摘    要:皖南歙县、休宁一带晚震旦世下部兰田组上段钙硅质岩中发现碎屑流引起的滑塌砾岩层,上部皮园村组硅质岩中发现浊积岩夹层及风暴流沉积层,表明皖南地区晚震旦世应为半深海-浅海环境,而非通常所说的深海环境.

关 键 词:滑塌砾岩层    硅质风暴岩    皮园村组    兰田组    晚震旦世    皖南地区

Abstract:We have found in Shexian and Xiuning Counties of South Anhui that ther e are some turbidite interlayers and a debris flow caused olistostrome near the to p of the Lantian Formation of the lower member of the Upper Sinian, and t here are some siliceous storm sediments in the Piyuangcun Formation of the top m ember of the Upper Sinian.These discoveries indicate that the area of South Anh u i belongs to a hemipelagic or shallow environment when sedimentation occurs duri ng the late Sinian,not a pelagic environment as being usually believed ,at lea st the sedimentary surface was not lower than the wave base of the storm.
Keywords:olistostrome    storm sediments    Piyuancun and Lantian Formati ons    Late Sinian    South Anhui
