Busuanga Island is known as a recreational diving location due to World War II Japanese wrecks that were sunk by American navy bombings in Coron Bay, a natural anchorage near the town center of Coron, on September 24, 1944.[1]
Part of the North Palawan Block, Busuanga Island consists mainly of the Liminangcong Formation, a PermiantoLate Jurassic chert. This chert forms the distinguishing mountain ranges, with the Middle-Late Jurassic Guinlo Formation clastics forming the valleys on Busuanga.[2] Busuanga was known for its tabular manganese deposits found within the chert sequence, 1 meter (3 ft 3 in) thick and extending laterally up to 200 meters (660 ft). Braunite is the common manganese mineral type found in the ore.[3][4][5]
