早在本世纪二十年代,A.Locke、R.Blanchard(1922)和P.E.Boswell(1923)等在研究美国西部铜矿床时,第一次提出了一套能指示原生硫化物的铁帽的结构构造。后来R.Blanchard又长时间地做了这方面的工作,并有许多著作。苏联学者(1952)、(1958)也曾报道过东外贝加尔和穆戈扎拉地区多金属矿床中铁帽的结构构造,其它国家亦有一些个别矿床的零星报道。我国在六十至七十年代,华东地质科学研究所在进行长江中下游硫化物矿床氧化带及铁帽评价研究的工作中,对该区硫化物矿
As early as the 1920s, when A. Locke, R. Blanchard (1922) and PEBoswell (1923) studied the copper deposits in the western United States, for the first time, a set of iron caps that can indicate primary sulfides Structure construction. Later R. Blanchard and a long time to do this work, and there are many books. Soviet scholar (1952) and (1958) also reported the structure of iron caps in polymetallic deposits in the eastern Baikal and Mugozara regions, while other countries reported sporadic reports of individual deposits. In the sixties to the seventies, China’s East China Institute of Geological Sciences in the middle and lower reaches of the Yangtze River sulfide ore oxidation zone and iron cap evaluation of the work of the area sulfide minerals
