|dc.description.abstract||Geoelectric surveys at 461 VES locations were carry out in the area of the coastal plain between Peikangchi and Erhienchi, southwestern Taiwan. The sounding data were interpreted by using 1-D inversion method. The electrostratigraphy in the study area can be obtained.
Based on the resistivity and thickness of the layers derived from the sounding data, three electrostratigraphic units are being recognized. From the ground surface to a depth of 200 m, the strata were named the T, S, and R facies. The resistivity of T-facies is ranging from 10 to 50 ohm-m with a thickness of 1 to 90 m. It locates in the center and east of the study area and associated with the terrestrial, estuarine and lagoonal environments. The resistivity of S-facies is less than 8 ohm-m. it has a thickness ranged from 35 to 120 m or more. Most of S-facies are overlaid by the T-facies in the western part. It may associate with a marine environment. The resistivity of R-facies is ranging from 3 to 90 ohm-m. It is overlaid by the T-facies in the eastern part and by the S-facies in the western part of the study area. In the southern part of the study area (between Yanshuichi and Erhjenchi), the S-facies and R-facies may merge together in a great depth. But we can’t prove it by a limited depth penetrating of this survey. The R-facies may deposite in the terrestrial and estuarine environments.
Based on the dating results obtained from well samples, the T and R-facies were deposited in Holocene, and the R-facies was deposited in late Pleistocene. The boundry between R and T-facies or R and S-facies may associate with geological boundary between late Pleistocene and Holocene. The depth of the boundary is ranging from 10 to 130 m below the sea level, it has a trend of increase the depth from northeastern to southwestern. However, the boundary between Yanshuichi and Erhjenchi is still uncertainty from our data.||en_US|
