摘要

Rare earth element and trace element of molybdenite in the Bangpu Mo （Cu） deposit, Maizhokunggar, Xizang （Tibet） , were analyzed by high sensitive inductively Coupled Plasma Mass Spectrometry in this paper. The results indicated that rare earth element in molybdenite had the distribution pattern of LREE enrichment and the fraetionation in both light rare earth element and heavy rare earth element were obvious. Eu and Ce negative anomalies exist in different degree in the molybdenite. The Eu negative anomaly in molybdenite maybe inherit the characteristics of Eu negative anomaly of the ore-forming fluid itself and the Ce negative anomaly reflected that the ore-forming fluid were of stronger oxidization property.
