Abstract
The early signs of diagenesis in aragonitic coral skeletons have been studied by the analysis of soluble organic matrices associated with sk eletal structures of Acropora from recent to Pleistocene reefs of Muru roa (French Polynesia). Transformations are evidenced in the fossil, t hrough the quantitative decrease of the organic matrix and changes in the composition of both proteic and glucidic components. Primary featu res still preserved in acidic proteins (molecular weight and charges) probably take part in maintaining mineralogical characteristics.
