| 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. |
