Taunggale Fm base reconstruction

Taunggale Fm

Period: 
Paleogene

Age Interval: 
Middle Eocene


Province: 
Myanmar Central Basins

Type Locality and Naming

Irrawaddy River Delta, the Taunggale Fm has been penetrated by the Pathein-1 and Tada U-1 wells. [Original Publication: Barber, A. J., Khin Zaw & Crow, M. J. (eds) 2017. Myanmar: Geology, Resources and Tectonics. Geological Society, London, Memoirs, 48, 219–260]

Lithology and Thickness

Sandy claystone. It is mainly composed of shales and sandstones.


Lithology Pattern: 
Sandy claystone


Relationships and Distribution

Lower contact

Conformable with Kanbala Fm

Upper contact

Overlain by a hiatus from Priabonian to Rupelian. Followed by Tumyaung Fm

Regional extent

It is developed in Irrawaddy River Delta. This unit can be correlated with the Late Eocene sequences of the Minbu-Salin Basin.
