摘要
云南巧家-石屏盆地早震旦世的充填序列可划分为下段冲积扇-大陆人山-砾质辫状河沉积,中段曲流河沉积及上段砂质辨状河沉积。盆地经历了早期断陷、中期拗陷及晚期萎缩回升3个构造演化阶段。
The sequences of filling of Qiaojia-Shiping basin of Yunnan during EarlySinian can be divided into alluvial fan-continental volcanies-pebbly braided river deposits inthe lower part, meandering river deposits in the middle part and sandy braided river depositsin the upper part. This basin underwent three evolution stages, i. e, early faultdepression, middle down-warp and late contraction and uprising.
