“…The Lanping basin (99.0-99.7 • E, 26.0-26.87 • N), located in the western part of Yunnan Province, is famous for its metal ore deposits enriched with lead, zinc, copper, and silver [66]. Also, Burma is a country endowed with rich mineral resources that benefits from favorable geological conditions; thus, it has several world-renowned mineral deposits and mines [67]. For example, the Jinding deposit in the Lanping basin (yellow diamond in Figure S1a) and the Bawdwin mines (97.3 • E, 23.1 • N, blue diamond in Figure S1a) in northeastern Burma are world-class supergiant Pb-Zn deposits (associated with copper-nickel-cobalt paragenesis) [67].…”

The Tibetan Plateau (TP) is one of the world's most sensitive areas for climate change. Previous studies have revealed that air pollutants emitted from South and Southeast Asia can be transported to and have a negative impact on the TP. However, the majority of the investigators have focused on the pollutant transport processes from South Asian regions (i.e., India and Bangladesh) and parts of Southeast Asia, while the regions adjacent to the southeast fringe of the TP (i.e., Burma and the Sino-Burmese border) have been neglected. Here, fine particulate matter (PM 2.5 ) samples were collected during the period 11 March to 13 May 2018 at Gaomeigu, a high-altitude remote site in the southeastern margin of the TP. Characteristics, sources of PM 2.5 , and the potential source regions for different chemical components were investigated. During the sampling time, PM 2.5 mass loadings ranged from 3.79 to 54.57 µg m −3 , with an arithmetic mean concentration of 20.99 ± 9.80 µg m −3 . In general, major peaks of organic carbon (OC) and elemental carbon (EC) always coincided with high loadings of K + and NO 3 − , which implies that common combustion sources caused these species' concentrations to covary, while the daily variations of crustal elements showed different trends with the other chemical compositions, suggesting different source regions for crustal materials. Five source factors were identified as possible aerosol sources for PM 2.5 by positive matrix factorization (PMF). They are the mining industry (5.3%), characterized by heavy metal elements; secondary formation (18.8%), described by the high concentrations of NH 4 + and SO 4 2− ; traffic-related emissions (26.7%), dominated by carbonaceous species (especially soot-EC) and some metal elements; fugitive dust (15.2%), represented by crustal elements (Ti, Fe, and Mn), Ca 2+ , and Mg 2+ ; and biomass burning (34.0%), which is typified by high concentrations of K + , NO 3 − , char-EC, primary OC, and secondary OC. The concentration-weighted trajectory (CWT) analysis results showed that the northeast part of Burma is the potential source region for high concentrations of EC and NO 3 − due to biomass burning emissions, while the tourism industry surrounding Gaomeigu gave strong grid cell values of SO 4 2− as well as moderate values of EC and NO 3 − . Moreover, the mining industry in the southwest direction of Gaomeigu has important impacts on the zinc concentrations.

“…Myanmar, at the heart of this region, is highly prospective, however it remains a poorly explored minerals jurisdiction (Chhibber, 1934;Gardiner et al, 2014;Khin Zaw, 2017;Soe Win and Malar Myo Myint, 1998). The Tethys-related orogenies and concomitant magmatism are the major drivers for ore formation within this region.…”

“…Myanmar is a highly prospective minerals jurisdiction. It contains significant known deposits of tin, tungsten, copper, gold, zinc, lead, nickel, silver, jade and gemstones (Barber et al, 2017a;Chhibber, 1934;Gardiner et al, 2014;Khin Zaw, 2017; Soe Win and Malar Myo Myint, 1998), the metallogenesis of much of which is tied to its Mesozoic to Cenozoic tectonic history. However, the country remains relatively poorly explored, at least with modern exploration methods.…”

The crustal architecture of Myanmar imaged through zircon U-Pb, Lu-Hf and O isotopes: Tectonic and metallogenic implications

The Tethys margin in central and eastern Asia is comprised of continental terranes separated by suture zones, some of which remain cryptic. Determining the crustal architecture, and therefore the geological history, of the Eastern Tethyan margin remains challenging. Sited in the heart of this region, Myanmar is a highly prospective but poorly explored minerals jurisdiction. 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. The Eastern and the Main Range Provinces are associated with the Late Permian to Early Triassic closure of Palaeo-Tethys. The Mogok-Mandalay-Mergui Belt and Wuntho-Popa Arc are a response to the Eocene closure of Neo-Tethys. However, magmatic ages outside these two orogenic events are also recorded. 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. Eastern Province Permian I-type magmatism has evolved Hf (-10.9 to-6.4), while Main Range Province Triassic S-type magmatism also records evolved Hf (-13.5 to-8.8). The Mogok-Mandalay-Mergui Belt is here divided into the Tin Province and the Mogok Metamorphic Belt. The Tin Province hosts ca. 77-50 Ma magmatism with evolved Hf (-1.2 to-15.2), and  18 O of 5.6-8.3 ‰. The Mogok Metamorphic Belt exhibits a more complex magmatic and metamorphic history, and granitoids record Jurassic, Late Cretaceous, and Eocene to Miocene phases of magmatism, all of which exhibit evolved Hf values between-4.6 and-17.6, and  18 O between 6.3 and

Myanmar contains important deposits of tin, tungsten, copper, gold, gemstones, zinc, lead, nickel and silver. It has one of the most diverse and richly endowed collections of natural resources in Southeast Asia, largely reflecting a geological history stretching from the Late Triassic to the Miocene. At least three world class deposits include Bawdwin (lead-zinc-silver), Monywa (copper) and Mawchi (tin-tungsten). Myanmar can be divided into three principal metallotects: the Wuntho-Popa Arc, comprising subduction-related granites with associated porphyry-type copper-gold and epithermal gold mineralisation; the Mogok-Mandalay-Mergui Belt hosting both significant tin-tungsten mineralisation associated with crustal melt granites, and key orogenic gold resources; and the Shan Plateau with massive sulphide-type lead-zinc deposits. Myanmar as a jurisdiction remains poorly understood and underdeveloped with regards its natural resources. We have built a Geographic Information System database of known Myanmar deposits, outcrops and mineral occurrences as a tool for exploration targeting.
