地球物理勘探,是地质勘查工作中的一门新技术、新方法。地质工作者一般是凭借观察地表的岩层露头取得原始资料的。为了了解地壳深处的情况,就不得不打很多钻井。地球物理勘棵,是用仅器来观测地下岩层的物理现象(如地磁、地电、重力加速度、地震波的传播等),再根据地球物理学的原理,间接地推断有益矿藏的存在,和指示地质构造的情况。尽管它不如钻探准确,最终还 Geophysical exploration is a new technique and method in geological exploration. Geologists generally obtain raw data by observing the outcrop of the earth’s surface. In order to understand the depth of the earth’s crust, a lot of drilling has to be done. Geophysical surveying is the use of only instruments to observe the physical phenomena of underground rock formations (such as geomagnetism, geoelectricity, acceleration of gravity, propagation of seismic waves, etc.), and indirectly inferring the existence of beneficial deposits and indications according to the principles of geophysics. Geological structure. Although it is not as accurate as drilling, it eventually
