Cross-correlation between insolation intensities and a combination of sedimentary characters is introduced to obtain precise time calibration of sedimentary cycles. The first step is to transfer the section scale into ages using power spectra comparing the main periods with orbital cycles, while in the second step the standardized values of sedimentary signals are cross-correlated with the stan...

The definition of a Middle–Upper Pleistocene Subseries boundary is discussed. This boundary is at present not formally defined, but has up till now been placed at the beginning of the Last Interglacial (Eemian, Mikulino, Sangamonian, etc.) or Marine Isotope Stage 5. Although it may seem attractive to define the boundary in an ocean sediment sequence, the inherent imprecision of most of such seq...

The North Atlantic INTIMATE group of the INQUA Palaeoclimate Commission has previously recommended an Event Stratigraphy approach for the synchronisation of records of the Last Termination using the Greenland GRIP isotopic record as the regional stratotype and INTCAL98 for the calibration of radiocarbon dates [Lowe, J.J., Hoek, W., INTIMATE Group, 2001. Inter-regional correlation of palaeoclima...

Foraminiferal revision of the Holkerian Stratotype Britain at Barker Scar, Holker Hall, south Cumbria, UK, allows subdivision section into Cf4?, Cf5? and Cf5? subzones (the latter being further subdivided lower Cf5?1 upper Cf5?2 intervals). The base subzone bed C from middle part C, occur 14 m 10.5 m, respectively, below traditional basal boundary K. boundaries these foraminiferal within main i...

The International Union of Geological Sciences has approved a new addition to the geologic time scale: the Ediacaran Period. The Ediacaran is the first Proterozoic period to be recognized on the basis of chronostratigraphic criteria and the first internationally ratified, chronostratigraphically defined period of any age to be introduced in more than a century. In accordance with procedures est...

Abstract The process for the formal ratification of proposed Anthropocene Epoch involves identification a globally isochronous stratigraphic signal to mark its starting point. search Global Boundary Stratotype Section and Point (GSSP), unique reference sequence that would be used fix start epoch, is in progress but none candidate sections are located Africa. We assessed currently available evid...
