摘　　要：The Dashuigou tellurium deposit found in 1991 in Shimian County, Sichuan Province of China, is the first and only independent tellurium deposit in the world. The deposit is located on the western margin of the Yangtze Platform. The tellurium ore bodies taking vein and lentiform shapes filled the N-S fractures in the pyrrhotite veins in hornblende schists at the northern limb of the Middle and Lower Triassic metamorphic arch. The main wallrock alterations are biotitization, sericitization, greisenization, dolomitization,
