| Abstract: | High-magnesium calcite overgrowths were precipitated on Iceland spar calcite crystals buried in Bahamian sediments. Their composition was within the range of carbonate cements in this area. The precipitation rate of the overgrowths was slower and the magnesium content higher than predicted from laboratory experiments, possibly due to adsorption of organic compounds. |
