摘　　要：文章详细研究庚村和黄双岭萤石矿的同位素分析结果，得出如下主要结论：成矿溶液来源于当地中生代大气降水；Ｓｒ，Ｂａ，Ｃａ来源于强蚀变的围岩；矿液中存在有ＨＦ和ＳｉＦ４。成矿过程氢、硫同位素出现交换动力学效应；庚村和黄双岭萤石矿的成矿年龄分别接近８４Ｍａ和１０７Ｍａ。This paper are studied in dedail the result of isotope analyses in Gengcun and Huangshuangling fluorite ore,and the main conclusions are as follows:(1) The ore forming fluids was derived from Mesozoic local meteoric water;(2) Sr,Ba,Ca elements in the ore bearing fluids was derived from intensely altered country rocks;(3) It is suggests that the presence of HF and SiF 4 in ore forming fluids and presenec of hydrogen(Gengcun and Huangshuangling) and sulfur(Gengcun) isotopic effects during metallogenetic processes in Gengcun and Huangshuangling fluorite ore;(4) The time of mineralization ranges 84 Ma￣107 Ma of Gengcun and Huangshuangling fluorite ore.
