| 中文摘要: |
| 祁宝钨钼矿床矿化受岩性控制,钨矿化主要与夕卡岩有关,钼矿化主要与花岗岩及其岩脉有关;该矿床钨钼元素具有明显的分带性:在水平方向上,以岩体为中心,由内向外钨含量由低→高→低,钼含量由高→低;在垂直方向上,钨含量由低→高→低,钼含量由低→高;根据该矿床钨钼元素的平向变化规律与垂向变化规律,推测该矿床西北角中部和深部夕卡岩及其夕卡岩化角闪云母片岩是今后找钨的首选地段、中部深部花岗岩体及其两侧花岗岩脉是今后找钼的首选地段。建议在地质找矿工作中,对祁宝矿床西北角中部和深部夕卡岩及夕卡岩化角闪云母片岩、中部花岗岩体及两侧花岗岩脉进行工程验证和控制,以期发现富大钨、钼矿体。 |
| 英文摘要: |
| Qibao W-Mo deposit is controled by lithology. W mineralization is closely related to skarn,Mo to granite and related dykes.W, Mo in the deposit show strong zonation.Horizontally W distribution is characterized by low→high → Low from the center of the whole rock body to the outside and Mo by high→ low;vertically W by low → high → low,Mo by low → high.Based on the distribution pattern we postulate the medium-deep skarn and skarnized hornblend-mica schist in northwest corner of the deposit to be the target for W ore and the medium-aeep granite and related dykes on the either sides for Mo ore and propose to layout workings at the targets. |
