| Outline of Final Research Achievements |
We succeeded in establishing an international collaboration team that enable us to obtain necessary samples to study. Calcium carbonate dissolved in rain water plays an important role in controlling the environment of West Asia. This viewpoint provides answers to questions thrown through archaeological studies. (1) Rain water rich in Ca-HCO3 can precipitate CaCO3 and form a hard crust near the surface of the sediment column. This mechanism has direct influence on salinization. (2) Alkaline rain water does not dissolve carbonates. Floodplain sediments and tablet clay in Mesopotamia contain calcareous tests of coccoliths derived from limestones in Zagros. (3) As a result, Mesopotamian clay and its products (clay tablet, adobe, etc.) contain a large portion of carbonates. The carbonates are originated from both reworked grains and CaCO3 precipitated from the ground water. Such precipitation may have played an important role in hardening clay products.
