| 摘 要： | 本文涉及的张家界温塘志留系实测剖面位于武陵隆起(属雪峰山隆起)以西。在志留纪之前,张家界东南侧雪峰山局部地区已经隆起成陆。在志留纪期间,随着隆起范围的扩大,对沉积环境产生重要的影响,使其从浅海逐渐向滨岸过渡。在晚志留纪末可能陆地范围扩大至慈利-保靖以西。该区志留系剖面的沉积序列和沉积岩相的演化与武陵隆起的演化过程存在明显的耦合关系。在剖面上缺失上志留统-中下泥盆统地层沉积纪录。

| Abstract: | The measured Wentang Silurician section in Zhangjiajie lies in the area west of the Wuling uplift in Hunan. Prior to the Silurician, the Xuefengshan area was once uplifted and graded into the land. The expansion of the Xuefengshan uplift during the Silurician led to the transition of the study area from shallow marine to littoral environments, and even to the land in the area west of the Cili-Baojing zone till the end of the Late Silurician. The evolution of sedimentary sequences and sedimentary facies indicated by the Wentang Silurician section in this area noticeably displays the coupling relationship with the evolution of the Wuling uplift. The Upper Silurician-Lower and Middle Devonician stratigraphic records are absent in the measured section. |
