Following the code of stratigraphic nomenclature in India the metasedimentary sequence of the Kadana Reservoir area has been assigned to Lunavada Group, Based on lithological homogeneity, strike persistance and local relationship of superposition the rocks of the Lunavada Group have been separated into Wardia,Nahali, Bhawanpura, Chandanwara, Bhukia and Kadana formations in descending order of antiquity. The inliers of older metainorphics of Udaipur Group and associated ultramaf ics have been assigned to Vareth Formation and Rakhabdev Ultramafic Suite,respectively.
