Fig. 3.25.— Island of Makatea in the SW Pacific is an uplifted Neogene atoll with some Holocene-Pleistocene reefs attached on the
sides. The saucer-shaped topography of the island is largely due to karst processes. However, terrestrial dissolution is selective and
closely follows the facies pattern of the original atoll – the present topography was not cut out from a homogenous limestone formation.
After Montaggioni et al. (1985), modified.
