It is concluded that the Cu-Pb-Zn mineralizations in the Dajing and Caijiaying deposits resulted from the identical tectono-thermal event of magma-fluids induced by Mesozoic tectonic transition and extension in the eastern part of North China Craton.
      
The strata-bound Cu-Pb-Zn polymetallic sulfide deposits occur in metamorphic rocks of greenschist phase of the middle-upper Proterozoic Langshan Group in central Inner Mongolia.
      
Six zones may be recognized from the granite mass outwards: (1) Nb-Ta-(Li-Be-Mo), (2) Sn, (3) W-(Sn), (4) Cu-Pb-Zn-(Bi), (5) Sb-Hg, and (6) Au-Ag.
      
Stratiform Cu-Pb-Zn (-Au-Ag) mineralization associated with black carbonaceous schists and acid metatuffs is restricted to distinct horizons within the Cretaceous sequence of the Diahot region.
      
Based on the fluid inclusion "gas" signature for the Carrock Fell deposit, a distinction can be made between potentially tungstaniferous quartz veins and those related to Cu-Pb-Zn deposits in the absence of diagnostic ore minerals.
      
In the lower part of a pre-Caradocian series associated with volcanics there are disseminations and lenses of arsenopyrite and pyrite with gold and Bi-Ag-Cu-Pb-Zn-W minerals.
      
The chemistry and origin of zincian spinel associated with the Aggeneys Cu-Pb-Zn-Ag deposits, Namaqualand, South Africa
      
Besides the formation of extensional quartz-stibnite-Pb-sulfosalt veins, the mineralising, low-salinity NaCl-KCl-rich high-temperature tectonic brines have overprinted sulfide assemblages within earlier siderite-(Cu)-Pb-Zn veins.
      
In contrast with the earlier siderite-(Cu)-Pb-Zn veins, neither the quartz-stibnite-sulfosalt nor the (Cu)-Pb-Sb sulfosalt assemblages were affected by Variscan deformation.
      
The displaced/allochthonous nature of the Ofoten Cu-Pb-Zn 'metallogenetic province' would explain the enigmatically high concentration of small-scale Cu-Pb-Zn deposits that occur only in this particular area of the Norwegian Caledonides.
      
In northern Banat, Fe-Cu-Pb-Zn skarns occur whereas in southern Banat, porphyry-style copper and molybdenum deposits predominate.
      
The Cu-Pb-Zn orebodies are hosted by carbonate rocks and the mine waters are supersaturated with respect to calcite and CO2.
      
Chemical analyses showed an As-Cu-Pb-Zn association related with the mineralisation of the Iberian Pyrite Belt.
      
Diese Metalle sind in der Reihenfolge Cu-Pb-Zn an drei bestimmte Zonen um die ?Rote F?ule? gebunden.
      
A thermal neutron activation method has been developed for the determination of Cu in Cu-Pb-Zn ores and chalcopyrite ore concentrates using the reaction63Cu(N, γ)64Cu.
      
The district contains a number of silver-bearing Fe-Cu-Pb-Zn mineral deposits near igneous complexes and Fe→Cu→Pb→Zn zones away from the complexes.
