interval_notes:	The GSSP is defined in a speleothem (KM-A) with a modelled age of 4250yr bk2 (before AD2000), where the stable isotope profile shows a shift to heavier isotopic values, reflecting an abrupt reduction in precipitation due to weakening of the monsoon across the Indian sub-continent and southeast Asia.
