Study on the Relationship between Transparency and Mineral Compositions of Shoushan Stone

摘要

The Shoushan Stone is one of the famous craft carving stones in China and transparency is one of the key indicators to evaluate the value of Shoushan Stone. The better the transparency is, the higher the value is. In this study, the mineral compositions and morphologies were investigated by XRD and SEM, respectively. Combining with the characterization of Shoushan Stone samples, the relationships between mineral composition, morphology and transparency were studied. The results show that the transparency of Shoushan Stone is determined by the mineral categories and microstructures. The sample with high transparency is fewer mineral composition numbers, similar mineral compositions and bigger crystal particles.
