Abstract：The Bangong Lake-Nujiang River metallogenic belt is an important copper-polymetallic ore belt in Tibet，and Garqiong is the key skarn-type copper-gold ore deposit in this metallogenic belt. With the means of sampling based on field geological investigation，microscopic examination，SEM observation，X-ray energy spectrum test and analysis，and systematic research on material components of ores，the authors found for the first time rare intermetallic compounds (Ni-Cr-Fe，Cu-Zn), and this was also the first discovery of such intermetallic compounds in the skarn deposit, as there had been no such reports both in China and abroad. These intermetallic compounds are all rare minerals in nature， formed in an unique environment, i.e., a strong reducing environment of hypoxia and low sulfur. The ore-forming elements with metallogenic specialization of mantle-derived magma were found in the skarn-type deposit for the first time, which has important scientific and academic significance for the study of metallogenic theory, ore-forming materials, metallogenic conditions, metallogenic environment and ore genesis.
