| 摘 要： | 大理-瑞丽铁路属于泛亚铁路南线的重要组成部分。为解决铁路工程建设过程中面临的复杂地质问题，中国地质调查局在2008年1月至2010年12月期间组织实施了1∶5万区域地质调查与环境灾害专项调查，共设置了6个工作项目，包括22个1∶5万国际分幅的调查和1个综合研究项目。通过系统的区域地质调查和研究工作，在构造、岩石、地层、古生物等基础地质方面有大量的新发现，获得了一批高精度的锆石U-Pb年龄数据，认为保山地块应归属于冈瓦纳大陆。调查过程中发现了潞西构造混杂岩带，并认为其属于怒江构造混杂岩带的组成部分。

| Abstract: | The Dali-Ruili railway is an important part of the south line of the Fanya railway. In order to solve the complex geological problems in railway building, China Geological Survey carried out 1∶50000 regional geological mapping and environment hazard investigation from January 2008 to December 2010. Six working items were set up, which included twenty-two 1∶50000 mapping items and one comprehensive research item. Important progresses were made in such basic geological aspects as structure, petrology, strata and paleontology through systematic regional geological survey. A number of high-precision age data were obtained. The Baoshan block is considered to be a part of the Gondwana continent. Luxi tectonic melange belt was discovered, which is thought to be a part of the Nujiang tectonic melange belt. |
