| 摘 要： | 项目以铜铅锌银为主攻矿种，以层控型、矽卡岩型铜多金属矿等为主攻矿床类型，采用1∶5万地质填图、地面高磁测量、水系沉积物测量和遥感地质解译等为工作方法，基本查明了区内矿产地质背景，共圈定各类异常111个，提交了3处新发现矿产地，建立了铜铅锌矿床的找矿标志及找矿模型，圈定8个成矿远景区和23处找矿靶区。首次在研究区新发现念青唐古拉岩群、蛇纹石化橄榄岩和云英岩-矽卡岩型铜钨矿床及矽卡岩型铋矿床、矽卡岩型铟矿床;首次在念青唐古拉地区厘定来姑组和马里组2个具有重要找矿意义的控矿层位，提出了该地区同生沉积、后期改造的区域成矿模式。为该地区进一步地质调查、矿产勘查规划与开发提供丰硕的基础资料。

| Abstract: | In this project, the stratabound type and skarn type copper, lead, zinc, silver polymetallic deposit was selected as the main exploration target. We revealed the regional metallogenic geological background; found 111 mineralization anomalies; submitted 3 mineral deposits, 8 metallogenic areas and 23 prospecting target areas; established the prospecting indicators and prospecting model basing on a set of exploration methods includes 1:50000 geological mapping survey, ground magnetic survey, stream sediment survey, and remote sensing geological interpretation. In addition, we have the following new discoveries: 1) we recognized the Nyainqentanglha group complex, serpentinized peridotite and greisen-skarn type copper-tungsten deposit, skarn type bismuth deposits and indium deposit in the study area; 2) we found the Laigu formation and Mali formation have important exploration significance in Nyainqentanglha region, and proposed the regional sedimentary-transform metallogenic model. All these progress and achievements provide fruitful basic materials for further geological survey, mineral exploration and development. |
