Ce and Nd isotopic data of rocks could give information on light-REE patterns of original sources of the rocks. In this paper, mathematical procedures of estimation of chondrite-normalized (La/Ce)N and (Nd/Sm)N values for the sources are presented in detail. Particularly, changes of (138La/142Ce)CHUR and (147Sm/144Nd)CHUR ratios with time are noted.
