摘要
本文通过对潍坊滨海区1/5万高精度重力数据的处理,提取出研究区地质构造的重力异常信息,结合地质资料分析得出:研究区布格重力异常宏观形态为"两高两低",划分出断裂构造9条;通过重力数据三维反演,对研究区内两个Ⅳ级构造单元边界和五个Ⅴ级构造单元进行了精细厘定,为研究该区区域地壳稳定性、地质灾害发育特征和深部物质的均衡状态等提供基础资料。
The extraction of gravity anomaly information of geological structure from 1/50 000 high- precision gravity processing in the littoral region of Weifang,Shandong province,combining with geological data analysis, the Bouguer gravity anomaly presents“two high areas and two low areas”from macroscopic view in study area, and delimitates 9 faults. And the 3-D inversion was utilized to accurately revision two IV-level structural unites and five V-level structural unites. These results provide the basic data for the study of regional crustal stability, the development characteristics of geological hazard and deep substances equilibrium in the study area.
