The Mogok Metamorphic Belt (MMB), situated in central Myanmar, contains an assemblage of high -grade metamorphic rocks believed to have been formed during a regional Early Eocene -Oligocene metamorphic event. We newly found Grt -Opx granulite in the Mogok area, which was formed under pressure -temperature (P -T ) conditions estimated as being 6.5 -8.7 kbar and 800 -950 °C. Based on the results of EPMA U -Th -Pb Mnz dating, the central MMB, which runs through the Mogok, Mandalay, and Meikthila areas, is characterized by an Eocene to Oligocene deformation and fluid infiltration event. In addition, several Mnz grains from the Meikthila and Mandalay areas record ages of the Late Triassic (~ 200 Ma) and Cretaceous (~ 80 Ma and 110 Ma) geologic events.

Slope stability analysis along the road between Yinmabin and Kalaw, in Mandalay Region and Shan State was carried out aiming to gain preventive measure for the landslide due to the lack of consideration on landslide hazards and associated risk. The rocks comprise the sedimentary rocks of Plateau Limestone Group, Loi-an Group and Kalaw Red Bed, and the Yinmabin Metamorphics. Notably, four types of landslides such as rockfall, debris flow, creep and slump have been identified along this road. Rockfall is the commonest landslide mainly occurs along the manmade road cuttings generating potential threats to human life triggered by heavy and prolong rainstorm. Slope Mass Rating (SMR) values indicated that Yinmabin Meamorphics is the most vulnerable to landslide. Three types of failures such as wedge, plane and toppling failures are confirmed by kinematic analysis. Moreover, a total of three landslide hazard zones is interpreted based on geological and geotechnical parameters. These zones are described as Landslide Hazard Zone I (west of Yinmabin), Zone II (eastern part of Yebokson and western part of Kyatsakan) and Zone III (the area between Nampandet and Wetphuye). Remedial measures have been proposed to mitigate the hazard.
