Theoretical innovation, technology research and development, and frontiers on large-scale mapping of tectonic lithofacies

Demands of the nation and society are the forcing source for theoretical innovation, technology research and development on mapping of tectonic lithofacies. Moreover, theoretical innovation hse been achieved during the technology research and development on mapping of tectonic lithofacies. Then, R&D paradigm of the five-step-norms has been established as from the followings, normal lithofacies of dissection-modelling, tentative application and R&D focusing, demonstrating application and theoretical innovation, popularing demonstration and veri.cation of universality, integrated innovation and syncretic modeling. Tectonic lithofacies and geochemical lithofacies on the layers of the basement structure (pre-basin stage), the stage of basin formation, the stage of basin deformation, the stage of basin-in magmatic superimposing, the stage of basin with supergene variation, and their di.erent series of the diagenetic lithofacies have been carried out in important metallogenic basin and in the mosaic structure of basin-orogen-plateau. Achievements of main progress are as the followings. First, new classification scheme of the different series of the diagenetic lithofacies in basins was established. Second, a new method for the history of basin deformation had been put forward in order to uncover the formation mechanism for tectonic-magmatic-thermal events in basins. Third, comprehensive dissection-modelling methods of tectonic lithofacies for complex mineral systems were performed. Final, a new theory on hydrocarbon-rich metallogenic .uids with reductibility and predication was put forward, and the mineral system of the glutenite-type Cu-Pb-Zn-U deposits at the Western of Tarim Basin, therefore, a pioneer frontier for the mosaic structure of basin-orogen-plateau was been exploited. Based on reviews on the previous theoretical innovation, technology research and development on mapping of tectonic lithofacies, it is to be focused on safety of the ecological environment and resource in mines and meals concentrated-area, and to meet key demands of nation-society. It is urgent to probe on depth-in detection and syncretic models by tectonic lithofacies with multidisciplinary, while articial intelligence and big-data-platform technology is to aplly to theoretical innovation, technology research and development on mapping of tectonic lithofacies.
