Taungtalone Sandstone Fm base reconstruction

Taungtalone Sandstone Fm

Period: 
Neogene

Age Interval: 
Late Early Miocene


Province: 
Myanmar Central Basins

Type Locality and Naming

Pegu (Bago) Yoma-Sittaung Basin, [Original Publication: Barber, A. J., Khin Zaw & Crow, M. J. (eds) 2017. Myanmar: Geology, Resources and Tectonics. Geological Society, London, Memoirs, 48, 169-183]

[Figure: Map showing location of sub-basins of the Central Myanmar Basin (after Myint Thein and M. Maung 2017)]


Lithology and Thickness

An 800 m thick unit of sandstones with some siltstone and shale generally exposed in the cores of anticlines; the sandstones are thick to very thick bedded and fine to coarse grained.
