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。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.
