Education and Appointments:

MAO Ya-Jing, Ph.D., was born at Wenling, Zhejiang Province in 1985. He received his Ph.D. from the University of Chinese Academy of Sciences in 2014, became an associate professor at the Institute of Geology and Geophysics, Chinese Academy of Sciences in December 2018. His research focused on ore-forming processes of magmatic Ni-Cu deposits. Based on systematic petrology, mineralogy, and geochemistry work on Ni-Cu deposits in the Xinjiang and Jinchuan deposit in Gansu province, he revealed the characteristics and formation mechanism of high-nickel tenor deposits, demonstrated the relationship between oxygen fugacity of the Ni-Cu deposits in Central Asian Orogenic belts, and proposed the sulfide enrichment mechanism of the Jinchuan deposit was the result of sulfide liquid percolation in a crystal mush. He has served as a reviewer for several peer-reviewed journals and given oral presentations in international Ni-Cu (PGE) conferences.
