陆相红色盆地如何开展1:5万区域地质调查?地矿部江西地勘局地矿调研大队技术人员“八五”期间,做了大量有益的探索,取得了新的进展,提出了构造—岩性—岩相填图方法。 “八五”期间,地矿部江西地勘局有针对性地在吉安—泰和、信江、武宁、安义、锦江陆相红色盆地中安排了27幅1:5万区域地质调查工作。特别是江西地矿调研大队在吉泰盆地的系统调查,通过实践提出了陆相红色盆地1:5万填图方法:构造—岩性—岩相填图法。即从划分构造界面入手,以岩性、岩相调查为主线,调研各类构造界面、沉积界面的性质和沉积体的物质组成、结构特征、形成环境、时空展布及相互叠置关系,正确建立陆相岩石地层层序、划分岩石
How to carry out 1: 50000 regional geological survey in the terrestrial Red Basin? During the “Eighth Five-Year Plan” period, the geotechnical research team of the Geological and Geochemical Exploration Bureau of the Ministry of Geology and Mineral Resources made a great deal of useful explorations and made new progresses. Lithology - lithofacies mapping method. During the “Eighth Five-Year Plan”, Jiangxi Bureau of Geology and Mineral Resources of the Ministry of Geology and Minerals arranged 27 1: 50000 regional geological surveys in a targeted manner in the terrestrial red basins of Ji’an-Taihe, Xinjiang, Wuning, Anyi and Jinjiang. In particular, a systematic survey of the Geological Research Brigade in Jitai Basin of Jiangxi Province has put forward a 1: 50000 mapping method of terrigenous red basins by practice: tectono-lithology-lithofacies mapping. That is to say, starting from the division of the structure interface, taking the lithology and facies investigation as the main line, we investigated the various types of structural interfaces, the nature of the sedimentary interface and the material composition and structural characteristics of the sedimentary bodies, and formed the environment, space-time distribution and mutual overlapping relationship Establish a sequence of continental lithostratigraphy and divide rocks
