香花岭岩的研究

本文在野外与室内研究工作的基础上,对湖南临武香花岭地区原名“细晶岩”或“蚀变细晶岩“的“431岩脉”的岩石名称提出了异议,并对其进行了地质产状、岩石结构构造、岩石化学及矿物组合特征的研究.除简要介绍了香花岭岩的各种重要特征外,还将与之近似的岩石,如翁贡岩、黄英岩等作了分析对比,最后,并对其成因问题作了初步探讨。     

HSIANGHUAGITE——A NEW TYPE OF MAGMATIC ROCK

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.
