| 摘 要： | 本文收集整理了桐柏一大别地区与中温热液金矿床有关的氢、氧、硫、铅同位素组成数据.分析整理结果表明,成矿流体和成矿元素及硫可能来自不同的源区.流体主要为大气降水,成矿元素和硫主要来自流体下渗及回返过程中流经的各类岩石.成矿流体的这种性质对于造山带内带及两侧金矿化的产出规模具有相当程度的影响.

| Abstract: | H. O, S, Pb isotopic date of the mesothermal Au deposits in Tongbai -Dabie area were collected and sorted out. Analysis of the results showed that there were different sources about fluids, sulfur and ore -forming elements in metallogenic fluids. The fluids mainly belong to precipitate waters, and sulfur and ore -forming elements came from some types of rocks that the fluids went through when the fluids permeated down and returned up in the continental crust. The Au minerallization scales in this area obviously were influfluenced by the characters of the metallogenic fluids. |
