| 中文摘要: |
| 西溪堡锰矿位于扬子陆块东南部被动边缘褶冲带(铜仁逆冲带)与凤冈滑脱褶皱带的结合部位,为梵净山穹隆北东端外缘,属浅海斜坡相沉积环境。赋矿层位(含锰岩系)为南华系下统大塘坡组第一段,岩性为炭质页岩、黏土岩。矿体呈层状、似层状、透镜状,受层位、含锰岩系厚度、铁丝坳组岩性及厚度、古构造及沉积环境的控制。矿石矿物主要为菱锰矿、钙菱锰矿、锰方解石、锰白云石等。通过对该矿床地质特征、岩相古地理、古构造等综合分析,预测了深部锰矿找矿靶区。 |
| 英文摘要: |
| The Xixibao manganese deposit is located in the junction part of the fold belt (Tongren overthrust belt), southeastern passive continent edge of Yangtze plateform and Fenggang detachment fold zone, which is the northeastern edge of Fanjingshan dome.The deposit was formed in the slope facies of shallow sea, the ore-bearing bed,i.e.,Mn-bearing sequence is the first member of Datangpo formation of Lower Nanhua system, and the lithology of ore-bearing strata is carbonaceous shale and clay. The ore bodies occur in forms of bed, stratoid, and lenticular,which are controlled by strata, thickness of manganese-bearing layer, lithology and thickness of Tiesiao formation, and paleo-tectonic and deposition environment.The main ore minerals are rhodochrosite, calcium-rhodochrosite, manganese-calcite, manganese-dolomite.Based on the comprehensive analysis of geological characteristics of the deposit, lithofacies palaeogeography and paleo- structures, the prospecting targets in the depth are predicted. |
