龙门山中北段遥感图像解译的新发现

NEW DISCOVERIES OF REMOTE SENSING IMAGE INTERPRETATION IN CENTRAL-NORTHERN SEGMENT OF LONGMENSHAN MOUNTAINS

对龙门山中北段,采用陆地卫星MSS和TM图像,进行数字图像处理和地质构造解译,共解译出断层35条,隐伏环形构造5个。新发现的茂汶断层北东段和擂东断层对龙门山构造带的进一步划分具有较大的意义;而吴家坪一桂溪U形断层则为唐王寨滑覆体的确定提供了有力的证据。推测武都等三个隐伏环形构造为有利的含油气构造。

Depending on digital image processing and geological interpretation, thirty five faults andfive buried circular structures have been interpreted from Landsat MSS images and TM images in cen-tral-northern section of Longmenshan Mountains. The paper points out that the new-discovered northeast section of Maowen Fault and LeidongFault are of importance in studying Longmenshan Mountain Tectonic Belt; that the new discovery ofU-shaped fault in Wujiaping-Guixi provides a significant evidence for determining Tangwangzhai Slid-ing Body; and that three of the five buried circular structures are advantageous oil-bearing or gas-bearing traps.
