Summary The surface properties of soil carbonate were related to its distribution in thirteen profiles of a catenary sequence of calcareous soils from Azerbaijan. When carbonate surfaces were contaminated by Mg 2+ , 45 Ca was used as a tracer for Mg 2+ as well as Ca 2+ , thus enabling the carbonate surface areas to be estimated. These were shown to be inversely and curvilinearly related to soil carbonate contents, but with some abnormality for the three extremely saline/alkaline soils. Na+ does not appear to be specifically adsorbed on carbonate surfaces in the latter. The specific and the total surface areas of carbonate in the surface soils are very sensitive indices of profile development, and are combined with the content and particle‐size distribution of carbonate in the profiles to show the variation in soil development along the catenary sequence.
