| 在通过对大塘坡矿区所有钻孔原始资料以及野外地层剖面整理、分析研究的基础上，运用锰矿裂谷盆地古天然气渗漏沉积成矿系统理论关于中心相、过渡相和边缘相判别标志，在断陷盆地中心的渗漏喷溢口及附近，分布有大量的古天然气渗漏喷溢构造，如底劈构造、渗漏管构造、软沉积变形纹理等，特别是出现被沥青充填的气泡状构造的菱锰矿石是其关键标志。综合分析认为该矿区至少存在三个古天然气渗漏喷溢口，构成"一大两小"、十分罕见的古天然气渗漏喷溢口群。每一个喷溢口，即构成一个相对独立的古天然气渗漏喷溢沉积成矿系统，各自的中心相、过渡相和边缘相独立完整。故大塘坡锰矿床是形成于由三个古天然气渗漏喷溢沉积成矿子系统构成的一个统一的、复杂的古天然气渗漏喷溢沉积成矿系统。该发现对于研究古天然气渗漏沉积型锰矿床成矿系统成矿模式与找矿模型具有重要意义。 |

| This paper discusses the characteristic of manganese in Datangpo mine on the basis of sort out and analysis for the sourcebook about all drilling and observations of stratigraphic sections，to use of the discrimination flag of the center phase、the transition phase and the edge phase about the ancient gas leakage sedimentary metallogenic system in manganese rift basinIn the leakage eruption port and the near center of the phase region of the center of the rift basin，there is a large number of structure about the ancient gas leakage eruption port，such as the diapiric structure，the leaking pipe structure，the soft sediment deformation bedding，etc，especially the rhodochrosite with the bubble-like structure which is filled by asphalt is the key symbol. In Datangpo mine，a large number of the typical structure about bubble-like structure，mud volcanic structure，diapiric structure and etc has been foundComprehensive analysis that there is at least three ancient mine gas leak eruption ports in the mining，that a leak effusive port groupThe found of the eruption port group has esplained that the ancient gas leakage eruption and the mineralization of manganese in Datangpo mining on the early Nanhuan is complexIn the place，there are three eruption ports about one big and two small，constitute a very rare ancient gas eruption port groupEach eruption port constitute a relatively independent ancient gas leakage eruption sedimentary mineralization system，respective central phase，the transition phase and edge independently completeTherefore Datangpo manganese deposit is formed in a unified complex ancient gas leakage eruption sedimentary mineralization system which is composed of three subsystems of the ancient gas leakage eruption sedimentary mineralization systemThis finding is of great significance for the study metallogenic model and prospecting model of the ancient gas leakage sedimentary manganese deposit metallogenic system |
