Abstract

It was happy for me to participate in the Coral Annual Banding Workshop held in Tsukuba on Oct. 20, 2003, as a commentator. In the workshop, I was impressed greatly by the presentation of the fresh and exciting stories. I have made the chemical and geochemical studies on carbonates for these fifty years. I have published many reports on the following subjects: (a) geochemical study on calcareous deposits in 17 hot springs of Japan, (b) factors controlling the polymorphic crystallization of CaCO<sub>3</sub>, especially the influence of chemical species dissolved in parent solution, (c) partition of minor chemical species between CaCO3 and solution: divalent cations (Mg<sup>2+</sup>, Cu<sup>2+</sup>, Zn<sup>2+</sup>, Cd<sup>2+</sup>, Sr<sup>2+</sup>, Ba<sup>2+</sup>, UO<sub>2</sub><sup>2+</sup>), alkaline ions (Li<sup>+</sup>, Na<sup>+</sup>, K<sup>+</sup>, Rb<sup>+</sup>, Cs<sup>+</sup>), inorganic anions (halogen ions, SO<sub>4</sub><sup>2-</sup>, phosphate ions, borate ions), H<sub>4</sub>SiO<sub>4</sub> and organic materials, (d) geochemical study on marine biogenic carbonates, (e) synthesis of (Ca, Mg) CO<sub>3</sub> under normal temperature and pressure condition, (f) transformation of marine biogenic carbonates, (g) origin and evolution of seawater using those of CO<sub>2</sub> on the earth, and (h) global warming. At the workshop, I hoped heartily and strongly for active geochemists on coral to promote the basic studies on the strange but interest characters of CaCO<sub>3</sub> and also to present the exact data on global carbon cycle. My hope and expectation are shown in this paper with the chemical and geochemical results obtained by myself.
