重力勘探是地球物理勘探方法的一种形式,其基础是在地表上研究重力场的性质。在组成地壳研究地段的岩石质量的作用下,就产生重力场的地方非均匀性。岩石这种东西具有各种不同的密度,并且构成式样纷繁的地质构造,因此会发生表征地球重力场的量值的异常,也就是与正常值的偏差,如果我们假定地壳是均质的或者由不同密度的均质同心层所组成,那末就该观测到这种正常值。在重力勘探中,作为直接
Gravity exploration is a form of geophysical exploration that is based on the study of the nature of the gravitational field at the surface. The local heterogeneity of the gravitational field is created by the rock mass that forms the crust’s study site. Rocks of various densities and geodesic structures make the magnitude of the Earth’s gravitational field anomalies, ie, deviations from normal, if we assume that the crust is homogeneous or consists of Different density of homogeneous concentric layers, then we should observe this normal value. In gravity exploration, as direct
