Period: 
Paleogene

Age Interval: 
Early Eocene.


Province: 
NW.India Rajastan-Barmer Basin

Type Locality and Naming

OUTCROP: Type section is in Outcrops at Mataji ka Dungar. [Original Publication: Shrivastava, B.P. And S. Srinivasan, 1963: Geology of Bikaner-Barmer area, ONGC, Dehradun: report (Unpublished)]. Reference section: Botia Hill section and tube well sections at Botia, Bhadka and Bhimda villages

Coarse-grained sandstone. It comprises dominantly of ferruginous coarse-grained sandstone. At base, a clay bed is seen. The maximum thickness of this formation is about 180m


Lithology Pattern: 
Coarse-grained sandstone


Relationships and Distribution

Lower contact

The lower boundary of the formation is gradational with underlying Akli Fm. However, in the easternmost part around Jhak village, the formation directly overlies the basement.

Upper contact

The upper boundary is unconformable with overlying Kapurdi Fm.
