华蓥山断裂带是四川盆地东界断裂带。前人认为该断裂带的最新活动时代为中更新世中期至晚更新世早期。作者近期野外调查发现了华蓥山断裂带晚第四纪走滑活动证据,位于华蓥山断裂带中段高县罗场镇兴场垇口村,称为兴场垇口断裂,该断裂长15km,走向NE30°,横切该区山体、造成多条水系扭曲,形成地表壮观的逆坡向右旋断错地貌。该断裂断错距今(14.86±1.26)ka地层,断裂的晚更新世晚期垂直活动速率为0.15mm/a,右旋走滑活动速率0.31mm/a,为晚更新世晚期右旋逆走滑活动断裂。
Huayingshan fault zone is the eastern boundary of Sichuan Basin. The former thought that the latest activity of the fault zone was from mid-late Pleistocene to early Pleistocene. Recent fieldwork has revealed evidence of Late Quaternary slip in the Huayingshan fault zone, located in Qiaokou Village, Xingchangchang, Luochang Town, Gaoxian County, the middle section of the Huayingshan fault zone and is known as Xingkoujioukou fault, which has a length of 15km , To NE30 °, cross the mountain body, resulting in a number of twisted water system, the formation of the spectacular surface of the reverse slope to the right turn off the wrong landscape. The late fault interval (14.86 ± 1.26) ka and the late Late Pleistocene vertical activity rate are 0.15mm / a and the right-lateral strike slip rate is 0.31mm / a, which is the result of the late-Late Pleistocene inverse strike-slip Breaking activity.
