| 摘 要： | 晚更新世末期，强劲古季风活动的结果，在中国西部形成沙漠－黄土堆积群（黄土高原及其以西或西北的沙漠区），当它到达陆架区以后，风蚀作用继续存在，会产生同样的地质效果，因而在中国东部陆架区，形成两个新的沙漠－黄土堆积群。其一为渤海沙漠－黄土堆积群，包括渤海海底，渤海海岸一带的古沙漠活动区和辽东半岛西岸，庙岛群以及山东蓬莱以西的含有孔虫的黄土沉积。其二为黄海沙漠－黄土堆积群，包括苏北浅滩和长江三角洲地区全

| Abstract: | At the close of Late Pleistocene,as a result of strong monsoon action,the desert loess deposit group was formed in western China(loess plateau and the desert region to its west).With its arrival in the shelf areas,two new desert-loess deposit groups were formed.One is the Bohai Sea desert-loess deposit group,including the floor of Bohai Sea and the desert zone along the coast and the loess deposits containing foraminifera distributed in the western coast of Liaodong Peninsula,the Miaodao Islands,and to the west of Penglai City,Shandong Province,the other is the Yellow Sea desert loess group,including the desert area in the North Jiangsu shoal and Yangtze River delta region prior to Holocene transgression and the Xiashu loess in the vicinity of Nanjing City. |
