Relation entre les teneurs en soufre des biominéraux calcaires et leurs caractéristiques minéralogiques

Abstract

Sulfur concentration measurements in calcareous invertebrate hard-parts covering a wide range of taxa are compared, using relevant statistical tools, to mineralogical and microstructural features of skeletons. In parallel with recent data concerning sulfur characterization in mineralizing matrices, this allows the current concepts regarding early stages and further development of calcareous biominerals to be discussed.
