| 中文摘要: |
| 研究区华力西期基性喷出岩系具明显的旋回性和韵律性,属滨-浅海相喷发-沉积环境。随着区内华力西期基性岩浆演化分异作用的进行,其含矿性(铜、铅、锌等)呈现递增的变化规律。第Ⅲ、Ⅳ旋回玄武岩系(P2β3和P2h)是区内重要的矿源层和赋矿层位。 |
| 英文摘要: |
| Variscan basic extrusives with distinct cyclicity erupted and deposited from littoral region to epeiric sea during variscan period. In pace with the Variscan basic maginatic differentitation, its ore-bearing property (meaning content of Cu、Pb、Zn etc) is progressively increasing. The basaltic formation of the third and fourth cycle (P2β3 and P2h)is the important ore Source and ore bed in this district. |
