Zhaoyuan-Pingdu fracture zone is one of the most important gold mineralization belt in northwestern Jiaodong area. Along the structure-mineralization belt, more than ten deposits in different sizes have been found now, which is represented by Linglong gold deposit. It is showed that there is good metallogenic conditions in this area. There are many types of structures and complicated alteration zones in Zhaoyuan-Pingdu fracture zone. Continuous stable fracture surfaces are well developed. Regarding main fractural surface as the center, altered rocks in the upper and lower walls are non-mirror symmetric distribution. It is significant to study non-mirror symmetric characteristics of altered rocks in Zhaoyuan-Pingdu fault belt.
