Description | ||||||
The research area is situated within the northern adjacent part of the Momeik Town. It is constituted chiefly of metamorphic (metapelite, metacarbonate and metaigneous) and associated igneous rocks. The present work deals to describe the petrographic characters of granitic rocks and to investigate the depth of emplacement of granitic rocks based on not only geochemical data but also field observations. From the microscopic examination, the cooling temperature of the granitic rocks generally decreases from south to north. Based on geochemical data, the liquidus temperatures for the granitic rocks are 630 oC for biotite microgranite, 620 oC for leucogranite and 610 oC for tourmaline granite. The depth of crystallization of the granitic rocks of the study area interpreted from the schematic depthtemperature relation diagram might be assumed 21 km for tourmaline granite, 22 km for leucogranite and 23 km for biotite microgranite. Based on field criteria, the granitic rocks of the Momeik-Myitson area might have emplaced either in the upper level of mesozone or lower level of epizone. | ||||||
