Abstract: The Xinjiazui gold deposit in Qin-ling area is located in the west of Mianluoning Golden Triangle in Hanzhong, Shaanxi Province, This gold deposit has great metallogenic potential. However, Carbon-bearing strata are widely distributed in the area, the traditional geophysical and geochemical exploration methods are interfered to some extent. In this paper, through the application of integrated electrical exploration such as audio magneto-telluric sounding (AMT) and induced polarization（IP） method, the deep morphological characteristics of ore-controlling fault in Xinjiazu gold deposit are identified, the combination of deep prospecting prediction technology and method for gold deposits in carbon-bearing strata is explored, the metallogenic mechanism is discussed and the ore deposit markers are summarized. Comprehensive electrical exploration can obtain the deep electrical structure characteristics of the study area, so as to locate and predict the deep occurrence location of gold deposits under the interference of carboniferous rock series and form the ore deposit markers. New discoveries of regional prospecting have been obtained through the deep engineering verification, and the metallogenic mechanism of the study area is proposed.
