Investigations of gallstone have been restricted to its organic composition. Regarding its inorganic constituents, except for calcium carbonate, only few works have been reported. In particular, the existing form of minor elements in it has rarely been tackled. After a detailed mineralogic study on several gallstone samples from Guiyang and Choniang, Guizhou Province, some new findings
