Unformatted text preview: Oxygen and Carbonate Precipitation , Herringbone Calcite , and Archean Carbonate Precipitation and Oxygen ). To test this hypothesis, Ryoji is running calcite precipitation experiments under various conditions that may replicate Archean ocean conditions. Preliminary results show that Fe 2+ significantly reduces crystal nucleation rates, slows calcite precipitation, and strongly affects crystal morphology (see photo at right, AGU 1999 abstract and photos , and IGC 2000 abstract )....
