Preservation of organic matter during salinity excursions

  title={Preservation of organic matter during salinity excursions},
  author={G. P. Klinkhammer and Claude E. Lambert},
Sediment in a core recovered from the western Mediterranean contains anomalously high concentrations of dissolved strontium, calcium, chloride and sulphate. These unusual results mirror the effects of early diagenesis in evaporitic basins, and a new model is proposed to explain anomalies in the accumulation of organic carbon and its isotopic composition. Such anomalies may result from increased but preferential preservation of organics brought about by changes in the microbial community during… CONTINUE READING
