The Ore deposit geochemistry is one of the dominant research fields of the Institute of Geochemistry, Chinese Academy of Sciences (IGCAS). The predecessor of the State Key Laboratory of Ore Deposit Geochemistry (SKLODG) is the Key Laboratory of Ore Deposit Geochemistry Chinese Academy of Sciences (KLODGCAS) which was established in 1989 on the basis of the Division for Studying Ore Deposits in IGCAS. The SKLODG was approved to be constructed in 2006 and verified by the Ministry of Science and Technology in 2009. The SKLODG and its predecessors have obtained a series of important achievements including First- and Second-class Prizes of China Natural Science Awards. It has relatively obvious advantages and features. It is one of important bases for high-level scientific research and personnel training in field of mineral resources in China.
