“…Bande and Prakash, 1986; the magnetostratigraphic polarity of these deposits (Benammi et al, 2002) and recent U/Pb and fission-track ages of detrital zircons (Tsubamoto et al, 2002(Tsubamoto et al, , 2011Zaw et al, 2015) indicate a correlation with the chron C38n, dated between 40.1 and 38.6 Myr (Gradstein et al, 2012). Pondaung deposits are thus contemporary with the end of the Middle Eocene Climatic Optimum (MECO), the most prominent transient warming episode of the middle Eocene, and its subsequent cooling event (Bohaty and Zachos, 2003;Villa et al, 2008;Bijl et al, 2010;Bosboom et al, 2014).…”
