| 摘 要： | 通过对鸡叫沟金矿床的成矿地质背景、矿床地质特征、找矿标志及控矿因素等到诸方面分析，指出鸡叫沟金矿床成矿物质主要来源于岩浆岩，矿体主要分布于黑云母花岗闪长岩、超基性角闪石岩岩体与奥陶纪地层的内外接触带上，且受多级断裂裂隙系统控制。矿石类型为石英脉型、蚀变岩型、石英脉＋蚀变岩型，矿化类型主要有黄铁矿化、黄铜矿化、磁黄铁矿化、方铅矿化、毒砂化等。深部岩浆房为矿床形成提供了热动力，矿床成因类型为与岩浆岩有关的低温热液型金矿床，在此基础上，总结归纳了该矿床的成矿模式与综合找矿标志。

| Abstract: | Based on analysis of ore-forming geological setting,geological features,ore-prospecting indicators and ore-control factors of the Jijiaogou gold deposit,this paper argued that ore-forming material of the gold deposit was sourced from igneous rocks and that ore body mainly distributes in the inner and outer contact zones of biotite granodiorite and ultrabasic hornblendite intrusions with Ordovician strata and is controlled by multi-level fault fissure system.Ore types are mostly quartz veins,altered rocks,qu... |
