通过开展详细的室内外研究,对吉林蛟河爱林金矿床成矿地质特征及矿床成因进行了探讨。野外调查发现,矿体呈脉状产于范家屯组粉砂质板岩中的断裂蚀变带中,受NE向断裂控制。流体包裹体测试结果表明:爱林金矿床成矿期流体均一温度为240~400 ℃,成矿深度为0.64~1.60 km。氢氧同位素测试结果显示,成矿流体δ 18O变化范围为5.40‰~6.86‰,δD变化范围为-103.1‰~-100.0‰,表明成矿流体具有岩浆水与古大气降水混合的特征。综合区域地质特征、矿体产出状态和实验分析,认为该矿床属于受断裂控制的浅成中—高温热液型矿床,其形成与花岗岩的侵入密切相关,推测该矿床成矿时代为燕山早期,形成于古亚洲洋闭合碰撞向太平洋板块俯冲的构造转换期环境。

Jiaohe area in Jilin Province is located in the southern section of the Lesser Xing’an Range-Zhangguangcai Rang Fe-Pb-Zn-Cu-Mo-W metallogenic belt.In this area,the stratum and structure is well developed,and the magmatic activity is frequent.It has a good metallogenic condition In 2016,the No.1 Gold Geological Party of Chinese Armed Police Force carried out the 1/50 000 regional geological survey in this area.A gold deposit was found near Ailin region by stream sediment survey and anomaly verification.Field mapping coupled with laboratory research was conducted to investigate the mineralization geological characteristics and genesis of Ailin gold deposit in Jiaohe,Jilin Province.Field mapping suggests that the orebody is restricted by the NW faults and the wall rocks are mainly consisting of silty rock,belongs to Fanjiatun Group.The study of fluid inclusions shows that the homogeneous temperature of fluids is 240~400 ℃,the salinity is 7.5%~10.5%,the density is 0.75~0.90 g/cm3. The metallogenic pressure is 6.40~15.75 MPa.And the metallogenic depth is 0.64~1.60 km.It has the characteristic of epithermal mineralization and medium-high metallogenic temperature mineralization.H-O isotope analysis results show that δ18O values of fluids from fluid inclusions in quartz vary from 5.40‰ to 6.86‰,δD values of quartz from the ore change from -103.1‰ to -100.0‰,indicates that the water was derived mainly from mixed meteoric and magmatic water.Integrating the geological features of the region,orebody characters and analysis results,this paper comes to the conclusion that this deposit is of the medium-high temperature,closely related to the invasion of granite and the metallogenic age of the Ailin gold deposit is early Yanshannian,it was formed in the transition from the collision closure of Petro-Asian Ocean to the subduction of Pacific Plate.
