Ghaggar-Hakra Fm

Period: 
Cretaceous

Age Interval: 
Early Cretaceous


Province: 
NW.India Rajastan-Barmer Basin

Type Locality and Naming

SUBSURFACE: [Referred Publication: John Dolson, Stuart D. Burley, V.R. Sunder, V. Kothari, Bodapati Naidu, Nicholas P. Whiteley, Paul Farrimond, Andrew Taylor, Nicholas Direen, and B. Ananthakrishnan, 2015 : The Discovery of the Barmer Basin, Rajasthan, India, and its petroleum geology : AAPG Bulletin, 99 (issue 3, 1 Mar 2015), pp. 433-465; https://doi.org/10.1306/10021414045]


Lithology and Thickness

Sandstone. Comprised of sandstones. It is divided into two members: Pushka Member, Kamyaka Member; or subdivided by named sandstone units (see Depositional setting)
