The Mogok-Mandalay-Mergui Belt is here divided into the Tin Province and the Mogok Metamorphic Belt.
Eastern Province Permian I-type magmatism has evolved εHf (-10.9 to -6.4), while Main Range Province Triassic S-type magmatism also records evolved εHf (-13.5 to -8.8). We present new zircon U-Pb, Lu-Hf and O isotope data from magmatic rocks across Myanmar, which we append to the existing dataset to isotopically characterize Myanmar’s magmatic belts. However, magmatic ages outside these two orogenic events are also recorded. The Mogok–Mandalay–Mergui Belt and Wuntho–Popa Arc are a response to the Eocene closure of Neo-Tethys. The Eastern and the Main Range Provinces are associated with the Late Permian to Early Triassic closure of Palaeo-Tethys. A better understanding of Myanmar’s mineralization can only be realized through a better understanding of its tectonic history, itself reflected in at least four major magmatic belts. Sited in the heart of this region, Myanmar is a highly prospective but poorly explored minerals jurisdiction. Determining the crustal architecture, and therefore the geological history, of the Eastern Tethyan margin remains challenging. The Tethys margin in central and eastern Asia is comprised of continental terranes separated by suture zones, some of which remain cryptic.
