| 中文摘要: |
| 泥盆纪时期鸡街—篆角地区处于拉伸台盆—台地沉积环境，在早泥盆世—中泥盆世沉积了一套碳酸盐陡坡和深水硅质盆地、碳酸盐缓坡相间的岩石序列，其中中上部发现有硅质岩夹含锰泥岩岩系，本文通过对研究区内锰矿成矿的地质背景、含锰岩系层序分析、岩石组合特征、岩相古地理及成矿预测模式研究，进一步提高了该地区泥盆系达莲塘组含锰岩系的找矿认识，对该地区今后的找矿前景进行了分析。 |
| 英文摘要: |
| Data suggest that during the Devonian period, the Jijie-Zhuanjiao area, Yunnan was in an extensional platform basin-platform sedimentary environment. Wile during the Early Devonian-Middle Devonian period, a series of rocks with carbonate steep slopes, deep-water siliceous basins and carbonate gentle slopes were deposited. In this rock series, the siliceous rocks with manganese-bearing mudstone series were found in the middle and upper sections. This work analyzed the geological background, sequence of manganese-bearing rock series, combination characteristics of rocks, lithofacies palaeogeography and the metallogenic prediction model for the study area. It provides new insight into the search for of the manganese-bearing rock in the Devonian Daliantang Formation, and an analysis on the ore-search prospect in the future in this region. |
