Thirteen closely spaced core holes were drilled across a modern fringing reef at Galeta Point, Panama, along two transect lines which, when combined, extend from inshore mangroves to the outer reef slope. Cores indicate that the reef is at least 14 m thick and directly overlies the calcareous argillaceous silt-stone of the middle Miocene Gatun Formation. Cores contain six distinct sedimentologic units: reef Acropora palmata, fore-reef coral heads, fore-reef talus, fore-reef pavement, reef-flat rubble, and back-reef sediments facies. Eighteen radiocarbon dates of coral samples from cores permitted detailed reconstruction of the stages of development of Galeta reef. Refs.
