International Subcommission on Stratigraphic Classification [Report No. 7a; editor H. D. Hedberg]: Introduction to an International Guide to Stratigraphic Classification, Terminology, and Usage. Boreas, Vol 1, pp. 199–211. Oslo, 1st September, 1972. [Co-published with Lethaia, Vol. 5, pp. 283–295]. The International Subcommission on Stratigraphic Classification (ISSC), a subcommission of the IUGS Commission on Stratigraphy, has been working for the last 15–20 years towards the preparation of an International Guide to Stratigraphic Classification, Terminology, and Usage. The purpose of the Guide is to promote international agreement on principles of stratigraphic classification and to establish internationally acceptable stratigraphic terminology and rules of stratigraphic procedure. The Introduction explains the background of its preparation.     

Summary of an International Guide to Stratigraphic Classification,Terminology, and Usage

International Subcommission on Stratigraphic Classification [Report No. 7b; editor H. D. Hedberg]: Summary of an International Guide to Stratigraphic Classification, Terminology, and Usage. Boreas, Vol. 1, pp. 213–239. Oslo, 1st September, 1972. [Co-published with Lethaia, Vol. 5, pp. 297–323]. Six published reports (and some 40 circulars) of the International Subcommission on Stratigraphic Classification (ISSC) constitute the principal bases for the initial edition of an International Guide to Stratigraphic Classification, Terminology, and Usage. The published reports on Lithostratigraphic Units, Biostratigraphic Units, Chronostratigraphic Units, and Stratotypes are advance chapters of the Guide. The following Summary, which with the preceding Introduction will form the first chapter of the completed Guide, provides a concise and condensed statement of principles, definitions, and proposed rules, which are elaborated in more detail in the published reports and individual chapters of the Guide.     

Geohistorical Stratigraphy and Stratigraphic Guides

A different understanding of the stratigraphic science methodology is considered. The classical geohistorical content of stratigraphy is set against the latest formal classification approach recorded in the International Stratigraphic Guide. Some provisions of the Stratigraphic Code of Russia and the International Stratigraphic Guide are studied. The described confrontation between the two concepts can be expressed by a formula: stratotype or limitotype.

Field Geologist's Guide to Lithostratigraphic Nomenclature in Australia

Abstract

Stratigraphic nomenclature in Australia was regulated from 1950 by four successive editions of the Australian Code of Stratigraphic Nomenclature. The International Stratigraphic Guide was adopted for stratigraphic nomenclature in Australia in 1978 and thus superseded the Australian Code. Certain provisions of the Code and certain Australian practices still pertained, however, and these have been formulated as Notes, intercalated with extracts from Chapters 2–5 of the International Guide to form the Field Geologist's Guide to Lithostratigraphic Nomenclature in Australia. Biostratigraphic and chronostratigraphic nomenclatures are excluded. The lithostratigraphic nomenclature of igneous and metamorphic rock units is also excluded, as recommendations are still being formulated. Procedures for reserving, defining, and publishing stratigraphic names are administered by the Stratigraphic Nomenclature Committee in conjunction with the Bureau of Mineral Resources through the Bureau's Central Register of Stratigraphic Names.

Status of Stratigraphy Research in China

Scientific research and productive practice for earth history are inseparable from the accurate stratigraphic framework and time framework. Establishing the globally unified, precise and reliable chronostratigraphic series and geological time series is the major goal of the International Commission on Stratigraphy(ICS). Under the leadership of the ICS, the countries around the world have carried out research on the Global Standard Stratotype-section and Points(GSSPs) for the boundaries of chronostratigraphic systems. In the current International Chronostratigraphic Chart(ICC), 65 GSSPs have been erected in the Phanerozoic Eonothem, and one has yet been erected in the Precambrian Eonothem. Based on the progress of research on stratigraphy especially that from its subcommissions, the ICS is constantly revising the ICC, and will publish a new International Stratigraphic Guide in 2020. After continual efforts and broad international cooperation of Chinese stratigraphers, 10 GSSPs within the Phanerozoic Eonothem have been approved and ratified to erect in China by the ICS and IUGS. To establish the standards for stratigraphic division and correlation of China, with the support from the Ministry of Science and Technology, the National Natural Science Foundation of China and the China Geological Survey, Chinese stratigraphers have carried out research on the establishment of Stages in China. A total of 102 stages have been defined in the "Regional Chronostratigraphic Chart of China(geologic time)", in which 59 stages were studied in depth. In 2014, the "Stratigraphic Chart of China" was compiled, with the essential contents as follows: the correlation between international chronostratigraphy and regional chronostratigraphy of China(geologic time), the distributive status of lithostratigraphy, the characteristics of geological ages, the biostratigraphic sequence, the magnetostratigraphy, the geological events and eustatic sea-level change during every geological stage. The "Stratigraphical Guide of China and its Explanation(2014)" was also published. Chinese stratigraphers have paid much attention to stratigraphic research in south China, northeast China, north China and northwest China and they have made great achievements in special research on stratigraphy, based on the 1:1000000, 1:250000, 1:200000 and 1:50000 regional geological survey projects. Manifold new stratigraphic units were discovered and established by the regional geological surveys, which are helpful to improve the regional chronostratigraphic series of China. On the strength of the investigation in coastal and offshore areas, the status of marine strata in China has been expounded. According to the developing situation of international stratigraphy and the characteristics of Chinese stratigraphic work, the contrast relation between regional stratigraphic units of China and GSSPs will be established in the future, which will improve the application value of GSSPs and the standard of regional stratigraphic division and correlation. In addition, the study of stratigraphy of the Precambrian, terrestrial basins and orogenic belts will be strengthened, the Stratigraphic Chart of China will be improved, the typical stratigraphic sections in China will be protected and the applied study of stratigraphy in the fields of oil and gas, solid minerals, etc. will be promoted. On the ground of these actions, stratigraphic research will continue to play a great role in the social and economic development of China.

新国际地层表简介

2004年国际地层委员会将地球上的岩石划分成两大部分,即显生宇和前寒武系。两者划分的依据不同,显生宇是依据"全球层型剖面和层型点",而前寒武系则是依据"全球标准地层年龄"。为了建立一个"自然的"前寒武纪地质年代表,人们提出了2004~2008年前寒武系划分参考方案,它指明了前寒武纪的研究方向。     

A new Geologic Time Scale, with special reference to Precambrian and Neogene

A Geologic Time Scale (GTS2004) is presented that integrates currently available stratigraphic and geochronologic information. Key features of the new scale are outlined, how it was constructed, and how it can be further improved. The accompanying International Stratigraphic Chart, issued under auspices of the International Commission on Stratigraphy (ICS), shows the current chronostratigraphic scale and ages with estimates of uncertainty for all stage boundaries. Special reference is made to the Precambrian part of the time scale, which is coming of age in terms of detail, and to the Neogene portion, which has attained an ultra-high-precision absolute-age calibration.     

二叠系全球界线层型和点位(GSSP)研究进展

新的二叠纪年代地层系统为国际二叠系分会通过并正式纳入“国际地层表”后,已有5个GSSP得到正式批准,它们分别是阿瑟尔阶(二叠系)、吴家坪阶、卡匹敦阶、沃德阶和罗德阶的底界。长兴阶底界的GSSP提案在国际二叠系分会投票中,以94 %赞成票通过,并交国际地层委员会进行投票表决。国际二叠系分会最近的主要工作重点将是早二叠世乌拉尔统内空谷阶底界、亚丁斯克阶底界和萨克马尔阶底界的确定工作,由B.I.Chuvashov领导的界线工作组正在对俄罗斯乌拉尔南部的界线剖面进行工作。国际二叠系分会力争在2 0 0 6年底前完成投票工作,并使二叠纪的地层研究全面转入国际间对比等层型后研究

辽宁南华系殷屯组及永宁组冰碛岩沉积特征

通过对辽宁地区出露的新元古代殷屯组、永宁组调查研究取得了新认识,认为辽宁地区存在南华纪地层,以新元古代殷屯组、永宁组为代表,可划分出二次冰川活动（二个冰期和一次间冰期）的沉积,自下而上为殷屯冰期（第一次冰期）、八家子间冰期、河冰期（第二次冰期）.依据殷屯组和永宁组冰碛物组合特点及接触关系,并结合碎屑锆石U-Pb（LA-ICP-MS）同位素测年成果,推测辽宁南华系殷屯组、永宁组形成时代应小于1000 Ma,与南方南华纪形成的时间基本接近或略早（约850 Ma）.

The Ordovician Mukteian Horizon of the Siberian Platform: paleontological substantiation,distribution, and correlation of sections

The new-generation regional stratigraphic chart of the Siberian Platform was accepted by the Interdepartmental Stratigraphic Committee of Russia in April 2013. Two main supplements to the chart of 1979 were made: (1) the new scale of stages, accepted by the International Commission on Stratigraphy in 2008, was presented for the Ordovician System along with the previous British standard and (2) the nomenclature of the regional stratigraphic units was supplemented by the Mukteian Horizon, which occupies an intermediate position between the Vikhorevian and Volginian Horizons. The first substantiation of the necessity of viewing this stratigraphic interval as an independent horizon was made in 1980, after it had become possible to use well cores for a more precise definition of the paleontologic characteristics and boundaries of the Vikhorevian Horizon, originally detected from several isolated sections in the Irkut amphitheater with an indistinct boundary with the overlying Volginian Horizon. Recent data, particularly those from drilling, permit a more complete paleontological substantiation of the Mukteian Horizon, consideration of its distribution in different structure-facies zones, and correlation of type sections.
