| 摘 要： | 新疆塔中地区奥陶系分布广泛。主要根据化石、岩性特征、对比等将研究区内奥陶系划分为三统四组:下奥陶统蓬莱坝组与下伏上寒武统丘里塔格下亚群呈假整合接触,鹰山组归为中下奥陶统,一间房组划为中奥陶统,良里塔格组划归上奥陶统。良里塔格组可细分为3个岩性段,鹰山组可划分为4个岩性段。良里塔格组与鹰山组之间存在区域地层缺失和不整合,桑塔木组与上覆地层呈不整合接触,与下伏良里塔格组由于所处的位置不同呈整合或不整合接触。

| Abstract: | Ordovician strata are widely distributed in the Tazhong Area. The goal of study is to identify the Cambrian-Ordovician boundary in this area and to determine the age and lithostratigraphic relationship among the Yingshan, Yijianfang, and Lianglitage formations, on the basis of biostratigraphic and lithostratigraphic evidence. Research results are as follows:1) The Yingshan Formation is regarded as Lower-Middle Ordovician, the Yijianfang Formation as Middle Ordovician, and the Lianglitage Formation as Upper ... |
