In the Iron Ore Ranges of Bihar and Orissa, three erosion surfaces have been recognised around 3000-2700 feet, 2300-2000 feet and 1600-1400 feet above M.S.L., based on model studies in the laboratory, and the relative positions in the field of the residual deposits of laterites and lateritic iron and manganese ores. These have been correlated with those in the neighbouring areas in the southeastern Chota Nagpur and the Simlipal massif in Bihar and Orissa respectively. Based on the study of sedimentary record in the adjoining Bengal Basin, the tentative ages assigned to them from the top are Upper Jurassic to Lower Cretaceous, Upper Eocene and Upper Miocene.

Bauxite cappings occur discontinuously, along a linear stretch amidst the Eastern Ghuts comprising khondalite and charnockite groups of rocks, in the States of Andhra Pradesh and Orissa. These cappings/deposits, by virtue of their proximity to the eastern coastline of India, are christened as the East Coast Bauxite deposits.The East Coast Bauxites of Andhra Pradesh include the Anantagiri, Chintapalli, Gurtedu and Paderu groups of deposits. The Anantagiri group comprises Galikonda, Chittamgondi, Raktakonda and Kutuki deposits. The Chittamgondi bauxite deposit, charucterised by multi-directional slopes, is preserved in a sickle shaped synformal structure. Furthermore, the maximum thickness of bauxite, viz., 54 m, amongst the East Coast Bauxite deposits, investigated so far, has been recorded in it. As has already been established for other East Coast Bauxite deposits, the geomorphological setup and morphometry have played a pivotal role in the formation of the Chittamgondi bauxite deposit.
