引言在太古宙,火山-沉积岩层遍布于全世界,金与条带状铁建造有一种联系。围绕这种联系的性质和同生成因与后生成因模式引起了争论。就津巴布韦一些矿床来说,Fripp(1976)提出了赞成铁建造容矿金矿床为同生成因的证据。对巴西马里亚纳的帕萨格姆矿床而言,Fleischer和Routhir(1973)也提出了赞成铁建造容矿金矿床为同生成因的证据。Page(1979)认为,西北地区的卡拉通湖金矿床也是同生成因的铁建造容矿的 INTRODUCTION In the Archean, volcanic-sedimentary formations are all over the world and gold has a connection with banded iron. The controversy surrounding the nature of this connection and the model of co-generation and subsequent generation. For some of the deposits in Zimbabwe, Fripp (1976) presented evidence in favor of the fact that the iron ore-bearing ore deposit is an anomaly. For the Pasaglm deposit in Mariana, Brazil, Fleischer and Routhir (1973) also present evidence in favor of the genesis of an iron-built ore-bearing gold deposit. Page (1979) argues that the Kalatonghu gold deposit in the Northwest is also a causal iron-making mineral
