| 摘 要： | 滇西北德钦—维西一带有一类重要的铁铜铅锌多金属矿,含矿岩石为一套夹中酸性—基性火山岩的沉积岩系。目前的地质文献中,该沉积岩系的时代和名称争论颇多。笔者研究后认为应是中三叠统攀天阁组、中—上三叠统崔衣比组。建议以巍山地区歪古村组、三合洞组、挖鲁八组及麦初箐组作为兰坪—思茅中、新生代上叠陆内盆地的上三叠统地层名称;而攀天阁组、崔衣比组及石钟山组则为金沙江构造带维西陆缘弧带的三叠系地层名称,便于两个不同大地构造单元三叠系地层的对比。

| Abstract: | There are a kind of important Fe-Cu-Pb-Zn multimetallic deposits in Deqin-Weixi area of NW Yunnan.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,we think they must belong to Middle Triassic Pantiange Formation,Middle-Upper Triassic Cuiyibi Formation.And we 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. |
