摘要
皖南东至地区晋宁运动，早期为一近 ＮＷ向线型紧闭同斜倒转褶皱，晚期为 ＮＷ到近ＳＮ向 同斜倒转褶皱，末期为 ＮＥ到ＮＥＥ向开阔褶皱，并出现了较为复杂的叠加褶皱。区内存在两个重要不整 合面，并将中、新元古代地层分割成三个构造层。
The Jinning Movement in the Dongzhi area of South Anhui is expressed as a substantially EW - trending linear tight isoclinal overturn fold in its early period, NW - to SN - trending isoclinal overturn fold in its late period and NE - to NEE - trending open fold with occurrence of complicated superposition of folds in the end. The field evidences indicate the presense of two significant dis continuities that delimited three tectonic strata of the mid - late Proterozoic era.
