| 摘 要： | 郯庐断裂是华北板内重要变形，也是华北煤田重要控煤构造，它将华北晚古生代聚煤盆地东段切割推移，使之成为相对独立的构造单元；控制了华北板内变形：断裂旁侧派生的旋卷构造，构成新颖的煤田构造样式。从华北晚古生代聚煤盆地沉积和变形的视角看，郯庐断裂中生代走滑平移，估算最大水平位移量达５００ｋｍ，东盘辽吉块体岩壳消减量２５０ｋｍ，走滑运动时限，从印支期始，燕山晚期走滑速度增快达到高潮，并向伸展运动转化。

| Abstract: | Tanlu fault is an important distortion in the North China Plate,and it is an importantcoal-control structure in North China coal field too. It divided and shifted the east part of theNorth-China's Palaeozoic coal-accumulation basin,and made it become an independent struc-ture unit;it resulted in the formation of vortex structure beside the fault, and formed a newcoalfield structure pattern.This paper stated the feature of strike-slip shift of Tanlu fault in Mesozoic. It was esti-mated that the most shift is about 500 km: its rockcrust subducted in the east side Liao-ji block is about 250 km. The strike-slip shift began from Indo-Sinian,in Yanshanian attained its shifting peak,and later it evolved to stretch nature. |
