提出运用剥蚀量恢复技术进行构造圈闭的形成与演化研究,即通过对与构造圈闭形成密切相关的几次构造抬升所形成的不整合面进行剥蚀量恢复,可以了解不同地史时期构造圈闭的分布情况,分析它们的形成与演化过程。以川西坳陷中段为例,通过应用不同技术分别对研究区3个关键不整合面进行剥蚀量恢复,恢复结果表明,川西坳陷中段孝泉构造—新场构造—合兴场构造、大邑构造形成于安县运动;晚印支运动期鸭子河构造、马井构造形成,洛带构造开始形成;喜马拉雅运动使研究区先存构造再次强烈隆升,并催生了石泉场构造和丰谷构造。依据圈闭条件和保存条件将它们划分为4种类型。
It is put forward that the research on the formation and evolution of structural traps by means of denudation recovery technique is based on the restoration of the denudation volume of the unconformity caused by several tectonic uplift that is closely related to the formation of structural traps. Closed distribution, analysis of their formation and evolution process. Taking the middle section of western Sichuan Depression as an example, the denudation recovery of the three key unconformities in the study area was studied using different techniques. The recovery results show that the middle Xiaoquan structure - new field structure - Hexing formation structure, Dayi The structure was formed in the Anxian movement. During the Late Indosinian movement, Duzihe structure, Majing structure and Luodai structure began to form. The Himalayan movement strongly uplifted the preexisting structure of the study area and gave birth to the Shiquan field structure and Fenggu structure. They are divided into four types based on trapping and preservation conditions.
