大青南山金矿床位于黑龙江省北部，该区域是中国重要的有色、贵金属和能源矿产基地。通过系统总结已有资料，对大青南山金矿床地质特征进行了详细研究，矿区内圈出7个矿体，矿体产于碱长花岗岩中，受北东向断裂（构造蚀变带）控制，呈脉状、薄脉状北东向展布，矿石类型主要为含黄铁矿石英脉型和黄铁绢英岩型。围岩蚀变主要有钾化、硅化、绢云母化、绿泥石化等。矿床类型?械臀氯纫撼涮钍⒙鲂汀Ｍü肭蚰诔煽筇卣飨嗨频牡湫徒鹂蟠步卸员龋衔每笄畈烤哂辛己玫奶娇笄绷Γ⑼ü晏健⒖犹降忍娇蠊こ潭陨畈烤哂薪虾锰娇笄绷Φ那蚪辛斯こ萄橹ぁ＝峁允荆涸诳笄畈拷徊娇刂屏刷-1矿体，且探获了Ⅲ矿体、Ⅴ矿体等，共探获金矿石量（332＋333）494 399 t，金金属量2 399 kg，金平均品位4.85×10-6，探矿效果较好。通过对矿区进行深部探矿，获得了良好的探矿效果，可为矿区进一步探矿提供支撑。

Daqingnanshan Gold Deposit is located in the north of Heilongjiang Province,an important base in China of nonferrous and precious metals and energy mineral resources.Based on systematic summary of existing data,the geolo-gical characteristics of Daqingnanshan Gold Deposit are studied in detail.There are 7 orebodies delineated in the mining area.The orebodies occur in alkali feldspar granite and are distributed in veins and thin veins to NE direction under the control of NE trending fault (tectonic alteration zone).The ore types are mainly gold-bearing pyrite vein type and beresite type.Wall rock alteration mainly includes potassium alteration,silicification,sericitization,chloritization,etc.The type of deposit is medium-low temperature hydrothermal filling quartz vein type gold deposit.By comparing the typical gold deposits with similar metallogenic characteristics in the area,it is considered that the deep part of the mining area has good exploration potential,and the deep area with good exploration potential is verified through drilling,pit exploration and other exploration projects.The results show that the Ⅱ-1 orebody is further controlled in the deep part of the mining area,and the Ⅲ orebody and V orebody are detected.The total reserve of gold ores (332 ＋ 333) is 494 399 t,the reserve of gold metal is 2 399 kg,and the average grade of gold is 4.85×10-6,showing good prospecting effect.Through deep exploration in the mining area,good exploration results are obtained,providing support for further exploration in the mining area.
