Pyrites consist of enriched Co, Ni, Cu, Zn, Pb, with enrichment coefficients higher than 2 and also comprise strongly depleted elements with enrichment coefficients less than 1, including Sr, Ba, Rb, and other large-ion lithophile elements, as well as high-field-strength elements (HFSE) such as Nb, Ta, Zr and Hf.

This fact is probably determined by soil particles transportation (in relation to lithophile elements), as well as the transfer of aerosols from Baikal lake, the waters of which contain high concentrations of Ca, Na, Mg, K, Si, and P.

The same is true for the Nb-anomaly as well as for ratios of large-ion lithophile elements (LILE) to light rare earth elements (LREE) and LILE to high-field strength elements (HFSE) (see [38] for the importance of these ratios for subduction processes).

The concentration of the following lithophile elements: Ba (300-1100 ppm), Cs (2-385 ppm), Hf (5-16 ppm), Sc (2.4-37.1 ppm), Th (1.1-15.5 ppm),and U (< 0.50-6.4 ppm) is remarkable.

They found that the large ion lithophile and light rare earth elements, especially K, Rb, Pb, Th, U, Zr and Nb correlated positively with terrigenous components, such as mica, rutile, tourmaline and zircon and with the maturity index of a sedimentary rock, while ferromagnesian elements Fe, Ti, Mn, Se and V and small cations Na, Ca and Sr correlates positively with chemically unstable components such as volcanic lithic, epidote and feldspar.

Uranium and thorium are lithophile elements, mostly concentrated in crystal rocks with an average Th/U ratio of 3.5 and are enriched especially in acidic igneous rocks such as granites, pegmatites as compared to basic and ultra basic intermediate [4-6].

An exception is a group of closely correlated lithophile elements, most specifically Al, Si, Ti, K, Rb, and Zr (less closely correlated Mg, Zn, Cu).
