航空地质方法在地质测绘中是一种有效手段。尤其适用于地形、地质等条件困难地区。近两年来,铁二院在××线方案研究工作中普及和推广航空地质方面做了一些工作,有些初步体会。一、地质概况××线,全长1676公里。所经地形由于经历长期强烈和复杂的构造运动,造成地层复杂,褶皱和断裂多,规模大,岩性破碎,不良 Aviation geology method is an effective method in geological mapping. Especially for topography, geology and other conditions difficult areas. In the past two years, some efforts have been made to popularize and popularize aeronautics and geology in the research on the program of the XX Line, and some preliminary experiences have been made. First, the geological profile × × line, a total length of 1676 km. Due to the long-term strong and complicated tectonic movement, the terrain has complicated strata, large folds and faults, large scale, broken lithology and poor
