中文摘要:
      郎郡哈拉金多金属矿床处于赤峰-开原金矿集区内,其地层、构造、岩浆岩均具有较好的成矿地质条件。根据1∶1万地面高精度磁法、激电中梯、土壤测量及槽探验证等多种工作手段,确定了郎郡哈拉金多金属矿床存在2条金、铜矿化蚀变带Sb-1、Sb-2。Au最高品位达9.1×10-6,平均3.56×10-6。根据矿石、矿物组成及围岩蚀变特征,认为郎郡哈拉金多金属矿床为中低温热液改造的石英脉型矿床,金矿体受构造裂隙控制。在总结郎郡哈拉金多金属矿床地质特征及成因模式基础上,确定郎郡哈拉外围三间房地区具有一定成矿潜力,可进行下一步工作。
英文摘要:
      The Langjunhala Au polymetallic deposit is located in the Chifeng-Kaiyuan gold concentration area. Its strata, structure and magmatic rocks all have good metallogenic geological conditions. According to 1:10000 high-precision surface magnetic method, IP middle ladder, soil measurement, trenching verification and other working methods, it is determined that there are two alteration zones of gold and copper deposits in Langjunhala Au polymetallic deposit:Sb-1, Sb-2. According to the characteristics of ore, mineral composition and surround rock alteration, Langjunhal Au polymetallic deposit is considered tu be a quartz vein type deposit transformed by medium and low temperature hydrothermal solution. The gold body is controlled by structural fracture. On the basis of summarizing the geological characteristics and genetic model of the Langjunhala Au polymetallic deposit, it is determined that the Sanjianfang area around the Langjunhala Au area has certain metallogenic potential, and the next work can be carried out.
