- Abstract
Studies of modem coral reefs have shown that Holocene reef growth is relatively thin, and that in many instances it has developed on an older limestone surface1-4. This surface is commonly associated with leaching and pedogenic processes, indicative of subaerial exposure, and has been termed the solution unconformity5. Investigations into reef growth history have interpreted the pre-Holocene substrate as an older reef surface2-4,6-8 that may or may hot have undergone karst erosion during periods of lower sea level6,9. Uranium-series dating of corals directly below the uppermost solution unconformity at Eniwetok10 and Mururoa11 has shown that previous reef growth, before the Holocene, occurred ∼120 kyr ago. We present here 230Th/234U dates that confirm a last interglacial age for reefal limestones directly beneath the uppermost solution unconformity in the southern Great Barrier Reef.
