摘要 八窝龙—玉农希断裂是四川九龙地区较大的一条断裂构造。通过野外对断裂构造变形、构造活动特征及地貌、地热进行调查研究,分析了断层卫星影像和地震资料,并对断层泥进行了测年。综合分析认为,八窝龙—玉农希断裂为发震的弱活动断裂,具分段性:其南西段(八窝龙断裂)在全新世具有弱活动性,北东段(玉农希断裂)在全新世表现为较强的活动性。 Study of structural deformation, geomorphic feature and geothermal activity in combination with satellite image, seismic data and selvage dating indicate that the Bawolung-Yulongxi fracture is a causative fracture and may be divided into weakly active SW sector (Bawolung faulO and strongly active NE sector (Yulongxi fault) in the Holocene.
