摘要
There are a kind of important Fe-Cu-Pb-Zn multimetallic deposits in Deqin-Weixi area of NW Yunnan Province. The ore-bearing beds are a suite of sedimentary rocks with intercalations of intermediate acid-basic volcanic rocks. In the present geological references,the viewpoints on the geochronology and nomenclature of them are very confused. According to the study, the authors think they must belong to Middle Triassic Pantiange Formation, Middle-Upper Triassic Cuiyibi Formation. And the authors suggest that Waigucun Formation, Sanhedong Formation, Waluba Formation and Maichuqing Formation can be regarded as the name of Upper T in Mesozoic, Cenozoic superimposed inland basin of Lanping-Simao, whereas Pantiange Formation, Cuiyibi Formation, Shizhongshan Formation as the name of T of Weixi epicontinental arc zone of Jinshajiang tectonic system for the convenient stratigraphic correlation of T between 2 different tectonic units.
