QUATERNARY SEDIMENTARY ENVIRONMENT AND SEA-LEVEL FLUCTUATIONS ON THE NORTHERN COAST OF BOHAI BAY, LIAONING PROVINCE

摘要: 辽宁省海岸带ZK4孔位于下辽河凹陷区内，孔深25.5 m，共揭露地层24层，包括全新统和部分晚更新统.通过对24个样品鉴定和环境分析，共分辨出2个海相层及内部7次海平面的波动.

Abstract: The 25.5 m deep Borehole ZK4, located in the Lower Liaohe River depression in the coastal zone of Liaoning Province, explores 24 hidden layers of strata, involving Holocene and part of Pleistocene. By analysis on 24 samples for forming environment, 2 marine beds and 7 times of sea-level fluctuations are identified.
