have been obtained from an I-type granite from Phuket in Thailand, albeit with zircon rims showing a Late Cretaceous thermal overprint of 81.2 1.2 and 85–75 Ma (Searle et al., 2012). And associated with the Mogok metamorphic complex in Myanmar there are numerous examples of granite-emplacement ages extending up to the Eocene (Searle and Morley, 2011; Mitchell et al.,2012).
