【摘要】 介绍了利用GRISYS处理软件,对昆明盆地基底断裂反射地震勘探数据进行处理,得到测线的水平叠加剖面和偏移剖面的过程。处理结果显示,昆明盆地内松散沉积存在"西断东超"现象,而不是原来所认为的典型的地嵌地垒型;西山—普渡河断裂和盘龙江断裂是控制昆明盆地发育的主要断裂。更多还原

【Abstract】 We introduce data processing methods and procedures to explore the base faulting in the Kunming basin of Yunnan,using the GRYSIS software.Based on the reflection data,we obtain a horizontal stack profile and a migration profile respectively.The results show that the structure features of the Kunming basin are faulting in the west and overlapping in the east,not the typical graben and horst style as suggested by the previous investigators.The Xishan-Puduhe fault and the Panlongjiang fault are the major faults controlling the development of the Kunming basin.更多还原
