摘要
笔者据现有简要资料进行再次开发，用斯特雷凯森化学－标准矿物分类法，进一步明确蒲圻桐梓岭、青峰两斑岩体岩石类型－花岗间长斑岩，属同熔型岩体，结合岩体其他特征，并与鄂东、赣西北一些蕴藏大型铜、金矿床的小岩休类比，初步认为长江中下游成矿带可西延。
Based on re-processing of the present data, the author is convinced that the Tongziling and Qingfeng porphyry bodies belong to cyntectonic granodiorite- porphyry according to Stleikaso's chemical-standard minerals classification. Together with other caracteristics of these rock bodies, and comparing them with small rock bodies bearing large- scale coppergold deposits, the author assume the metallogenic zone at middle and lower Yangtze reaches extend toward west.
