中文摘要:
      那阿钨多金属矿床是西藏三江地区发现的矽卡岩型钨矿床,为完善区域钨锡矿床成矿谱系和成矿规律研究意义重大。为有效扩大矿区潜在资源量,开展了大比例尺地面高精度磁法测量工作,研究结果表明:那阿钨多金属矿床以矽卡岩型矿体为主,可见少量的云英岩化型白钨矿体,矿物以白钨矿为主,见少量锡石、辉钼矿;共圈定出磁异常9处,矽卡岩、矽卡岩化大理岩具有较为接近的磁化率,属于中等弱磁异常;经深部探矿工程验证,其中6处磁异常为矿致异常,剩余3处磁异常有待进一步验证,但在地表已发现星点状白钨矿化,具有较大的找矿潜力。
英文摘要:
      The Na’a tungsten poly metal deposit is the only case of tantalum-based tungsten deposit found in the Sanjiang region of Tibet, which is of great significance for the study of the mineralline lineage and mineralization law of the regional tungsten tin deposit. In order to effectively expand the potential resources of the mining area, a large proportion of the ground high-precision magnetic measurement work, the results show that:Na a tungsten multi-metal deposit to the tantalum-type ore-based, visible a small number of Yunying rockized white tungsten ore, minerals to white tungsten mainly, see a small amount of tin Stone, hui-yin ore; a total of 9 magnetic anomalies were determined, the zircona rock, the yanka rock dali rock has a relatively close magnetization rate, belongs to the medium weak magnetic anomaly; The remaining 3 magnetic anomalies need to be further verified, but star-spot white tungsten mineralization has been found on the surface, which has great potential for prospecting.
