重力勘探和磁法勘探一样,也是研究地面上的物理場。但它是以研究地壳的岩层所引起的重力場为基础,来说明工作地区的地质构造和矿体分市及其特征的。重力勘探的决定因素是下伏岩层与上复岩层之間,或者矿体与围岩之間存在的密度差。只要密度差有足够大,地形又不是十分复杂的地区,重力勘探都是适用的。由于异常的不同分布情况可 Gravity exploration, like magnetic exploration, is also a study of the physical field on the ground. However, it is based on the gravitational field induced by the study of the crust of the earth’s crust to illustrate the geologic structure and ore-body breakdown of the work area and its characteristics. The determining factor for gravity exploration is the difference in density between the underlying rock and the overlying rock or between the ore body and the surrounding rock. As long as the density difference is large enough and the terrain is not very complicated, gravity exploration is applicable. Due to the different distribution of abnormalities can be
