Geomodelling of certain bauxite profiles from Kutch, Gujarat state, India

Bauxite deposits of Kutch occur in two different environments, viz. continental and marine, and hence it is of considerable interest from the points of view of genetic aspects, exploration and exploitation. Based on detailed exploration data some new softwares are developed to synthesise the geological and geochemical data. After studying the geostatistics, trend surface analysis has been carried out. With the aid of computer analysis and graphics, a geomodelling study has been attempted for the bauxite deposits that are derived from basalt (continental environment) and another one is presented which is associated with the marine environment. The significance of geomodelling study is substantially brought out.
