摘　　要：通过对青城子东部各金矿地质特征的研究,以小佟家堡子、林家三道沟金矿床为例,总结了区内金矿床的成矿地质特征,即金矿体主要以层状-似层状分布于盖县岩组下部和大石桥岩组上部层位,富集于各岩性接触地带。提出了小佟家堡子、林家三道沟等金矿床经历两大成矿期次,属于沉积变质-岩浆热液改造型矿床。明确了以尖山子断裂及其所派生的低序次构造为定位空间、以硅化石墨化等蚀变为找矿标志的主要找矿方向。In this paper, through the study of the geological characteristics of the gold deposits in east of Qingchengzi orefield, with Linjia Sandaogou and Xiaotongjia Baozi gold deposits as examples, the writer summarizes the metallogenic geological characteristics of gold deposits in east of Qingchengzi Orefield, which was layered - bedded in the lower horizon of Gaixian country rock fabric and upper horizon of Dashiqiao rock fabric, enriched in the lithological contact zone. This paper also put forward two metallogenic stages of Linjia Sandaogou and Xiaotongjia Baozi gold deposits, what belongs to sedimentary metamorphic magmatic hydrothermal deposit, also identified the main exploratory direction that positioned the space with Jianshanzi fault zone and derivative low tectonic generation, take silicified and graphited altera- tion for prospecting marks.
