中文摘要:
      贵州遵义地区是我国二叠纪锰矿的重要分布区之一,深溪锰矿是遵义地区继铜锣井锰矿发现的第二个大型隐伏锰矿床。本文结合深溪锰矿找矿实践,详细总结了深溪锰矿床地层、构造、矿石等特征,并对锰矿的矿床成因进行了探讨。研究表明,深溪锰矿严格受地层层位控制,呈层状、似层状产于二叠纪茅口组第三段浅灰至灰黑色含锰岩系中,矿石矿物主要为菱锰矿,含少量黄铜矿、重晶石、毒砂等矿物,矿石为块状、斑杂状、角砾状构造,自然类型为碳酸锰矿石,工业类型为贫锰矿、富锰矿。分析认为深溪锰矿为深部的气液成矿物质喷溢至地堑盆地中沉积成矿,为“内生外成”的“古天然气渗漏沉积型锰矿床”。
英文摘要:
      Zunyi of Guizhou Province is one of the important distribution areas of Permian manganese deposits in China.Shenxi manganese deposit is the second founded large concealed manganese deposit deposit after Tongluojing manganese deposit.In this paper,it combines the mining practice of shenxi manganese deposit,the characteristics of strata,structure and deposit in Shenxi manganese deposit were summarized in detail,and the genesis of the deposit is discussed.The study shows that the Shenxi manganese deposit is strictly controlled by strata and occurs in layered and layered manganese-bearing rocks of the third member of the Permian Maokou Formation.The deposit minerals are mainly rhodochrosite,containing a small amount of chalcopyrite,barite,arsenopyrite and other minerals.The deposit is massive,porphyry,breccia-like structure and the natural type is carbon.Acid manganese deposit,industrial type is poor manganese deposit,rich manganese deposit.It is considered that the Shenxi manganese deposit is a deep gas-liquid metallogenic material spilled into the graben basin to deposit and mineralize,for ‘endogenous’ ancient sedimentary manganese deposit type gas leakage.
