主　　题：Magnetotellurics Two-dimensional inversion Structure Shenzhen fault zone 

摘      要：The magnetotelluric sounding method was used to study the active fault in Shenzhen *** magnetotelluric profiles with a dense station interval were laid out across the Shenzhen fault *** remote reference technique was used in both data observation and processing to eliminate the electromagnetic noise near the survey sites,and relatively smooth apparent resistivity curves were *** mode data and two-dimensional inversion method as NLCG were used to obtain the electrical structures *** to the surficial geology survey results on regional strata and distribution of magmatic bodies and faults,the electrical structures at depths less than 2000m of each profile were *** regional faults,the Henggang-Luohu fault and the Liantang fault,and seven local faults consistent with the electrical boundaries were verified or *** strata in the survey area were then related with the change of *** horizontal slices of depths less than 5000m indicate that the Henggang-Luohu fault and the Liantang fault bifurcate at the shallow part but tend to merge in the deep part.
