| Outline of Final Research Achievements |
As part of development of teaching materials for learning diagenesis we tried to visualize the secular change of mineral composition and mineral texture of fossil shell, and to make a development the teaching materials for logic-based study on fostering the concept of time. We also studied supplementally and preliminarily cementation of beachrocks. Quantitative ratios of aragonite and calcite were divided into three groups. Mineral textures were divided into two types. The mineral composition and the mineral textures corresponded to each other. The correspondence relation between the mineral composition and mineral texture was connected to the occurrence of fossils in sedimentary rocks. Based on the mention above we found two patterns of the changing process of mineral composition and texture in fossil shell with the progress of diagenetic effect and showed a pattern diagram of the process.
