摘要
Based on geological surveys and researches, the study discussed four typical deposits distributed on the western Bangonghu-Nujiang metallogenic belt, and their C, Si, O, S and Pb isotope characteristics. It can be concluded that the metallogenic mode of the western section of the Banggonghu-Nujiang metallogenic belt is that the skarn-type orebodies formed along the exocontact zone between Early Cretaceous magmatic fluid and Permian, Triassic and Cretaceous marine carbonatic rocks, and the porphyry-type orebodies formed along the endocontact and exocontact zones between the magmatic fluid and Mid-Jurassic and Lower Cretaceous sandstone and siltstone.
