| 摘 要： | 六棱山北麓断裂位于阳原盆地南缘，是一条总体走向北东东，倾向北北西的倾滑正断裂。它的断错地貌在河北阳原独山堡发育最好且保存完整在，在狡山堡六棱山北麓断层陡坎前缘开挖了２个探槽，共揭示了２次古地震事件；采集了多个测年样品，经红外释光（ＩＲＳＬ）测年技术测定，初步获得了２次古地震事件发生的可能时代。

Study on the Paleoearthquake Chronology of the Northern Piedmont Fault of the Liulengshan Range of Yangyuan,Hebei Province,China |

| Abstract: | The northern piedmont fault of the Liulengshan Range lies along the southern edge of Yangyuan basin.It is a dip slip normal fault,NEE trending and NNW dipping.The offset geomorphology near Dushanpu is the best.Two trenches across the fault scarp of the northern piedmont fault of the Liulengshan Range near Dushanpu exposure two paleoearthquakes.Many proper samples for dating of the two paleoearthquakes were collected.Based on IRSL dating,age estimates of the two paleoearthquakes have been obtained. |
