International stage stratotypes
1996All of the Upper Carboniferous stages in the so-called ‘Heerlen Classification’, from the Chokierian to the Bolsovian, have their base stratotypes in northern England (the Westphalian D base stratotype has yet to be selected, although sites in South Wales will probably be strong contenders).

Stratotypes and an International Geochronologic Scale
1978An international geochronologic scale is needed in order to provide a single universal standard of reference for dating rock strata, or events recorded in rock strata, anywhere in the world. There are many possible means of relating rock strata and the geologic events they record to the passage of time--physical relations of strata (law of ...

Chapter A5 Langhian, serravallian, and tortonian historical stratotypes
1995Publisher Summary This chapter discusses Langhian, Serravallian, and Tortonian historical stratotypes. Chronostratigraphy does represent a basic common language of communication in Earth Sciences. However, most chronostratigraphic units of the standard Geologic Time Scale lack an appropriate and rigid definition in the rock stratigraphic record ...

Chapter A1 The aquitanian historical stratotype
1995Publisher Summary The Aquitanian fossiliferous marine deposits underlie a dark grey limestone with Planorbis and Limnaea. This unit is considered to be the top of the Aquitanian in this area. A level with Pecten beudanti is found above it, and contains a new fauna characteristic of the Burdigalian.
