Jul 02, 2020 The Pb-Zn district of the PAZ was exploited in twentieth century. It has produced ca. 400 kt of Zn and 180 kt of Pb (BRGM 1984; Ovejero Zappino 1991).Three types of Pb-Zn mineralization are described in Cugerone et al. ().Type 1 is minor, disseminated, and laminated mineralization, probably associated to sedimentation during Cambro-Ordovician and Devonian times (Fig. 1c).
Porphyry Cu systems presently supply nearly three-quar-ters of the world’s Cu, half the Mo, perhaps one-fifth of the Au, most of the Re, and minor amounts of other metals (Ag, Pd, Te, Se, Bi, Zn, and Pb). The systems also contain major resources of these metals as well as including the world’s

In contrast, others such as the Coeur d'Alene Ag-Pb-Zn veins, or the massive Zn-Mn-Fe oxide/silicate bodies at Franklin and Sterling Hill, or the Cu-U-Au at Olympic Dam, or the Cu-Zn-Pb-Ge ores of Kipushi and the Tsumeb pipe remain genetic enigmas despite, in the instances of the first two, extensive research spanning many years.

Many of the banded ores show kinks, swirls, and folds indicative of post-deposition deformation (Schmidt, 1978). The ore bodies are lenticular in form, and the long axes plunge down dip or steeply to the north or south. Ore bodies showed pronounced elongation with length:breadth ratios ranging from 2:1 to 5L:1 and averaging 3:1 (Schmidt, 1978).

Jul 14, 2015 Concentrations of Ag, Au, Cu and Zn were determined via neutron activation analysis in ore prospecting samples from the Cozamin and Tizapa Mexican mines. Ag concentrations were determined by applying cyclic epithermal neutron activation analysis. The method combined with an automated fast-pneumatic transfer system allows increased sample through-put which improves the …
