| 摘 要： | 皖南地区在晚震旦世早期早时发生海侵，沉积了含碳、含硅的陆源碎屑岩，为浅海盆地相沉积；早期晚时，沉积了碳酸盐岩和碳酸盐岩夹粘土岩沉积，为台坡和台盆相沉积，其沉积相变化和古地理分异与当时基底性质、同沉积构造和碳酸盐建隆作用密切相关。

| Abstract: | In the beginning of the early period of late Sinian marine transgression took place in South Anhui, and carbon - and silicon -bearing terrestrial clastic rock deposited there, i. e. shallow sea basin facies. In the late of the early period , carbonate rock and carbonaterock intercalated with clay rock deposited, i. e. Platform - slope facies and platform - basin facies, whose change of depositional facies andpaleogeographic differentiation were closely related to the nature of basement, syndepositional structure and carbonate buildup. |
