摘要
Abstract
There are different opinions about the Permian/Triassic boundary and its correlation in the Daxian- Xuanhan area because of lacking typical lithological symbols and fossil criterions. Especially,it is very hard to determine the Permian/Triassic boundary in the Daxian-Xuanhan buried areas. This brings many difficulties to geological research and oil and gas exploration. Based on field investigation and studies of well cores, newly found fossils, lithological characteristics and well log analyses, the authors discussed the Permian/Triassic boundary in the Daxian-Xuanhan area and brought forward a specific scheme for its determination and regional correlation.关键词
