  1. Burns, SJ; Baker, PA; Showers, WJ, The factors controlling the formation and chemistry of dolomite in organic-rich sediments: Miocene Drakes Bay formation, California, Sedimentology and Geochemistry of Dolostones (January, 1988), pp. 41-52
    (last updated on 2019/09/21)

    These siliceous mudstones contain many small dolomite nodules, probably formed without a precursor biogenic calcite supplying Ca or HCO3- for dolomitization. Dolomite formation preferentially took place in sediment layers slightly richer in organic C than the surrounding sediments. Illustrates changes in the isotopic composition of dissolved CO2 that occurred with depth. The isotopic analyses show that dolomite formation did not begin until the pore waters were free of dissolved sulfate. -from Authors
