摘　　要：随着依兰—依通断裂中支全新世活动性证据的发现,引起了越来越多学者对该断层的关注,但对与之相距仅几十公里的东支断层却研究甚少。通过依兰煤矿的深部地震资料,初步确定了该东支断层的地表投影位置;而后,布设了两条浅层人工地震反射勘探测线,以识别东支断裂的近地表构造,为对该地区的进一步研究提供基本资料。With the Holocene activity evidence of. middle branch of Yilan-Yitong Fault, more and more scholars pay attention to the fault. But there is very little research on the East branch of the fault which is a few tens of kilo- meters away from the West branch. In this work, we preliminary determine the projection position of East branch of the fault on surface by deep seismic data of Yilan coal mine. Then we laid out two artificial reflection seismic explo- ration lines in order to identify the near surface structure of East branch, which can provide basic data for the following research in the area.
