Abstract

Abstract The Carboniferous chronostratigraphic scale is a hierarchy of two subsystems, six series and seven stages developed during nearly two centuries of research. Carboniferous stage nomenclature developed with the proposal of numerous regional stages/substages based primarily on palaeobotanical, foraminiferal and ammonoid biostratigraphy, especially in Western Europe, the former Soviet Union, China and the USA. From the regional stages, seven ‘global stages’ have been identified (in ascending order): Tournaisian, Visean, Serpukhovian, Bashkirian, Moscovian, Kasimovian and Gzhelian. Three of the four ratified Carboniferous GSSPs use conodont evolutionary events as the primary signal for correlation – bases of Tournaisian, Bashkirian and base of Asselian. The GSSP of the Visean base has a foraminiferal event as its primary signal. Issues in the development of a Carboniferous chronostratigraphic scale include the rank of chronostratigraphic units, provinciality, conodont biostratigraphy, palaeobotanical biostratigraphy and the development of astrochronology and other methods of chronology and correlation.
石炭系年代地层尺度:历史、现状与展望
石炭系年代地层尺度是近两个世纪研究发展起来的两个亚系、六个系列和七个阶段的层次结构。石炭纪阶段命名法的发展主要基于古植物学、有孔虫和氨类生物地层学,特别是在西欧、前苏联、中国和美国,提出了许多区域阶段/亚阶段。从区域阶段来看,已经确定了七个“全球阶段”(按升序排列):图尔奈西安阶段、维桑阶段、谢尔普霍夫阶段、巴什基利安阶段、莫斯科阶段、卡西莫维安阶段和格热利安阶段。在已确认的4个石炭系gssp中,有3个将牙形石演化事件作为图尔奈系、巴什基系和亚塞利亚系对比基础的主要信号。维桑基地的GSSP有一个有孔虫事件作为它的主要信号。石炭系年代地层尺度发展的问题包括:年代地层单元等级、省域、牙形石生物地层、古植物生物地层、天体年代学及其他年代学和对比方法的发展。
