摘要

Since 2003, China Geological Survey has assigned more than 30 1∶250 000 and a few 1∶50 000 mapping tasks in Qiangtang area, various types of scientific researches have been developing actively, which has achieved a large number of important results of regional geological investigation and scientific research. Significant progress has been obtained regarding the constitution, age and nature of the basement in central Qiangtang where Paleozoic formations are widely distributed, further study has been accomplished in terms of the Paleozoic sedimentary, stratigraphic sequence and palaeontological fauna of Gondwana and Yangtze continental margin, establishment of stratigraphic framework has been perfected. The results of Longmu Co-Shuanghu ophiolite suture zone study are really encouraging. The authors succeeded in identifying the Permian ophiolite, discovering a complete set of Early Paleozoic ophiolite and precise dating.
