Research Abstract |
Shell of mollusks is composed mainly of the calcite and aragonite, there are cases that calcite and aragonite are mixed into the shell. In this study, abalone shells, which have a mixture structure of calcite and aragonite, are used as a material. The shell microstructures of the outer shell layer are examined by using Raman spectroscopy and oxygen stable isotope analysis. As a result, I found that calcite and aragonite are distributed in the outer shell layer as a thin layer separately, and formed at the same time.
