众所周知,二十世纪后半期世界各国对矿产资源和能源的需求剧增,出露在地表或地表附近尚未开采的矿床越来越少,人们不得不去寻找埋藏深度越来越大的那些矿床。因此,现在地质学家面临的任务是,尽可能可靠而全面地获取某个矿物原料远景区,甚而整个地壳的深部地质构造资料。当然,以前所作的地质图由于只反映了地表或地表附近的构造,这种图就是再详细、再完善也解决不了这个任务。近十年来的科学技术革命,地质学中出 As we all know, the demand for mineral resources and energy in all countries in the world increased sharply in the latter half of the 20th century. Fewer and fewer unexposed mined areas are exposed on or near the earth’s surface, and people have to look for those deposits that have a greater and greater depth of burial. Therefore, the task now facing geologists is to obtain as reliable and comprehensive as possible the deep geological structure information of a prospect of mineral materials and even the entire crust. Of course, the previous geological map only reflects the structure of the earth’s surface or nearby surface. This figure is detailed and perfect. It can not solve this task either. Science and technology revolution in the past decade, geology in the out
