Shihongtan area is located at the southwest edge of Toksun, Turpan, Xinjiang. In order to clearly divide strata and identify structures, the authors conducted 3-component fixed loop survey in this area. Fixed loop configuration can obviously raise work efficiency compared with moving loop configuration. The authors managed to measure 3 km survey line by settling a 500 by 500 meter transmitter loop. By modeling such 3-component data, the result could achieve better solution in both dividing strata and identifying structures than apparent-resistivity profile. The results achieved by the authors are also meaningful to the explanation and geological modeling.
