在炭质岩和碳酸盐岩石的近地表部分,从低温热液到热泉(Hot-SPring)的环境中产出有一种低品位,大储量的浅部浸染型金银矿床.许多人(最近有Radtke等,1980)对此已有所论述.由于金银价格大幅度上涨,所以直到最近,很多这种类型的矿床才显示出其经济价值.人们也开始把注意力从以碳酸盐为寄主岩的典型卡林型金矿移到了这种类型的大型金矿上,并且在这方面研究已经开始有所进展.本文所述的矿床具有如下待点:出露浅,浅成低温热液热泉成因,矿化呈浸染状和(或)网脉状,但不以碳酸盐岩石为寄主岩而常产在火山岩和(或)火山碎屑岩中.值得一提的是,这些岩石常含有长英质组分.
In the near-surface parts of carbonaceous rocks and carbonate rocks, a low-grade, large-reserve shallow disseminated gold-silver deposit is produced from the cryogenic hydrothermal to hot-spring environments.5 Many people ( Recently reviewed by Radtke et al., 1980), and until recently, many of these types of deposits have shown their economic value because of the substantial increase in the price of gold and silver, and attention has also begun to shift from the use of carbonate Typical Carlin-type gold deposits hosted by the host rock have been migrated to this type of large-scale gold deposit and research has begun to progress in this area. The deposits described herein have the following points: shallow, shallow to low temperature The origin of the hydrothermal springs is disseminated and / or reticulated in mineralization but is not commonly found in volcanic rocks and / or pyroclastic rocks, not hosted by carbonate rocks. It is worth mentioning that these Rock often contains long British quality components.
