近年来,我国在中南、华北、东北及西南不少省先后在石炭纪、二叠纪、第三系不同的地质时代发现煤系内沉积黄铁矿,有的矿区作了地质勘探工作,查明了一定的地质储量。本文是对石炭纪地层内煤系沉积黄铁矿地质特征作初步探讨,由于了解资料很不全面,错误之处,尚待批评指正。 In recent years, many pyrites have been found within the coal measures in different geologic periods of Carboniferous, Permian and Tertiary in central and southern China, northern China, northeast and southwest China, and some have made geological exploration work. Clear a certain amount of geological reserves. This article is a preliminary study on the geological characteristics of coal-bearing sedimentary pyrite in the Carboniferous strata. The understanding of the data is incomplete and wrong, awaiting criticism and correction.
