| 摘 要： | 区内中—下三叠统隆务河群（T1-2L）属巨厚复理石相，显示出以浊流为主的深海沉积特征；通过沉积相分析，整个隆务河群由下而上呈一个明显的变细、变薄的序列，呈一个较完整的海底扇退积型沉积序列。

| Abstract: | Widely distributed Lower-Middle Triassic Longwuhe group (T1-2L) in the western section of the West Qin Ling Mountains is of a thick flysch facies, showing a feature of dominant turbidity in a deep sea setting. Analysis of this sedimentary facies reveals that the whole Longwuhe Group is a sequence that becomes finer and thinner from lower to upper, a relatively complete retrograding submarine fan sedimentary sequence. |
