省内泥盆系发育程度较低。主要分布于北纬36°以北,南部见于玉树、西倾山。本文试图以型相系统为出发点对其进行归纳。据沉积类型、岩相、生物群特征将泥盆系划分为祁连山型,祁漫塔格型,西倾山型(图)。本文主要依据省第一区调队,省地研所,新疆、甘肃区调队所获实际资料。胡永元工程师审阅,唐翠梅绘制插图,谨致谢忱。 Devonian in the province a lower degree of development. Mainly located in the north latitude 36 ° north, seen in the southern Yushu, West Pijiangshan. This paper attempts to phase type system as a starting point for its induction. According to sedimentary types, lithofacies and characteristics of biota, the Devonian can be divided into Qilian type, Qimantag type and West Piedmont type (Fig. This article is mainly based on provincial first district transfer team, Provincial Institute, Xinjiang, Gansu transfer team received the actual data.
