安徽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６种可能机理（模型），并确定了矿床的硫源。
The sulfur isotope composition of the Anqing copper deposit in Anhui is complex and can not be explained by a single sulfur source or changes in physicochemical conditions. Based on the regional metallogenetic geological background and the geological characteristics of the deposit, this paper studies six possible mechanisms (models) of the sulfur migration from the sulfur source geology to the ore-forming hydrothermal fluids and determines the sulfur source of the deposit.
