| 中文摘要: |
| 斯弄多铅锌矿区位于冈底斯-念青唐古拉板块的隆格尔-工布江达弧背断隆带南缘的铅锌多金属成矿带内。通过激电测量工作,在矿区获得12个异常。经过评价解释,筛选出具有找矿价值的异常5个,其中南部地区2个、北部地区3个。南部地区的异常有JD1号异常,包含5个异常高值区,JD1-3为已知矿化异常。根据异常特征和成矿地质条件,将JD1号异常划分了3个远景区:Ⅰ号远景区由JD1-1号异常构成,Ⅱ号远景区由JD1-2号、JD4号异常和KHT1号、KHT2号矿化体组成,Ⅲ号远景区由JD1-3构成,Ⅲ号远景区可作为下步工作的重点地段。 |

| Sinongduo Pb-Zn ore area is geotectonically located in the south margin of Longer-Gongbujiangda back arc uplift belt of Gangdisi-Nianqing Tanggula plate.IP survey delineates 12 anomalies.Five of 12 anomalies are screened out through interpretation and evaluation.Two of the five is in south of the ore area and 3 in the north.They are of significance to ore exploration.Anomaly JD1 in the south includes 5 high abnormal value zones of which JD1-3 anomaly is caused by the known mineralization and others also significant to ore exploration.On basis of the anomaly characteristics and the geological and metallogenic condition 3 prospects are lineated.Prospect I is composed of anomaly JD1-1;prospect II anomaly JD1-2,JD4 and mineralized body KHT1 and KHT2;prospect III anomaly JD1-3.Prospect III is the focus for next exploration that will guide future exploration in the area. |
