| 中文摘要: |
| 大脑坡铅锌矿位于扬子微板块—上扬子地块东南部边沿与江南地块的过渡带上,含矿岩系为寒武系下统清虚洞组下段第三、四亚段厚层—巨厚层质纯微—细晶灰岩(藻灰岩和鲕粒灰岩、砂屑灰岩),有7个矿层,13个亚层,连接25个矿体,总体呈似层状、顺层透镜体状产出。文章总结大脑坡铅锌矿地质特征,分析了控矿因素中地层、岩相、岩性、构造及围岩蚀变与成矿关系,探讨了矿床成因,指出了找矿标志。 |
| 英文摘要: |
| Danaopo lead-zinc deposit is located in the Yangtze plate-on the the transitional zone of the southeastern edge of Upper Yangtze massif, called Yangtze plate, and jiangnan massif. The ore-bearing rock series are the group of the third and fourth the paragraphs under thick layer-the thick layer of pure quality micro-fine grain limestone(algal limestone and oolitic limestone, calcarenite) in the lower Cambrian system. There are 7 mineralization layers and 13 sub-layers connecting 25 orebodies. The orebosies presented as stratoid beds and lenticular beds in view of the overall situation. This paper summarized the geological characteristics of Danaopo lead-zinc deposit, analyzed ore-forming factors including strata, rock facies, lithology, structure and surrounding rock alteration and metallogenic relationship, discussed the deposit’s genesis, and show the indicator for exploration. |
