发布时间：2018-09-09 11:46
【摘要】：新构造调查是研究地壳运动规律、地质灾害、环境地质和地壳稳定性评价等的基础,具有重要的理论和实际意义,是区域地质填图重点内容之一。内蒙古呼勒斯太苏木图幅1:5万填图试点区,位于阴山—河套盆地结合带,新构造活动频繁,地层结构复杂,构造地貌形态丰富,山前断裂广泛发育,是调查研究新构造运动的理想场所。本研究在前人区调方法理论基础上,针对新生代地层、断裂、构造地貌等不同的新构造填图对象,分别使用遥感解译+野外路线调查+剖面(含钻孔剖面)实测+年代学方法、遥感解译+野外追索调查+综合地球物理+地球化学+地质雷达探测+探槽揭露+三维激光扫描+年代学方法、遥感解译+野外调查实测+年代学等不同的技术方法组合进行了调查研究,并参照《区域地质调查总则》(1∶50000)、《1:50000区域地质调查技术要求(暂行)》等有关技术要求,采用数字填图技术,将填图成果直观、丰富、详细的表达在地质图上,该新构造填图技术方法组合,不仅是对新构造填图方法的有效探索,也为其它地区新一轮大比例尺新构造填图提供了重要参考。
[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.
