鹤庆锰矿矿石品位高达62．36％，该锰矿形成于浅海局限环境. Ce正或负的异常显示该矿床形成于海平面震荡的条件下.镜下可见早期矿物为菱锰矿，后被氧化为水锰矿或黑锰矿，品位升高.综合分析认为高品位矿石的形成经历了三个阶段：局限环境下锰质高度富集；因介质性质转变而成矿；表生作用阶段矿石品位升高.

Heqing manganese deposit with ore grade arriving at 62.36% formed in a restricted shallow water environment. Positive or negative abnormality of Ce supports that this deposit formed under the condition that sea level shocked. The mineral formed in the first stage is rhodochrosite,which was oxidized into manganite or hausmannite later,with grade elevated. Comprehensive studies show that the formation of high grade manganese ore experienced three stages:manganese concentrated under restricted shallow water environment;mineral formed as media properties changed;the grade of manganese ore becoming higher during supergene stage.
