摘要
Based on the airborne gravimetric data of the first-time experimentation in China, passing through the emphasized processing and inverse simulation of local gravity anomalies and combining with the aeromagnetic, seismic and drilling data, according to the character of the geological body which cause the local anomaly, six types of local gravity anomalies are divided in this research area, which are associated respectively with basement salients, basement sags, intrusive rocks, volcanic rocks, old strata within intermediate-acid magmatic rocks and mantle plume in deep place, etc. Every type of local gravity anomalies can also be divided into some kinds of local anomalies according to the geological attribute, which can be the reflection of certain mineral resources.
