| Research Abstract |
Hydrous calcium carbonates such as amorphous calcium carbonate and monohydrocalcite are important for the biominerals and environmental proxies. On the other hand, these minerals are metastable phase and quickly transform to the stable anhydrous calcium carbonates. In present study, the formation conditions and stabilities of these metastable minerals were examined by means of the systematic synthesis experiments and in-situ infrared spectroscopic observations. This study clarify quantitatively the effect of dissolved magnesium on the formation and stability of these minerals.
