The Guocheng-Yazi area in the northeastern margin of the Jiaolai Basin is located in the southern section of the Muping-Rushan gold metallogenic belt. It is an important gold metallogenic area in the Jiaodong region. In recent years, medium-sized and large-scale gold deposits such as Pengjiakuang, Tudui-Shawang, Xijingkou, Liaoshang, Xilaokou, and Qianchuiliu have been successively explored. The cumulative amount of gold resources explored exceeds 180 t. Based on the field work of geological mapping, ore-bearing structure investigation, controlled source audio-frequency magnetotelluric sounding (CSAMT) and drilling engineering, the distribution of ore bodies, geophysical characteristics, ore-controlling structure and metallogenic regularity were analyzd. The western extension position of the Pengjiakuang detachment fault was preliminarily clarified. Extending westward from the Xijingkou to the Liaoshang to the Guocheng fault, which is the ore-controlling structure of Pengjiakuang, Xijingkou, Xilaokou, Qianchuiliu, Liaoshang and other gold deposits. The Queshan metamorphic core complex and its detachment faults are the main ore-controlling structures and favorable ore-forming spaces for gold mineralization in this area, and are important prospecting targets in future exploration and prospecting work. The mineralization depth of the gold deposit concentration area in this area is mainly 5.01~7.93 km, and the gold deposit has just been eroded as a whole. The deep and peripheral areas have good prospecting potential.
