll has been recognized in the Mecsek Mountains in Hungary (Császár and Turnsek 1997) within the CBGA territory. It is high time to look around whether it is developed in other areas of the CBGA realm .
