摘要: Microbial sediments of the biolaminated type, generated by matting behavior preferentially prokaryotic microbenthos, commonly carry isotopic signatures both primary microbial biomass and carbonate surrounding sediment matrix. This is true for present-day stromatolites as well their fossil counterparts, which can preserve these with a minor diagenetic overprint billions years. While composition organic (kerogenous) carbon fraction may reflect intrinsic fractionations producers several other parameters (productivity, temperature, salinity), δ13C δ18O labels, specifically sub-Recent laminated stromatolitic carbonates, have encoded wealth palaeohydrological palaeotemperature information makes them important stores palaeoclimatological data. Altogether, isotope record constitutes an exuberant archive biogeochemical palaeoenvironmental evolution that still awaits further evaluation.
