Abstract
Tertiary carbonates from Kutch have been analysed for chemical constituents such as Ca, Mg, Mn, Fe, Sr, Ba and insoluble residue. Vertical distribution of these elements shows a gradual decrease in Ca and Sr and increase in Mn, Fe, Ba and insoluble residue from older to younger beds. R-mode factor analysis of chemical data is interpreted. The first factor loaded on IR-Mn-Fe-Ba is considered to be the effect of clastic deposition, chemical co-precipitation and adsorption by clay minerals. The second factor loaded on Ca, Sr, Ba and Mg explains their syndeposition, leading to the formation of limestones.
