"Preliminary Study on the Distribution of the Rock Units exposed in the Dobin- Sinkin Area, Momeik Township, Northern Shan State: Criteria for Stratigraphy" Naing Lin Naing Win Aye Aye Mar Soe Myint "The research area is situated within the Momeik Township. It chiefly constitutes metamorphic (metapelite, metacarbonate and metaigneous) and associated igneous rocks. The present work deals with the distributions of the rock units to support the stratigraphy. Based on the constituent mineral assemblages, Mommeik metamorphics in the study area can be grouped into three types: paragneisses (garnet biotite gneiss, biotite gneiss); metacarbonates (forsterite-graphite marble, phlogopite marble, diopside calcsilicate rock, diopside marble, white marble); metapelites and metasammites (silliminite schist, biotite schist, Skarn rock). Careful field observations on premetamorphic sedimentary structures, bedding characteristics and the mode of stratigraphic sequence indicate that Momeik metamorphic rocks may be assigned as metamorphic equivalents of dolomitic, calcareous and pelitic sequences of the Early Paleozoic of Shan Plateau. The exposed igneous rocks in the study area are the younger intrusives which are mainly granitic in composition including leucogranite and biotite microgranite. These igneous sequences may be regarded as the products of the magmatism which have been taken place during Tertiary period, specifically at Miocene." https://meral.edu.mm/records/8407
