| 摘 要： | 川滇南北向构造带是中国西南地区最重要的构造－成矿带之一，产铜、铁、铅锌、磷、镍、金、银、钨锡、碲等多种矿产。该构造带的构造演化可分为前震旦纪的板块成型期和早震旦世的后造山期、晚震旦世－早新生代的板内稳定－破裂－造山期和晚新生代的后造山期，即本区陆壳在早元古代形成后曾两开两合，并在其不同时期控制了不同矿床形成。

| Abstract: | The Sichuan Yunnan meridional structural belt is one of the most important structural and mineralized belts in the southwest China. Twice opening closing cycles took place in the belt, the first is the rift orogenesis cycle in Presinian and the epiorogenic period in the early Sinian, the second is the rift orogenesis cycle from late Sinian to Eogene and the epiorogenic period from Neogene to Quaternary. Deposits of Cu, Fe, Pb, Zn, P, Ni, Au, Ag, W, Sn, Te, REE etc. were formed in different period. |
