Abstract

Abstract: Gravity inversion is one of the most important techniques by which underground geological information is obtained. With density and electrical parameters statistical result in Tianjin, distributional characteristics of physical property of strata are studied in this paper. Using the technique of normalized vertical derivative of the total horizontal derivative of the bouguer gravity anomaly in Tianjin, this paper infers the faults structure and divides into tectonic units in Tianjin. Then the author carried out the inversion of density interfaces inside every tectonic unit in combination with geological information by the density interface inversion module in Geosoft software, and constructed 3-D visual geological models with the inversion results based on the software of GOCAD. In addition, calibrating of the main geological interface and structure was realized by means of virtual drill which is made by depth-apparent resistivity calculated by MT profiles. And the model reliability was verified by the geological profile fitted by Burguer gravity anomaly in the same position. By using the inversion results and previous geological understanding in this area, we inferred Baodi fault、Jiyunhe fault、F₃ fault、Yangliuqing fault and F₇ fault have strong activity after the Mesozoic era, and so are Cangdong fault and Tianjin fault after Paleogene.

Key words: gravity inversion, NVDR-THDR, fault identification, virtual drill, 3-Dimensional visualization modeling based on GOCAD, Tianjin
