| 摘 要： | 鹤庆锰矿,赋存于印支运动形成的东西向裂陷槽中,成矿时限应早于松桂湖的中、晚北衙期,分出同生沉积型和淋滤充填型。控矿构造为特殊的向斜轴部“锅底凹”,成因属于火山热液同生沉积、后期改造型锰矿床。

| Abstract: | The Heqing Mn deposit exists in the Indosinian EW fault depression. The metallo- genetic time must be earlier than the middle--late Beiya stage of Songgui period, which can be divided into the cogenetic sedimentation type and the leaching filling type. The ore - controlling structure is the special ＂sag of pot bottom＂ of synclinal axis. The genesis belongs to the volcanic hydro- thermal cogenetic sedimentation and posterior reformation type Mn deposit. |
