Via phlogopite inclusions, the Mogok marble emplacement has been dated at a minimum age of approximately 18.7 million years (Garnier et al., 2006). In the Mogok area there are also schist and quartz veins cutting across the marble units.

Pein-Pyit (Painpyit; Pyan Pyit), Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Myanmar : The principal rocks are granite pegmatite, leucogranite, spinel-clinohumite-phlogopite marble, chondrodite-phlogopite-graphite marble and spinel-bearing & forsterite marble, ...
Quebul Fine Minerals / PHLOGOPITE
A very good specimen of gemmy phlogopite crystals sitting on a white marble base from Mogok Township, Myanmar (Burma). Gemmy crystals are rare for any mica species. The main phlogopite crystal of 16 mm is a sharp hexagon. The quality is superb – gemmy crystals with good transparency, light yellow-green color and strong luster.

2007年3月1日 · Diopside-phlogopite marble predominates from Kyaukse northwards, while schists and micaceous quartzites are most abundant from Myodwin southwards. Meta-carbonates are absent in the Payangazu and Nattaung quarries.

Spinels are found in the spinel-bearing marble. Rubies or spinels have not been found in the phlogopite-bearing marble bands. Gem mining is performed in typical gwè-dwin scheme. Numerous lebins are also in operation, where ruby, spinel, diopside, scapolite and sphene are recovered from the alluvium. - Ted Themelis (2008) Gems and Mines of Mogok
demonstrate a complex variety of parageneses in the Mogok Tract. Euhedral spinel, graphite, phlogopite, and diopside are consistent with metamorphism within a dolomitic marble, but the F-dominant clinohumite and large spinels with highly modified forms and wormy embayments indicate metasomatic effects.
A preliminary stable isotope study on Mogok Ruby, Myanmar
In this paper, we describe a mineralogical, geochemical, and geochronological study of ruby and titanite in ruby-bearing marbles obtained from an outcrop in the Mogok Stone Tract, central Myanmar. Petrographic observations have shown that titanite generally occurs in the marble matrix or occurs as inclusions in ruby.
