| Abstract: | The porphyry belt in Ninglang area is important part of the Xishan tectonic-porphyry metallogenic belt of the tectonic active belt in the western edge of Yangzi Based on the study of petrochemical characteristics of the porphyry bodies in the belt,it can be concluded that the mag-metic material originated from mantle and mixed-source model of crust-mantle accompanied with continental crust. The porphyry bodies are copper-bearing or copper-molybdenum porphyry.There are good metallogenic conditions and prospect in the belt. |
