我們工作地区广泛分佈的是前震旦紀片麻岩系,在片麻岩中找銅,无論在地質或物化探来说都是新課题。經过三年来工作,我們在这古老的地台上找到了較大的铜矿床,从而打破了“片麻岩中无矿”的錯誤論調。这里所介紹的只是經实踐后获得初步效果的实际結果。文中只着重定性的說明而没有罗列理論計算和定量推断。地質情況簡介清原地区內主要岩石力片麻岩,分正付片麻岩,前者为火成变質即花崗片麻岩系,后者为水成变質即
The widespread pre-Sinian gneiss line in our area of work and the finding of copper in gneisses are new topics both in geology and in geophysical and geochemical exploration. After three years of work, we have found a larger copper deposit on this ancient platform, thus breaking the erroneous argument that “there is no ore in gneiss.” All that is presented here is the actual result of obtaining the initial result after practice. The text only focuses on the qualitative description but does not include the theoretical calculation and quantitative inference.
