摘要：
Gold-rich porphyry-skarn deposits produce most tellurium resources, and the temporal and spatial distribution regularity of other types of tellurium resources needs to be discussed. In the national dynamic evaluation project of potential mineral resources, the features, type and spatiotemporal distribution of tellurium resource in China arc studied, the metallogenic regularities of tellurium deposits in China is summarized. This paper introduces the characteristics and problems of tellurium resource in China. Data of 45 tellurium deposits is collected, the tellurium deposits in China arc divided into six prediction types, namely alkaline intrusive rock type, carlin type, epithermal type, porphyry-skarn type, orogenic type and copper-nickel sulfide type. The metallogenic period of tellurium deposits in China is divided into Protcrozoic, Paleozoic, Mesozoic and Cenozoic. 9 tellurium metallogenic belts arc divided. The spatiotemporal distribution feature of each tellurium deposit type is summarized. 34 tellurium-related metallogenic series are determined and the metallogenic pedigree of tellurium deposits in China is established. The comprehensive study shows that tellurium ores in China are dominated by Late Paleozoic and Mesozoic epithermal, porphyry-skarn and copper-nickel sulfide deposits in the North and Northeast China, orogenic deposits in the Xiaoqinling-Xiongershan region, and porphyry-skarn and copper-nickel sulfide deposits in the middle and lower reaches of the Yangtze River and Yunnan-Sichuan-Guizhou regions. © 2023 Geological Society of China.
