| Abstract: | In the middle of December, 1992 , we have made three MTS measurement sites in the region of Great Wall Station,Fildes Peninsula,West Antarctica. Throughout the survey,we uesd the Magnetotelluric Measurement Station MMS 02 system. This paper deals with the results of the MT observations and pointed out that the electrical conductivity major axis of
Wind Valley Fault is around 110°NE and the thickness of the crust in the Fildes Peninsula is
about 22. 3km. The crust includes four main electrical condutivity layers and the thickness is 1. 3km, 6. 7km, 1. 2km,and 13. 1km respectively. The upper crust is 9. 2km and lower crust is 13. 1km. |
