Thesis title:  Study of high pressure (HP) and ultra-high pressure (UHP) metamorphic rocks in the Makbal district in the Kyrgyz Northern Tien-Shan.
Supervisor:  Prof. Akira Takasu (2012-2014)

The Makbal district in the Kyrgyz Northern Tien-Shan is located in the western segment of the Central Asian Orogenic Belt (CAOB). The metamorphic rocks exposed in the Makbal district are divided into the Akdzhon and Scharkyrak Groups based on their metamorphic conditions (Fig 1.). The Akdzhon Group contains HP and UHP metamorphic rocks, whereas the Scharkyrak Group underwent greenschists facies metamorphism. The Akdzhon Group is divided into two contrasting metamorphic formations, the structurally lower Makbal Formation and the structurally overlying Neldy Formation. The Scharkyrak Group unconformably overlies the Neldy Formation. The Makbal Formation is mainly composed of metaquartzites and garnet-talc-chloritoid schists, which carry evidence of UHP metamorphism, i.e. coesite inclusions in garnets (e.g. Tagiri and Bakirov, 1990; Tagiri et al., 2010). Eclogites occur as lenticular bodies within the UHP matrix.
