西天山阿沙勒河中上游二叠系的发现及环境分析

Discovery of Permian Strata along Middle-upper Reaches of Ashale River and Its Environment Analysis, Western Tianshan

近年在西天山阿沙勒河中上游的博罗霍洛山地层小区新发现陆相二叠系,分布面积较大,其岩石组合及岩相特征与区域上的中下二叠统乌郎组相同,并采获二叠纪孢粉化石,这是该地区二叠纪地层古生物工作取得的新进展,具有重要的研究意义。

During recent years, the continental Permian was discovered along the middle -upper reaches of Ashale River which belong to the small area of Boluohuoluo Mountain, Western Tianshan. The Permian area is in distribution widespread, its characteristic of the rock combination and the lithofacies is identical with Middle -Lower Permian Wulang Formation on the district, and the Permian sporomorph fossils were obtained by authors. This is a new progress about the strata and the ancient organism of the Permian in the region. It is possessed of momentous implication of researching.
