Kerur Fm
Lithology and Thickness
Conglomerate, red-brown sandstone, shale. Texturally and mineralogically mature sandstone of the Kerur Formation, popularly known as Temple Arenite, points to an environment where rate of sediment input was in balance with the rate of creation of accommodation.

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
Overlain by Katageri Fm

Depositional setting
Fluvial to tidal. Paleocurrent analysis of the Ramdurg Fm at base of the underlying Kaladgi Gr indicates northwest to westerly flow. However, during deposition of the Kerur Formation (Temple arenite) of the Badami Gr, the flow pattern changed a little with strong bimodality toward northeast and southwest indicating tidal activity, which played a major role in sorting and sculpturing the Temple arenite (Fig. A and B).
