川西义敦地区波格西上二叠统剖面最早测制于1974年1:100万区调填图。1985年,1:5 万义敦幅区调填图时又重新测制。1989年7月,成都地矿所和四川省地矿局区调队共同协作再次对该剖面进行有关沉积相方面的研究。本文就是这次研究工作成果的一部分。
The first section of the Upper Permian in the Pugxi area of Yishun in western Sichuan Province was first surveyed in the area of 1: 100 million in 1974. In 1985, 1: 50000 Yishun District transferred map again when the re-measurement. In July 1989, the Chengdu Institute of Geology and Mineral Resources and the Geological and Geological Survey of Sichuan Bureau of Geology and Mineral Resources worked together again to conduct a study on the sedimentary facies of the profile. This article is part of the research effort.
