Structural and Textural of Marine Mollusc Shell

Abstract:

The Anadaragranosa and Pernaviridis shell sample were prepared in powder and plate form has been studied. The crystal structure of the shells was studied by x-ray diffraction (XRD). The identification and quantitative analysis were performed by the XRD patterns and the Rietveld method. It found that the crystal structure of Anadaragranosa shells is a pure aragonite phase, and the Pernaviridis shells is a mixture phase of aragonite and calcite. Also we used the scanning electron microscope (SEM) to study the Morphology of the Anadaragranosa and Pernaviridis shell sample. The results on SEM micrographs agree well with those of XRD. The results from SEM can be described the textural information and used to determine of the mollusc shell. In addition, the metals in the shells were determined by ESR spectroscopy. The metals in all samples reveals that Mn were found in all mussel shells, and then the ESR spectrum agree well with those of XRD and SEM result, then it can be used to indentification of structural of mollusc shell.
