There is a vein (431 vein) in Hsianghualing district, Linwu County, Hunan Province, and it has been investigated and named “aplite” or “altered aplite” by many geologists and petrologists. On the basis of thorough study in the field work and in laboratory, and according to its occurrence, structure, texture, petrochemistry and mineral assemblages, the authors of this paper have an objection to this name and are of the opinion that it is a new type of ultrahypabyssal rock, and name it hsianghuagite.In this paper, the authors recommend briefly the characteristics of hsianghuagite, make a comparison between hsianghuagite and the relative rocks such as ougonite, topazite, etc., and discuss the origin of hsianghuagite.
