Lithology and Thickness

Clayey sandstone. This formation consists of predominately grey, medium- and fine-grained sandstone with thin beds of grey to dark grey clay and Limestone towards the top part. In CH-1-1, Kasargad Fm consists of argillaceous limestone, sandstone and shales in the upper part two thin basaltic flows were observed in the basal part of this formation in CH-1-1.
