“铁帽”金矿现已尽人皆知。“锰帽”(主要指非锰矿锰帽、次生堆积锰矿或锰土等)对找Au、Ag矿的指示意义,似乎还未充分引人注意。“锰矿”中发现Au、Ag矿已不是个别现象。我国某些地方“黑土型”金银矿的发现,表明了“锰帼”的找矿指示意义。如大坊“黑土型”金矿,Au平均可达1.51g/t、Ag167g/t;七宝山锰土中含Au1.9g/t,Ag44.5g/t。栖霞山也是从氧化锰矿床开始,发现了Pb—Zn矿床,后又发现了伴生Au—Ag矿及单独Au矿体。在冷水坑铅锌银矿田中,从花岗斑岩体接触带向外,大致依次出现铁锰铅锌银
“Iron Hat” gold mine is now well-known. The indication of “Manganese Hats” (mainly referring to non-manganese ore manganese caps, secondary manganese ore or manganese earth, etc.) to find Au and Ag mines does not seem to have drawn enough attention. Found in the “manganese ore” Au, Ag ore is not an isolated phenomenon. The discovery of some “black-type” gold-silver mines in some parts of China indicates the significance of the “manganese 帼” prospecting. For example, in Dafang “black earth type” gold mine, the Au averaged up to 1.51g / t and Ag167g / t; and the Qibaoshan manganese contained Au1.9g / t and Ag44.5g / t. Qixia Mountain also started from the oxide manganese deposit and discovered the Pb-Zn deposit, then discovered the associated Au-Ag ore and the separate Au ore body. In Lengshuikeng Pb-Zn-Ag orefield, from the contact zone of granite porphyry body, there are generally iron, manganese, lead, zinc and silver
