Abstract

The paper presents data on the distribution of chemical elements in the Pstan deposit area.

Analysis of the average contents and variances of chemical elements in boreholes along 9 cross-section lines revealed that elements such as Ni, Cu, Cr, and Zn exhibit content maxima coinciding with peak variance values, while Mn, Co, W, Ti, and to a lesser extent Nb and Y show distinct content minima with the lowest variance values. These patterns are observed along northeast-trending fracture zones where chrysoprase mineralization is exposed.
