Division of Buried Late Quaternary Strata of the Fuzhou Basin
Division of Buried Late Quaternary Strata of the Fuzhou Basin
摘要
Abstract
Based on detailed logging of fourteen drill holes, combined with the results of other researchers, the preliminary summarization on sedimentary characteristics of the late Pleistocene of the Fuzhou basin is done. The deposition of Fuzhou basin began from about 56.5ka BP and the sediments are composed of gravel, sand, clay and silt, which show a depositional sequence with granularity becoming smaller from the lower to the upper and a big lateral variation of lithology. There are three silt layers in late Quaternary strata of Fuzhou basin. The first and second layers were developed during the middle and late Holocene, the deposition time is about 7.86ka BP to 1.44 ka BP and they are the results of "Changle Transgression". The third was developed during the late of late Pleistocene and the deposition time is from 44ka BP to 20ka BP and it is the result of "Fuzhou Transgression".The buried late Quaternary sediments in Fuzhou basin can be divided into upper Pleistocene series and Holocene series, which include four formations from old to new. They are the Longhai formation ( Q3pl), Dongshan formation (Qhd), Changle formation (Qhc) and Jiangtian formation (Qhj), respectively. The Longhai formation can be divided into three members and belongs to the Pleistocene series, other three formations belong to the Holocene series.关键词
