摘要:
嵩山地区的三叠系主要分布在登封县大金店、东金店及芦店等地,为一套紫红—灰绿色内陆河流—湖泊相碎屑岩沉积,总厚度达1203～1640m,其中产丰富的动物和植物化石。该系与下伏二叠系石千峰组呈整合关系,其上部被第三系所不整合覆盖。根据岩性特征、生物组合及区域地层对比,将本区三叠系划分为:下三叠统刘家沟组、和尚沟组,中三叠统二马营组、油房庄组,上三叠统椿树腰组和谭庄组。
Abstract:
The Triassic in the Mount Songshan area is mainly distributed in Dajindian, Dongjindian and Lud.ian.It is represented by a sequence of purplish red to greyish green inland fluvial-lacustrine clastic rocks, with a total depositional thickneess up to 1203—1640 m, yielding abundant animal and plant fossils. This system displays conformable contacts with the underlying Permian Shiqianfeng Formation and is unconformably by the Tertiary. According to the lithologic features, biological assemblages and regional correlation, the Triassic of the area may be divided into the Lower Triassic Liujiagou Formation and Heshanggou Formation, the Middle Triassic Ermaying Formation and Youfangzhuang Formation and the Upper Triassic Chunshuyao Formation and Tanzhuang Formation.
