470矿区是个工作近二十年的老区。近年来在前人工作基础上,综合分析了全区资料,进一步研究了矿区地质构造特征,提出了矿区是受火山塌陷构造控制的新认识;同时对矿区地层层序及其时代归属作了较大的变动,认为含矿围岩-粗面岩应归属于侏罗纪。
470 mining area is a working area for nearly 20 years old. In recent years, based on the previous work, a comprehensive analysis of the data of the region to further study the characteristics of the geological structure of the mining area, proposed that the mining area is controlled by the volcano collapse structure of the new understanding; at the same time stratigraphic sequence and the ownership of the mine made Large changes, that ore-bearing wall rocks - Rough rocks should be attributed to the Jurassic.
