Abstract
Two methods were used in the prospection study of streams and recent alluvium in the western parts of the Kratovo-Zletovo volcanic area (BLEG and stream sediments). The research and samples analysis by the BLEG method determined gold content in all samples in the locality Borovic, within the range from 0.00031 to 0,248 ppm Au, and in the locality Plavica gold content ranged from 0.00047 to 0,0667 ppm Au. Examined and studied stream sediments from localities of the recent alluvium Borovic (Povišnica river) and Plavica localities determined characteristic geochemical associations of elements that were statistically processed that obtained appropriate groups of equivalent elements, which form cluster systems. Cluster analysis identified associations that can be divided into ore associations and associations originating from rocks, which built adjacent setting around the mineralization. From ore associations in the locality Borovic were determinated three element associations:{[(Y-Co)-(Ta-Nb)]-Ni}; {[(Sn-Pb)-S)-Ga]-Bi]}-[(Te-In)-Ag]-As-(U-Sb); {[(Cd-Zn)-(Au-Cu)]-(Ge-W)]}-(Fe-V)]}-{[(Mo-Hg)-(Pb-Sn)]-
(Re-Tl)-Se]}. From associations constituting petrogene minerals were allocated following associations: {[(Rb-K)-Li]-Cs}; {[(Zr-Hf)-Sr]-Ba-[(Y-Mg)-(Na-Be)]-(Ti-P)]}; [(La-Ce)-Hg]-Th. In the locality Plavica were determinated three elemental associations: [(Ni-Co)-Ca]; {[(Hg-Sb)-Ag]-Tl}-Mn-{[(Zn-Cd)-Pb]-[(Ge-Ga)-(Nb-Ta)]}; {[(W-Mo)-Re]-Au}-[(Cu-Fe)-Cr]-{[(Sn-As)-In]-Bi}-Te-[(Se-S)-U]}. From associations that build petrogene minerals were allocated four elemental associations: {[(La-Ce)-Th]-S}-(P-Ba); {[(Mn-Cs)-(Rb-K)]-Li}; [(Mg-Ca)-Na]; [(Hf-Zr)-Al]. These associations were sorted by level of relationship that exists between certain elements.
