| 摘 要： | 描述了东秦岭山地铁炉子断裂新活动的方式、表现以及断裂所在地区的新构造应力场。从河流阶地所反映的断裂在水平方向和垂直方向上的错距和错动速率看 ,铁炉子断裂的新活动主要表现为左旋走滑活动 ,其水平活动规模比垂直活动大一个数量级 ;该断裂垂直活动比较明显的地方是沿盆地发育的地段 ;断裂活动有加速的趋势。铁炉子断裂的新活动方式很可能是由于印度板块向北碰撞挤入欧亚板块及由此造成青藏高原隆起 ,使中国东部地块向东或东南方向差异性滑移的结果 |

| Abstract: | This paper describes the pattern and appearance of the recent activity of the Tieluzi Fault and recent stress field in East Qinling Mountains. The recent movement of the Tieluzi Fault has resulted in the "S"-shaped turning of streams, displacement of terraces and Neogene sediments along the fault. The recent stress field over the East Qinling Mountains was dominated by SEE-trending compressive stress. The amplitude and rate of faulting were determined on the basis of the differences of elevation, lateral di |
