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 sulfur isotopic composition of Anqing copper deposit is complex. Can not be explained by a single source of sulfur or changes in physico-chemical conditions. Based on the regional metallogenic geological background and the geological characteristics of the deposit, the paper studied six possible mechanisms (models) of sulfur migration from sulfur source geology to ore-forming hydrothermal fluids and determined the sulfur source of the deposit.
