| Abstract: | The outline of the Pleistocene coastal geomorphology in the Tuléar area (Madagascar) can be redrawn from the analysis of the setting and characteristics of present-day coral reefs. Initial outer reef tracts, which grew in Tatsimian times (according to Battistini's terminology), followed in their development the river pattern, since they settled upon the divides between valleys instead of growing uniformly on the outer shelf. These primary reef chains coalesced subsequently. Inner reefs and coral banks also followed, although not so closely, the river pattern. |
