The International Commission on Stratigraphy (ICS) has a long tradition of producing international charts that communicate higher-order divisions geological time and actual knowledge the absolute numerical ages their boundaries. primary objective ICS is to define precisely global standard set time-correlative units (Systems, Series, Stages) for stratigraphic successions worldwide. These are, in turn, basis Periods, Epochs Ages Geological Time Scale. Setting an fundamental expressing...
ABSTRACT Over the course of last decade concept Anthropocene has become widely established within and beyond geoscientific literature but its boundaries remain undefined. Formal definition as a chronostratigraphical series geochronological epoch following Holocene, at fixed horizon with precise global start date, been proposed, fails to account for diachronic nature human impacts on environmental systems during late Quaternary. By contrast, defining an ongoing geological event more closely...

Current debate on the status and character of Anthropocene is focussed whether this interval geological time should be designated as a formal unit epoch/series rank in International Chronostratigraphic Chart/Geological Time Scale, or it more appropriate for to considered an informal ‘event’ comparable significance with other major transformative events deeper time. The case formalizing chronostratigraphical base at approximately 1950 CE being developed by Working Group Subcommission...

A world-wide search for stratigraphic sections exposing the base of Nemagraptus gracilis Biozone, level selected to define global Upper Ordovician Series, resulted in recognition three potential boundary stratotypes, namely Fågelsång, Calera, and Dawangou sections, all which have been restudied during last four years.These fulfill most requirements a GSSP, their biozone boundaries can be correlated precisely with each other.Based on an assessment information now available, it is concluded...
Forty-three graptolite species belonging to fifteen genera are described from the upper Katian ornatus and pacificus biozones Hirnantian extraordinarius persculptus of Vinini Creek Martin Ridge reference sections north-central Nevada.Approximately half have not been previously recorded Nevada, six left in open nomenclature.Infraorder Neograptina Styracograptus gen.nov.are erected.The maximum diversity is organic-rich black shale lower part Biozone Formation.Species decreased abruptly at top...

This paper outlines the stratigraphic basis of a proposed Anthropocene Event. It considers diachronous event framework to be more appropriate for understanding than treating it as new geological series/epoch. Four general categories material evidence are identified particular relevance: 'artificial' strata with natural constituents; humanly modified ground; legacy sediments; and 'natural' geo-deposits containing artefactual material. All these arise from interaction mixing human, natural,...
Extensive work by the International Subcommission on OrdovicianStratigraphy (ISOS) has led to considerable progress in establish-ment of a new chronostratigraphic classification OrdovicianSystem which now includes seven stages (Webby 1998; Finney 2005).However, until recently, only three these global havebeen formally named and ratified Commissionon Stratigraphy (ICS). These are lower stage LowerOrdovician (Tremadocian or 1
North American Ordovician strata record a large shift in their neodymium isotopic composition ($$\Delta \epsilon _{\mathrm{Nd}\,}=\sim 7$$ ) at around 450 Ma. As part of continuing effort to understand this phenomenon, we studied the provenance Middle and Upper clastic sedimentary rocks along transect through southern Appalachian Ouachita Mountains using combination high‐resolution graptolite‐neodymium analysis U‐Pb dating detrital zircon. Taconian (Blountian)‐age sediment (ca. 465 Ma)...

Abstract Following the recent rejection of a formal Anthropocene series/epoch by Subcommission on Quaternary Stratigraphy (SQS) International Commission (ICS), and its subsequent confirmation Union Geological Sciences (IUGS), opportunity arises to reset definition Anthropocene. The case for informally recognizing be major planetary event Earth system transformation offers promising way forward, but this has been criticized proponents an series/epoch. In order move from assumption that it...
