Abstract: Electric field sounding is a new technique for electric prospecting by means of high power and artificial field source shot with high resolution and accuracy. Its profile can be applied to clear reflection of the Carboniferous structures in LuDONG area in Junggar basin. There exist two sets of volcanic sequences in upper and lower parts of the Upper Carboniferous, sedimentary stratum in the middle. The lateral variation of lithology within the volcanic sequences and the development of their volcanic structures are also reflected in it. The study shows that in different areas the Carboniferous is in different degrees of remains which cause that obvious differences occur in corresponding electric structure of volcanic rocks. It is suggested that the electric field sounding technique as an important supplement process is of good applicable results for the Carboniferous explorative domain in North Xinjiang.

Key words: Junggar basin, LuDONG area, field sounding, Carboniferous, volcanic rock
