| 摘 要： | 羌堆铜矿位于冈底斯斑岩型铜(钼)成矿带中东段的拉抗俄-吹败子铜(钼)矿集区内,是斑岩-夕卡岩复合型矿床,含矿斑岩体为花岗斑岩及石英斑岩,具全岩矿化特征,斑岩体与白垩系门中组灰岩的接触带形成夕卡岩型矿床.研究表明,地表和浅部出露的含矿斑岩体只是其岩枝,矿床剥蚀程度低,主斑岩体尚未出露,深部找矿潜力巨大.

| Abstract: | Qiangdui copper deposit is a porphyry-skarn complex copper(molybdenum) deposit located at the copper(molybdenum) deposit-concentrated Lahange-Cuibaizi area in the central east Gangdise porphyry copper(molybdenum) ore belt.The host rock is granitic porphyry and quartz porphyry which are wholly mineralized. The skarn copper(molybdenum) deposit occurs at the contact zone of the porphyry and limestone of Cretaceous Menzhong Formation.Our study reveals that the ore-bearing porphyry exposed at surface is only the apophyses and intense erosion did not take place thus the main porphyry are still at depth and it is potential for discovering big porphyry deposit to depth. |
