我省沿海晓全新世地层发育,裸露地表,为陆相沉积,不整合于中全新世海相沉积层之上。解放后,福建省水文工程地质队,在沿海进行水文工程地质调查和钻探时,将全新世划分为上、下两部份,即长乐组、东山组。福建师大王绍鸿同志在1984年研究福州海湾演变时,将上部冲洪积相时代划归晓全新世,下部的海湾相、浅海相为中全新世。近三年来,我队担负沿海石英砂矿床的普查勘探中,据已获得的地层、孢粉、微体古生物、C~(14)同位素等资科,将前人建立的长乐组上部的泻湖相、风积相地层划归晚全新世。园在长乐县江田村发育最好,研究最详细,故称江田组。这样可与国内外地层划分对比。
On the coast of our province, the Holocene Holocene developed with bare land surface, which is continental sedimentary and unconformable over the mid-Holocene marine sediments. After the liberation, the Hydrological Engineering Geological Team of Fujian Province divided the Holocene into two parts above and below, Changle Formation and Dongshan Formation, during hydrological engineering geological survey and drilling along the coast. When studying the evolution of the Gulf of Fuzhou in 1984, Comrade Wang Shaohong of Fujian Normal University referred to the Holocene as the upper part of the alluvial accumulation phase, with the lower Gulf phase and the shallow marine phase as the middle Holocene. In the past three years, our team was responsible for the census and exploration of coastal quartz sand deposits. According to the information obtained from the strata, sporopollen, micro-organism and C ~ (14) isotopes, the upper lagoon phase , Aeolian strata are classified as late Holocene. Garden in Changle County, the best development of Jiangtian Village, the most detailed study, it said Jiangtian group. This can be compared with the stratification at home and abroad.
