Redefinition and base of Quaternary and Pleistocene

Excuse me for writing in English. I received the following message from a colleague. I suggest (if still necessary) the relevant pages should be modified accordingly:

Dear Quaternary colleague,

The International Union of Geological Sciences (IUGS ) has recently ratified to redefine the base of the Quaternary and Pleistocene at 2.6 Ma (see below). The end of a long lasting battle?

REDEFINITION OF THE BASE OF QUATERNARY SYSTEM/PERIOD, AND OF THE BASE OF THE PLEISTOCENE SERIES/EPOCH

The IUGS Executive Committee has ratified a request from the IUGS International Commission on Stratigraphy (ICS) regarding the definition of the base of Quaternary System/Period (and top of the Neogene System/Period), and redefinition of the base of the Pleistocene Series/Epoch (and top of the Pliocene Series/Epoch). The ICS submitted for IUGS ratification its recommendation that:

1) the base of the Pleistocene Series/Epoch be lowered such that the Pleistocene includes the Gelasian Stage/Age and its base is defined by the Monte San Nicola GSSP, which also defines the base of the Gelasian;

2) the base of the Quaternary System/Period, and thus the Neogene-Quaternary boundary, be formally defined by the Monte San Nicola GSSP and thus be coincident with the bases of the Pleistocene and Gelasian; and

3) with these definitions, the Gelasian Stage/Age be transferred from the Pliocene Series/Epoch to the Pleistocene.

Predlog za združitev

Predlagam, da se Geologija kvartarja združi v Kvartar. Menim, da je vsebina v kontekstu članka. Pinky sl (pogovor) 12:16, 13. januar 2014 (CET)

Se strinjam. Argument je podoben kot v primeru 'Zgodovina srednjega veka' vs. Srednji vek. --Cabana (pogovor) 21:25, 23. januar 2014 (CET)
