The study area, which is a segment of the Mogok Metamorphic Belt, is mainly composed of metamorphic rocks, granitic and syenitic\nrocks. \nThe main purpose of this study is to constrain metamorphic P-T paths of the study area based on detailed petrographic observations, bulk-rock chemistry of XRF and mineral geochemistry ofEPMA using phase equilibria modelling. \nIgneous rocks are minor intrusions which occur as mall outcrops within the study area, but they should be makeweights because P-7' condition of the study area is detennined only on a metamorphic basis. The metamorphic rocks covered about 90% of the whole area and they are sillimanite-gamet-biotite±ilmenite gneiss, garnet­biotite gneiss, spinel-diopside-forsterite-phlogopite±graphite marble, white marble and calc-silicate rocks. \nA new contribution of felsic and mafic granulitic rocks are observed in the study area. It is characterized by a mineral assemblage that was developed under high-grade metamorphic conditions. Taking the metamorphic rock units of the study area into consideration, granulitic rock is fairly exposed and it is associated with sillimanite-gamet-biotite gneiss and intruded by syenitic and granitic rocks. Granulite can be subdivided into two distinct units based on pyroxene percentage ( < and > 30%); felsic granulite (<30%) (sapphirine-hypersthene-gamet-biotite granulite) and mafic granulite (>30%) (pyroxene granulite), respectively. \nP-T calculation indicates sillimanite-garnet-biotite !,>neisses in the study area have reached up to granulite facies (740-810 °C & 6.2-9.3 kbar), characterized by the mineral assemblages and petrochemical results from EPMA and XRF. The P-1' condition of granulitic rocks in the study area should probably be the same as and/ or greater than the P-T condition of the high-grade gneiss of the study area, according to the mineral assemblages of orthopyroxene + garnet + sillimarute + sapphirine + hercynite in felsic granulite and that of clinopyroxene + biotite + plagioclase in mafic granulite. In the study area, sapphirine + hercynite + silica of granulite also indicate that it probably perform as ultra-high temperature mineral assemblage leading finally to an ultra-high temperature metamorphism (UHT) of Mogok Metamorphic Belt\n(MMB)."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"Mogok Metamorphic Belt, Igneous rocks, granulitic rock, felsic granulite"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-07-05"}],"displaytype":"preview","filename":"Wai Yan Lai Aung (Geo).pdf","filesize":[{"value":"835 KB"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/8955/files/Wai Yan Lai Aung (Geo).pdf"},"version_id":"67538d57-f7c8-4b41-8af9-8d599b7fec6c"}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_awarding_university":"University of Yangon"}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Wai Yan Lai Aung"}]}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2016-05-31"},"item_title":"Mineralogy and Petrology of the Igneous and Metamorphic Rocks of the Mount Loi-Sau and  its Environs, Momeik Township,  Shan State (North)","item_type_id":"21","owner":"12","path":["1582967711045"],"publish_date":"2023-07-05","publish_status":"0","recid":"8955","relation_version_is_last":true,"title":["Mineralogy and Petrology of the Igneous and Metamorphic Rocks of the Mount Loi-Sau and  its Environs, Momeik Township,  Shan State (North)"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2023-07-05T15:54:58.682670+00:00"}
