Patzi Fm

Period: 
Neogene

Age Interval: 
Latest Miocene-Pliocene


Province: 
Myanmar Central Basins

Type Locality and Naming

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


Lithology and Thickness

This Fm consists mainly of sandstones with pebble lenses in places, intercalated with mottled clay and mudstones in the middle part. Measured thickness in the type area is >290 m.
