摘　　要：盖县猫岭金矿床以毒砂和磁黄铁矿为主.毒砂可划分为大颗粒毒砂、细脉状及毒砂石英脉中的毒砂和细粒浸染状毒砂三种性状.毒砂与金矿化密切相关.化学分析结果表明,矿区毒砂为“硫”毒砂,形成于中低温条件、中深部位.毒砂中δ^(34)S值同辽河群的δ^(34)S相一致,表明毒砂中的硫来源于辽河群.The principal sulphides in Maoling gold deposit are arsenopyritc and pyrrhotitc.Three kinds of state of arscnopyrite are developed at the deposit, i. e. corse-grained arsenopyritc, veinlet arsenopyrite and arsenopyrite-bearing quartz vein, and fine-grained disseminated arsenopyrite.Gold mineralization is closely related to arscnopyrite .The results of chemical analysis show that arsenopyrite in the deposit belongs to 'sulfur* arsenopyrite which is formed at low-medium temperature(250-350° ), and in shallow-medium depth. The δ34S value in arsenopyrite is consistent to that in Liaohe Group, which shows that the sulfur source of arsenopyrite is derived from Liaohe Group. Typomorphic peculiarities of arsenopyrite exhibit the origin of Maoling gold deposit.
