Regions of the Kurama and Chatkal ranges of Eastern Uzbekistan, and the regions of South-Western Uzbekistan (Hissar Range) are considered, according to their cadmium contents of sphalerites in polymetallic ores (0.66 %, 0.30 % and 0.23 % respectively), to be cadmium-bearing provinces. Still higher, anomalous cadmium contents (3.8 %) have been found in sphalerites of polymetallic ores superimposed on the tungsten-molybdenum skarn mineralization of Western Uzbekistan. Here, in sphalerites of certain deposits (Inghichka) the cadmium content reaches 9.16 %, while the highest cadmium contents of sphalerites known to us from the world literature do not exceed 5 % (Czech Republic, Great Britain, Korea). Based on the above data, the region of Western Uzbekistan can be considered as a new cadmium province. As, otherwise, the metallogeny of this region is essentially characterized by skarn-rare metal (W-Mo) formation, our study shows that more attention should be paid to polymetallic mineralizations superimposed on the skarn-rare metal deposits.
