Abstract

The paper presents statistical calculations of the results of geochemical investigations of the primary and secondary dispersion haloes carried out on an area of some 40 km^2 in the Borov Dol - Shopur region (the Buchim ore district). Sampling was carried out on 500 x 200 spacing by research workers from IMGRE Moscow and the Buchim mine. The results obtained were first interpreted by the Geoscan method and the cluster analysis method (discussed in this paper), as well as the factor analysis of Kaiser method. Based on complex statistical calculations, correlation dependencies and classification of individual elements according to variogramas, factor distributions and dendograms, the types and geochemical associations distinguished are grouped us tollows: 1. Based on cluster analysis the following were distinguished: a) according to primary dispersion haloes (Pb, Zn, Sn). [(Ga, Ag) Vb]. (Ni, Co, Cr), [(Ti, Zr, Y) Nb]; b) according to secondary dispersion haloes [(Ni, Cr, Co) Mn]; [(Ti, V) Sc]; [(Vb, Nb) Ag]; (W, Ga); (Cu, Y) Mo; (Pb, Zn, Sn); 2. Based on data of factor analysis the following were distinguished: a) according to primary haloes [(Zr, Y. B, Ti) Nb]; (Sr); (Pb, Zn, Sn); (Ga, Ag, Vb); (B, Mn, Ni) Co, Cr b) according to secondary haloes: [(Ni, Cr. Co) Mn]; [(Vb, W, Nb) Ag, Ga)J; [(Ti, V) Sc)]; (Pb, Zn, Sn); (Cu, Y, Mo). Particular mention should be made of the (Pb, Zn, Sn) geochemical association which is clearly defined in both groups as well as (Cu, Y, Mo) as n characteristic association for the secondary dispersion haloes.
