| 摘 要： | 西藏恰我铁钨多金属矿床是近年来在冈底斯成矿带上首次发现的矽卡岩型铁钨多金属共生矿床。通过1∶5万水系沉积物异常区开展大比例尺土壤化探测量,圈定了4个成矿元素以W、Pb为主综合异常;经物探高磁和激电测量进一步缩小了找矿范围和圈定了靶区,并通过工程验证找到了资源量达中型规模矽卡岩型铁多金属矿床。采用物化探方法找寻矽卡岩型铁多金属矿体可取得良好的找矿效果。实践证明,在冈底斯成矿带上寻找矽卡岩型铁矿或铁铜矿的同时,还应注意矽卡岩型铁钨(钼)多金属共伴生矿床的寻找。

| Abstract: | The Qiawo deposit in Tibet is the first skarn type iron-tungsten polymetallic deposit discovered in Gangdese metallogenic belt in recent years.Four W、Pb-dominant comprehensive anomalies are outlined by means of the large scale soil geochemical survey on basis of stream sediment survey at scale 1 ∶ 50000.Then high-precision magnetic survey and IP survey are carried out to reduce the prospecting area and locate targets and middle size Fe-metallic deposit is encountered by prospecting workings.Geophysical and geochemical technology is effective to locate skarn type Fe-W (Mo) deposit.Attention should be paid to skarn type Fe-W (Mo) deposit during prospecting of skarn type Fe deposit and Fe-Cu deposit in Gangdese metallogenic belt. |
