International commission on stratigraphy
A branch of geochronology that deals with the quantitative (numerical) measurement of geologic time. The abbreviations ka for thousand (103), Ma for million (106), and Ga for giga (109) years are used. Facies. The term “facies” originally meant the lateral change in lithologic aspect of a stratigraphic unit.Stratotype (type section) The designated exposure of a named layered stratigraphic unit or of a stratigraphic boundary that serves as the standard of reference.A stratotype is the specific stratal sequence used for the definition and/or characterization of the stratigraphic unit or boundary being defined. 2. Unit-stratotype.
