[Abstract]:Neotectonics survey is the basis of studying crustal movement, geological hazards, environmental geology and crustal stability evaluation. It has important theoretical and practical significance and is one of the important contents of regional geological mapping. The 1: 50 000 mapping pilot area of Hulerusumu map in Inner Mongolia is located in the Yinshan-Hetao basin conjunctive zone, with frequent neotectonic activities, complex stratigraphic structure, abundant structural and geomorphologic forms, and extensive development of the front mountain faults. It is an ideal place to investigate and study neotectonic movement. In this study, based on the previous regional mapping theory, the geochronology of field route survey sections (including borehole sections) was interpreted by remote sensing for different neotectonic mapping objects such as Cenozoic strata, faults and tectonic landforms. Remote Sensing interpretation of Field tracing Survey Comprehensive Geophysical and Geochemical Geological Radar Exploration trough Disclosure of Three-dimensional Laser scanning chronology method, Remote sensing interpretation of field survey geochronology and other different technical and methodological combinations are investigated and studied, with reference to the relevant technical requirements such as the General principles of Regional Geological Survey (1: 50000) and the Technical requirements of < 1: 50000 Regional Geological Survey (provisional) >. By using digital mapping technology, the mapping results are intuitively, richly and detailedly expressed on geological maps. The combination of the new structural mapping techniques and methods is not only an effective exploration of the new structural mapping methods, It also provides an important reference for a new round of large scale neotectonic mapping in other regions.
