Abstract
Cho Don-Cho Dien is a potential area for lead-zinc deposits with reserves of about 40% of Vietnam’s total lead-zinc ores. Most of the deposits are hidden. The results of geological structural analysis have shown that the lead-zinc mineralization here is mainly concentrated in terrigenous-carbonate sediments of Devonian age and closely related to late Permian-Triassic granite Phia Bioc complex. The paragenetic ores assosiations have been distinguished and a scheme of minerals formation has been designed. By the geochemical composition, lead-zinc ore consist of principal elements (Pb, Zn) and the accompanying elements (Mn, Fe, Cu, Cd, Bi, As, Ag, Sn, W, Sb). Statistical analysis has indicated that Pb has a strong positive correlation with Sb, a moderate correlation with Ag and a weak correlation with Sn and W. While Zn has strong, moderate and weak correlations with Cd, W and Cu, respectively. The presented data should be used for finding the hidden lead-zinc ore deposits in the Cho Don — Cho Dien area.
