摘要: 通过对位于辽西海岸带第四系地层的剖面测制、14C及OSL测年、地质环境综合样分析研究，将辽西海岸带分布的一套黄色—桔红色松散沉积物及其上部的一套灰白色含砾粉砂-粉砂-粘土质沉积物，按形成时代归入全新统中—上部，建立第四系全新统六股河组和大凌河组。Abstract: Through measuring the profiles of the Holocen stratigraphy located at the west coastal zone of Liaoning Province、14C、the OSL dating results, synthetical sample analysis on geological environment,we distributed a suit of khaki–nacarat loose accumulations and a suit of grey gravel bearing silt-silt-clay sediments above it to the middle-late Holocene sections according to their forming eras, and established the Holocene Liuguhe、Dalinghe Groups.
