本文着重阐述了华蓥山断裂带盖层构造的展布和组合特征及其受北东向深断裂的影响;根据钻井和人工地震勘探资料揭示了地腹构造的基本形态和分布规律及其与地表构造的关系;运用重力、磁力资料对四川盆地基底性质和结构作了必要的推测。从地质构造角度出发,结合历史地震和近期地震活动情况,对华蓥山深断裂带未来地震的可能性,分段进行了分析讨论,提出了南段具备发生中强地震的地质条件。
This paper focuses on the distribution and assemblage characteristics of the Huayingshan fault zone and their influence by the NE-trending deep faults. According to the data of drilling and man-made seismic exploration, the basic morphology and distribution of the terrestrial structure and its correlation with Surface structure of the relationship between the use of gravity and magnetic data on the nature and structure of the basement of the Sichuan Basin made the necessary speculation. From the perspective of geological structure, combined with historical earthquakes and recent seismic activity, the possibility and segmentation of future earthquakes in the deep fault zone of Huayingshan are analyzed and discussed. The geological conditions for the occurrence of moderate-strong earthquakes in the southern segment are proposed.
