Jiaodong Peninsula is the most important and largest concentration region of gold deposits in China.Recent studies show that gold deposits in Jiaodong area are closely related to craton destruction in the North China.Metallogenic and diagenetic age initially suggested that Guojialing granite is the  geological body of gold mineralization in northwest Jiaodong area.Despite the mineralization age of Dayingezhuang and Xiadian gold deposit certify a directly relationgship to the early Cretaceous Guojialing granite，there is no emersion of Guojialing granite in south Zhaoyuan.Linear and annular structures are obtained by remote sensing interpretation，and the possible location of concealed rock mass is delineated by comprehensive exploration using aeromagnetic method，Eh-4 coutinuous resistivity imaging system and CG-5 relative gravimeter.The measurement results indicate that Guojialing granite magnetic anomaly is not obvious，it invades in concealed rock dendritic with medium-high resistivity（1 000~3 000 Ω·m） and lower relative gravity anomaly（<8 mGal），and the buried depth is about 1 km.The altered fracture zone associated with mineralization is an electrical body with low resistivity（0~1 000 Ω·m），and distinguished from other geological bodies.The combined application of a variety of geophysical exploration methods has a good effect on locating concealed intrusions and identifying altered fracture zones.
