中文摘要:
      黔东及毗邻地区南华纪锰矿成矿期构造主要为同沉积断层,该类型断层在成矿期十分发育,控制和形成了南华纪早期不同序次的次级裂谷盆地,同沉积断层的垂向发育形成了锰矿成矿通道,同沉积断层可作为古天然气渗漏沉积型锰矿床关键地质找矿标志,本文阐述了其主要判别特征。南华纪锰矿形成后,历经加里东运动、印支运动及燕山运动等构造运动,总体来说,该区构造格局主要是受到燕山运动影响形成。本文也讨论了研究区成矿后广泛发育且比较典型,对锰矿层保存与破坏有着较大影响的犁式正断层及其判别特征。
英文摘要:
      The manganese metallogenic structure of Nanhua period in east Guizhou and its adjacent area mainly are synsedimentary fault,this type of fault is very developed in the metallogenic period,it controlled and formed the secondary rift basin of different sequences in early Nanhua period.The vertical development of synsedimentary fault formed the manganese metallogenic channel,so the synsedimentary fault can be geological prospecting marks of ancient natural gas seepage sedimentary-type manganese deposit.In this paper,the main distinguishing features are expounded.After the formation of Nanhua Period manganese ore,it underwent Caledonian,Indosinian and Yanshanian movements,the formation of structural framework in this area was effected by Yanshanian movement generally.It also discusses the characteristics of listric normal faults which are widely developed and typical after mineralization and have great influence on the preservation and destruction of manganese ore layers.
