Abstract
SUMMARY Initial results of investigation of the diagenesis of calcareous algae by electron microprobe are: 1 A few conceptacles and other cavities in Recent algae specimens are partly to completely filled with younger carbonate. In contrast to the surrounding skeleton of about 10–20% mol MgCO3-calcite, these deposits are either very low (0–2%) or very high (15–50%) in MgCO3 content. 2 Highest magnesian values in Recent algae studied are thought to be in high-Mg calcites rather than in any other phase, with very few possible exceptions. 3 Calcian dolomite replacing fossil algae in cores from Eniwetok Atoll commonly has Ca-rich lenses resembling exsolution laminae.
