Notes:
With the recent extension of K-Ar dating methods within the Upper Pleistocene time, the use of new standards is recommended to allow calibration and inter-laboratory comparisons. For this purpose, two pure microlitic groundmass reference materials were prepared from trachy-basaltic lavas: Trachyte (MDO-G) from Mont Dore, Puy de Sancy, Massif Central is around 250 000 years old; the second Trachyte (ISH-G) from the Isle of Ischia, Gulf of Naples (Italy), is historical: Arso flow erupted on Christmas 1301 - January 1302 AD.
