贵州省遵义锰矿为国家级整装勘查区，近年来，通过不断的勘查和综合研究，利用理论指导勘查实践，研究区取得了重大的找矿突破，并发现大型锰矿床数个。在前人研究的基础上，拟从遵义锰矿的岩相古地理特征、成矿环境、成岩期改造的角度进行分析、探讨。认为遵义锰矿区分布在中二叠世茅口晚期台沟相带内，总体呈一同心圆状，由外向内分别是粘土岩硫铁矿相-台沟边缘相-台沟中心相，其中，台沟中心相锰矿集中、富集、价值大；该区锰矿形成于弱碱性、弱氧化还原、较封闭的成矿环境中，成矿过程所需的热能，主要来源于岩浆活动，其次可能还与该区处于古地热异常高值区有关；成岩期的改造也是遵义锰矿成矿的重要因素。拟为进一步研究锰矿的成矿机制提供理论依据。

The Zunyi manganese ore is the national self-contained manganese exploration area.In recent years,the Zunyi manganese ore is national ready exploration area of Guizhou Province.Through continuous exploration and comprehensive study,this paper uses the theory to guide exploration practice,has major prospecting breakthroughs in the study area,and finds several large manganese ore bed.On the basis of previous studies,this paper makes an analysis from Zunyi manganese ore,lithofacies palaeogeographic characteristics, metallogenic environment and diagenetic phase transformation.This paper holds that Zunyi manganese ore zone is distributed in the late Permian in brussel mouth sets trench facies belt,generally showing a concentric circle. Outside-in respectively is pyrite phase-clay rock gully edge phase-taigou groove center,among which the taigou groove center is in manganese concentration,and has the big value.Manganese ore in the area is formed in weak alkaline,REDOX,and relatively closed metallogenic environments.Firstly,the heat needed for the ore-forming process is mainly derived from magma activity;secondly,it is probably related to the area in the ancient geothermal anomaly high value area.Diagenetic stage of transformation is also an important factor of Zunyi manganese mineralization.This paper provides the theoretical basis for further research of manganese ore and metallogenic mechanism.
