柴家屯锰矿床已有20年的开采历史,为较大的富锰矿床.由于人们对该处特有的砾岩注意不够,故往往把目前所开采的主要矿体当成单纯的锰帽,或把硬锰矿、软锰矿矿床无区别的说成是内生的热液活动产物.笔者自1955年起借生产探矿之机,在此处进行了几次观察,证明该处锰矿床类型是复杂的,除了一部分是内生的菱锰矿床外,目前所开采的氧化锰矿床是一种淋滤溶洞充填矿床,在经济价值上占主要地位.这两种类型的锰矿床是不同时期的产物. The Chaijiantun manganese deposit, which has been mined for more than 20 years and is a large, manganese-rich deposit, often treats the main orebody currently being mined as a pure manganese cap or as a result of insufficient attention to the conglomerate congruent there The hard manganese ore, pyrolusite deposits are indistinguishable as endogenous hydrothermal activity products.The author from 1955 by the production of prospecting machine, where several observations made to prove that the type of manganese deposits in the area is complex , Except for a part of the endogenous rhodochrosite deposit, the currently developed manganese oxide deposit is a leached karst cave deposit, which is predominant in economic value, and these two types of manganese deposits are products of different periods.
