| Abstract: | The metallogenic belt in Central Yunnan Province shows multi-scale geological anomaly controlled by multi-grade structural system. The south-north tectonic belt of China controlled this metallogenic belt as regional geological anomaly. Extensional structural system, thrust and nappe systems and shear structural system controlled local geological anomaly. Detachment faults, thrust faults and brittle-ductile shear zones controlled small-scale geological anomaly, and joints, fissures, mylonite foliations, structural schists, and fault rocks controlled micro-geological anomaly. The internal relations between structures and ore deposits in Central Yunnan Province indicate that the ore deposits were formed by tectono-reworking metallization. |
