摘要
安庆铜矿床的硫同位素组成复杂．不能用单一硫源或物理化学条件的变化来解释。本文依据区域成矿地质背景及矿床地质特征，研究了硫从硫源地质体转移到成矿热液中的六种可能机理（模型），并确定了矿床的硫源。
The Anqing copper tieposit has a complicated suifur isotope compositions t which can not be explained by the mechanisms of variations of sulfur isotope composition of the sulfur sources or the physicochemical conditions. Based on the regional metallogenic geological setting and the geological characteristics of the mineralization,this paper has proposed six possible mudels for sulfur moving from the sources into the ore-forming hydrothermal solutions of which only the Ⅲ-model explains well for the splfur isotope composition and defined the sulfur origins for the Anqing copper deposit.
