Results and Discussion
The present study shows that rock varnish sampled from various geomorphic
surfaces differs in the following characteristics:
1. Concentration limits of elements, which do not overlap each other. This tendency is most clearly pronounced for Mn, Fe and also for Si and AI, less clearly for AI, Ti, Mg, Ca.
2. Values of pairs and multiple correlation of elements. It has been established
that values of multiple correlation, both positive and negative, are higher as a
whole in rock-varnish samples from young levels, except for the pairs AI-Mg
with positive correlation and Mn-Si with negative correlation, which have a
