suits are very near to this value, as Mn-content of the soils of the investigated area ranges between 250 and 2 000 ppm, and mostly ranges between 800 and 1 300 ppm. The southern part shows relatively higher Mn-content. Within the profiles generally level B contains the most Mn, while A and C levels contain more or less equal quantities. Copper Concentration of copper in the soils ranges from almost nil to 200 ppm, in the temperate climate zone is between 15 and 40 ppm. Our area is characterized by 10 to 25 ppm Cu concentration, ranging mostly within 10 and 16 ppm. Regularities of concentration changes within the profiles could not be determined with this method. Zinc_ Concentration of zinc in the soils ranges between 20 and 600 ppm, in the temperate climate zone mostly between 20 and 70 ppm. Generally soils with higher carbonate content contain more, while sandy soils less zinc. The investigated area shows less than 80 ppm zinc concentration, mostly ranging within the 40-60 ppm interval. The profiles show higher concentrations in the upper levels than in level C. It is attributed to its geochemical character of being more enriched in the humous levels. Lead Lead content of the soils may range from trace quantities up to 1 200 ppm, in the temperate zone it ranges between 20 and 50 ppm. Our area shows less than 25 ppm lead concentration, mostly within 13 and 16 ppm. Generally it can be observed that in the upper levels its concentration is higher and it decreases downwards. GaBi_um_ Gallium content of the soils ranges between 5 and 300 ppm, in the temperate climate zone mostly within 20-50 ppm. Our area contains 6 to 2 5 ppm Ga, mostly 10-16 ppm Ga.This value is somewhat smaller than the average one. Most Ga occurs in the B level, least gallium in the C level. Extremely small values are shown in the uppermost (0-20 cm) level. Cobalt_ Cobalt content of the soils ranges between 0. 05-300 ppm, in temperate climate zones between 0.5-20 ppm. The investigated area contains less than 25 ppm cobalt and is generally below the 16 ppm sensibility limit, although its spectral line is observable on the photographic plate. Its quantity is estimated to be 10-16 ppm. This value is very similar to the average value. Since the quantity of cobalt lies around the sensibility limit of the analytical method, it cannot be used for correlation among profiles. Ni_ckel_ Nickel content of the soils ranges from trace quantities to 500 ppm, in the temperate climate zone between 10-80 ppm. The investigated area contains less than 60 ppm Ni, mostly 16 to 40 ppm. Distribution in the profiles is very variable. In the uppermost 20 cm its quantity is much less than below. Its maximum is reached in level B and in the upper part in level C. However, in profile 29 (alluvial meadow soil) concentration increases with depth. Concentration of nickel and cobalt changes together due to their geochemical relationship. Chrjsmium Chromium content of the soils ranges from 10 to 4 000 ppm, in the temperate climate zone from 50 to 200 ppm. The investigated area is characterized by 16-160 ppm chromium concentration, mostly 60- 100 ppm. In profile 29 (alluvial meadow soil) rises to 130-160 ppm. Chromium is enriched in level A, its concentration decreases or does not change with depth. Titanium Ti-content of the soils is 100-10 000 ppm, in the temperate climatic zone 1 000 ppm.
