Changhua Tianhuang Chicken-Blood Stone, a new variety of Tianhuang Stone, is divided by some people into two categories by its appearance, namely “Dong Di" Tianhuang Chicken-Blood Stone and “Gang Di" Tianhuang Chicken-Blood Stone. Based on analytical means such as EMPA, XRD, IR and chemical analysis, the authors studied Changhua Tianhuang Chicken-Blood Stone from Yuyanshan in Fujian Province. The results show that “Dong Di" Tianhuang Chicken-Blood Stone is mainly composed of dickite with a small amount of talc, while “Gang Di" Tianhuang Chicken-Blood Stone is mainly comprised of alunite with small amounts of dickite, quartz albite and talc. According to the general concept of Tianhuang, the authors believe that the “Dong Di" Tianhuang Chicken-Blood Stone can be categorized as “Tianhuang Chicken-Blood Stone", whereas the “Gang Di" Tianhuang Chicken-Blood Stone may be only defined as “Changhua Chicken-Blood Stone" and cannot be called Tianhuang because of its mineralogical characteristics.
