摘　　要：贵州遵义高山锰矿床位于张家湾-木杠台Ⅳ级地堑盆地内,通过利用高山锰矿勘查成果,较详细地总结了矿床地质、矿体地质和矿石特征。区内锰矿体赋存于茅口组第三段,呈透镜体、似层状产出,产状与地层一致,矿石矿物成分为菱锰矿、软锰铁矿、褐铁矿,主要脉石矿物有硅质、黏土矿物等;矿石具胶状结构、晶粒状结构和块状构造,Mn平均含量为20.79%,矿区Mn矿石品位总体由南向北变高。锰矿石自然类型为碳酸锰矿石;矿石工业类型为高铁、低磷铁锰矿石。矿床成因属内生外成气液喷溢沉积型锰矿床。The Gaoshan Manganese deposit in Zunyi,Guizhou province is located in the zhangjiawan-muguatai graben basin of grade IV.Based on the exploration results of the Gaoshan Manganese deposit,the geology of the deposit,the orebody and the ore characteristics are summarized in detail,the manganese ore bodies occur in the third section of the Maokou formation as lenticular and bedded occurrences,which are in accordance with the strata.The ore minerals are composed of rhodochrosite,pyrolusite and limonite,the main gangue minerals are siliceous and clay minerals.With colloform texture,crystalline granular texture and massive structure,the average content of Mn is 20.79%.The Mn ore grade in the mining area is generally higher from south to north.The natural type of manganese ore is manganese carbonate ore,and the industrial type of manganese ore is with high iron and low ferrophosphorus.The genesis of the deposit belongs to endogenetic and endogenetic gas-forming liquid spouted sedimentary manganese deposit.
