摘　　要：遵义小金沟锰矿床位于遵义锰矿成矿亚带内,受铜锣井Ⅳ级断陷盆地控制,总体呈单斜构造,属于“内生外成气液喷溢沉积型锰矿床”,以茅口组第3段含锰岩系粘土岩为主要赋矿层位,矿石矿物以碎屑结构、块状构造菱锰矿为主。The Xiaojingou manganese deposit is located in the sub-metallogenic zone of the manganese deposit in Zunyi.Controlled by the Tongluojing IV fault basin,the deposit with an overall monoclinic structure is an endogenous and exogenous sedimentary one of gas-liquid eruption.The manganese-bearing claystone of the third member of the Maokou Formation is the main ore-bearing horizon,and the minerals are mainly rhodochrosite of clastic structure and massive structure.
