Abstract: The content and distribution of 37 chemical elements in rocks, soils and wood of old-aged pines of the Belebey plateau-like elevation have been studied. It is shown that soils have a low and very low level of availability of the elements studied. Their absorption by pine trees is largely derived from the soil-forming rock, Zn, Sc, Co, W, Sb, Cr and As are the maximum accumulation (the biophilicity coefficient is 1.17-0.60). From the soil, pine absorbs Mo, Zn, Sb, Sr and Pb most intensely (the biophilicity coefficient is 1.09-0.14) and very weakly Be, Ba, W and V (the biophilicity coefficient is 0.03-0.01). Rare-earth elements are almost equally absorbed from the soil and more selectively from the rock. Eu, Nd, Sm and Pr are accumulated to a greater extent and much less Cs, Lu, Er and Tm. The uranium content in soil and rock is almost 6 times greater than thorium but its biological absorption by pines is much lower.
