Diagenesis in carbonates
WebCarbon and oxygen isotope ratios in diagenetic carbonates from marine sediments. The isotopic composition of some sixty samples of penecontemporaneous diagenetic carbonates from marine horizons shows that they are strikingly different from normal marine limestones. The variation of C 13 ratio is 5·6 per cent, the lightest carbonate … WebCarbonate minerals in modern marine sediments can readily be divided into those found in shoal-to-shallow and deep-water environments. The factors controlling the sources, mineralogy, and diagenesis of carbonates in these environments are very different. Within the shoal-to-shallow water environment, the sources and diagenesis of carbonates …
