摘要
山东东部近海地区出露的晚中生代深水沉积受到地质学界越来越多的关注。但目前,关于晚中生代地层沉积充填特征还未有过系统细致的研究。选取出露于青岛灵山岛、崂山、诸城桃林、海阳丁字湾、即墨周戈庄等山东东部近海地区的5个典型剖面,开展了详细的地层沉积特征研究。晚中生代地层主要为莱阳群和青山群沉积,莱阳群岩性以深水重力流沉积岩和硅质碎屑岩为特征;青山群岩性以火山碎屑岩为特征。总体上,莱阳群到青山群自下而上为海进-海退过程。
Late Mesozoic deep-water sediments occur widely in the area off Eastern Shandong Peninsula, which have received great attention from geologists recently. However, the research on Late Mesozoic and its sedimentary characteristics of the area has not been systematically conducted in details so far. In this paper, the five field typical profiles at the Lingshan Island, Laoshan, Taolin, Dingzi Bay and Zhougezhuang areas are selected for detailed case studies. The Late Mesozoic includes the Laiyang and Qingshan Groups. The Laiyang Group is characterized by gravity flow and siliceous clastic deposits, and the Qingshan Group is characterized by pyroclastic rocks. From the Laiyang Group to the Qingshan Group it is a transgression-regression cycle.
