论层序地层与岩石地层单位之间的关系——兼论沉积岩区1∶5万区域地质调查中填制“层序—组图”的双重表示方法

从时空关系出发讨论层序地层学与岩石地层学等分支学科之间的关系。建议采用两类主要地层分类系统的多重地层划分方案，把层序地层单位作为相对独立的辅助性地层单位。简述层序地层单位与岩石地层单位之间的几种关系。把层序地层方法用于山东淄川、文祖幅区调中，提出在沉积岩区１∶５万区调中填制“层序—组图”的双重表示方法

ON THE RELATIONSHIP BETWEEN SEQUENCE STRATIGRAPHIC UNITS AND LITHOSTRATIGRAPHIC UNITS

In the present paper the relationship is discussed between sequence stratigraphy and other stratigraphic branches such as lithostratigraphy. In the multiple stratigraphic division, chronostratigraphy and lithostratigraphy are regarded as the chief disciplines, and the others as supplementary disciplines of stratigraphy. Among the supplementary disciplines, sequence stratigraphy is relatively independent, being of both chronostratigraphic and lithostratigraphic natures, and may play an important part in improving the boundaries of both chronostratigraphical and lithostratigraphical units. Some possible relationships between sequence stratigraphic and lithostratigraphic units are discussed. The sequence stratigraphic approach has been applied in the regional geological surveys of the Zibo and Wenzu Sheets. It is suggested that a duplex mapping method of "sequence unit lithostratigraphic unit" may be used in 1∶50,000 geological mapping in sedimentary areas.
