摘　　要：营里金矿床产于燕山晚期闪长玢岩与三叠系和尚沟组长石砂岩的外接触带蚀变矿化破碎带中,褐铁矿化强烈是本区寻找金矿的重要找矿标志。金矿体赋存在三叠系黄褐、灰紫色长石砂岩中是我省金矿床类型中较为少见的一种类型。文章论述了金矿床所处的区域地质背景、矿区和矿床地质特征以及矿体赋存的空间方式,初步分析了矿床的成矿条件和控制因素。此外提出了一些尚需进一步研究的问题,希望能引起关注与探讨。Yingli gold deposit is located in the altered mineralized fracture zone of the outer contacting belt between the later Yanshanian diorite porphyry and Triassic Heshanggou group feldspar sandstone. Limonitization is the ore finding sign in the district. Gold ore bodies are hosted in gray - purple feldspar sandstone. It is rare type gold deposit in Hebei province. Regional geological background, geological features and spatial mode of ore bodies are discussed. Mineralization condition and ore - controlling factors are analyzed. Some matters for the future research are also put forward.
