备注

讨论了昆明盆地中深层地震剖面的反射层标定、地震剖面的追踪对比、速度分析等资料解释工作,结果发现以前被多数人忽视的盘龙江断裂是控制昆明盆地形成、发展的一条重要断裂,昆明盆地不是典型的地嵌地垒型结构,而是西断东超的结构。

We introduce the reflecting layer calibration,reflector trace and velocity analysis for the reflection exploring in Kunming Basin,and give the result of data interpretation.The Panlongjiang fault is an important fault controlling the development of Kunming Basin but neglected by previous investigators,and Kunming Basin is faulting in the west and overlapping in the east,not the typical graben-horst style.
