Main Progress and Achievements of Strategic Mineral Prospective Survey Project of Nylonma Area, Tibet

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.
