Badami Gr base reconstruction

Badami Gr

Period: 
Tonian

Age Interval: 
late Tonian


Province: 
Proterozoic S.India Kaladgi Basin

Type Locality and Naming


Lithology and Thickness

Sandstone with a lower Kerur Fm and upper Katageri Fm. These flat-lying Badami Group sediments preserve signature of fluvial to shallow marine tidal environment (Fig. A and B).

Lithology Pattern: 
Sandstone


Relationships and Distribution

Lower contact

Angular unconformity on Hoskatti Fm (uppermost formation of Kaladgi Gr) pelagic shale, overlain by Kerur Fm conglomerate at base of Badami Gr = Basement uplift, folding and a hiatus in deposition follow the first cycle (Kaladgi Gr) of sedimentation in the Kaladgi Basin.

Upper contact

Major unconformity; overlain by Deccan Traps Fm basalts (end-Cretaceous)
