| 摘 要： | 详细的沉积相分析表明，皖南蓝田盆地上震旦统蓝田组由局限台地相、陆棚相和陆棚边缘盆地相组成。以Ｍｏ／Ｍｎ和Ｖ／（Ｖ＋Ｎｉ）比率相结合作为氧化还原环境指标，确认缺氧还原环境是蓝田组的重要特征之一。以Ｃｌ含量和Ｓｒ／Ｂａ比率相结合作为古盐度指标，蓝田组有两个高盐度期。蓝田组沉积环境演化旋回性明显，由两个完整的旋回组成。

| Abstract: | Detailed analysis of depositional facies shows that Lantian Formation(LF) in Lantian Basin in South of Anhui Province is composed of limited platform, shelf and marginal basin of shelf.With Mo/Mn ratio combining with V/(V+Ni) ratio as an indicator of redox environment,a strongly anoxic environment is determined as one of the important features in LF.With concentration of Cl combining with Sr/Ba ratio as an indicator of paleo salinity,LF has two high salinity stages .Evolution of depositional environment of LF includes two entire cycles. |
