| 摘 要： | 由于陆相地层 ,尤其火山岩系的复杂性 ,研究者众多且多局限一隅 ,以往建立起的地层序列常只适用于某一地区 ,并且出现同物异名或异物同名现象。正确理解和运用《国际地层指南》、《中国地层指南》,是准确划分中生代陆相火山岩盆地地层的理论依据。借鉴层序地层学的方法 ,对划分山东省白垩纪岩石地层层序与火山岩盆地地层序列有了新的认识 :南、北莱阳群虽在岩性组合上有较大差异 ,但仍可归于同一岩石地层单位 ;大盛群与青山群既不是严格的上下关系 ,也不是完全的同期相变 ,二者呈交叉对应关系 ,大盛群的底界稍高 ;王氏群的林家庄组和辛格庄组应修订为寺前村组和孟疃组 ,置于大盛群中。

| Abstract: | Owing to the complication of the continental strata, especially the volcanic rock series, these strata have been studied by many scholars, but these studies have been mostly limited to a corner. The stratigraphic sequences established in the past are only applied to a certain region and there occurred many synonyms and homonyms. A right understanding of the “International Stratigraphic Guide” and “Stratigraphic Guide of China” and an application of them is the theoretical basis for the precise division of the Mesozoic continental strata of the volcanic basin. By using the method of sequence stratigraphy, a new knowledge of the division of the Shandong Cretaceous lithostratigraphic sequences and the stratigraphic sequences in the volcanic basins has been acquired as follows: although there are great differences in the lithology and composition between the southern and northern Laiyang Groups, the two groups may be still assigned to the same lithostratigraphic unit; strictly speaking, the Dasheng Group does not overlie the Qinshan Group and in the meantime they are not a complete synchronous facies change; there are cross corresponding relations between the two; the basal boundary of the Dasheng Group is a little higher; the Linjiazhuang and Xingezhuang Fourmations of the Wangshi Group should be revised and replaced respectively by the terms Siqiancun and Mengtuan Formations and placed in the Dasheng Group. |
