ANALYSIS ON GRAVITY ANOMLIES AROUND RENQIU-BAOTANGCANGZHOU AREA

In this paper, the quasi-stationary adjustment treatent, ground water correction and ground deformation correction of the data of repeated gravity measurements around Renqiu-Baotang-Cangzhou area are made. Then the variation of gravity field appeared since 1986 is discussed. The results show that around this area exists a high value anomaly of +60~+80×10^-8 m/s². It can be inferred that this anomaly is mainly caused by deep variations. Therefore, it is necessary to pay attentionto it.
