[O03-P56] Filtering capability of fossil coral skeletons Porites sp. and Favia sp.

Keywords:fossil coral skeleton, filtering capability, Kikai Island, resource utilization

This study has focused on the filtration capacity of the fossil coral skeleton for resource utilization. Three experiments (water passing experiment, filtration experiments with chalk powder and black ink) were performed using fossil Porites sp. and fossil Favia sp. collected from Kikai Island, Kagoshima, Japan. Water passing experiment revealed that Porites skeleton passes distilled water. In the filtration experiments, Porites skeleton showed a filtration capacity, while, Favia skeleton did not show the capability. The chalk powder was filtered by Porites skeleton; however, the black ink was not filtered due to the particle size. This study suggests that fossil coral skeletons have the potential for effective resource utilization.
