Effects of metal contamination on the activity and diversity of carabid beetles in an ancient Pb-Zn mining area at Plombières (B
      
Carabid beetles were monthly sampled with pitfall traps in the ancient Pb-Zn mining area of Plombières during one year.
      
Their occurrences can easily lead many people to compare them with the Pb-Zn deposit hosted in sedimentary rocks, such as Mississippian Valley-, Sedex- and sandstone-type Pb-Zn deposits.
      
The orebodies are clearly tectonically controlled without syngenetic features, which probably represents a new type of the sedimentary rock-hosted Pb-Zn deposit.
      
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.
      
Re-Os isotope dating of molybdenites in the Huangshaping Pb-Zn-W-Mo polymetallic deposit, Hunan Province, South China and its ge
      
The large-scale Huangshaping Pb-Zn-W-Mo polymetallic deposit is located in the central Nanling mineralization zone, South China.
      
All these ages demonstrate that the Huangshaping granite and related Pb-Zn-W-Mo deposit occurred in the middle Yanshanian period, when many other granitoid and related ore deposits emplaced and formed, e.g.
      
The mineralization associated with the granite includes W, Bi-Mo, Cu-Sn and Pb-Zn ores.
      
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.
      
Three zones can be recognized from the granite mass outwards: (1) Cu-Zn-Bi, (2) Sn, and (3) Fe-Pb-Zn-Cu.
      
Trace elements in galena and sphalerite and their geochemical significance in distinguishing the genetic types of Pb-Zn ore depo
      
This paper deals with the trace elements Ag, Sb, Bi in galens and Fe, Mn, Cd, Se, Te, Ga and In in sphalerite from 60 Pb-Zn deposits in China and other countries.
      
The contents of the selected trace elements and their ratios show regular variations from one type of Pb-Zn deposits to another.
      
The author considers that these diagrams are applicable to distinguishing the genetic types of Pb-Zn deposits.
      
Syngenetic sulfide ore beds associated with the Jiashengpan strata-bound Pb-Zn-S ore deposit are believed to have been precipitated under the conditions of pH varying from 7.08 to 7.17 and Eh from -0.232 to -0.418V.
      
Stratiform barite deposits (SB) and vein Pb-Zn barite deposits (VB) are known in a rift basin in central Guangxi.
      
Some pyroxenes from a Pb-Zn calcic-magnesia skarn deposit display an increase in Mn content.
      
Only Sn-W calcic skarn deposits and Pb-Zn calcic-magnesia skarn deposits contain garnets with more than 15 mol% (spessartine + almandine + pyrope).
