Professor Mo Xuanxue has carried out innovative experimental research in the basic research field of magmatic thermodynamics. 1982, Lawrence national laboratory published the experimental results of partial molar volumes of the main components in the multicomponent silicate melt containing Fe2O3, and put forward the prediction model of the melt density containing Fe2O3 for the first time in the world. The estimation of magma oxygen fugacity at different depths (pressures) is of great scientific significance to magma mineralization and planetary evolution. This achievement has been highly praised by two American national reports, and has been cited by international famous magazines such as Nature, GCA and JGR11times.
The formation and evolution of the Qinghai-Tibet Plateau is one of the most concerned topics in international geosciences. Professor Mo Xuanxue used the theory and method of "rock probe" to make a long-term and systematic study on the tectonics-magmatism of the Qinghai-Tibet Plateau. The collision time between India and the Asian continent is a hot topic of international debate. It is quite different from the previous understanding of collision time (70-35 Ma). Through long-term research, Professor Mo Xuanxue put forward a new understanding that the India-subcontinent collision began at about 65Ma, and then established a systematic temporal and spatial framework of tectonic magmatic events in the Qinghai-Tibet Plateau, which attracted attention at home and abroad. The genesis of the extremely thick crust on the Qinghai-Tibet Plateau is one of the important issues in the study of continental dynamics. Mo Xuanxue put forward a new understanding of "two kinds of crust and two mechanisms" through the study of Cenozoic syn-collision and post-collision igneous rocks in Tibet. "Two types of crust" are newborn crust and recycled crust; The "two mechanisms", namely, the mechanism of tectonic compression and thickening and the mechanism of mantle material injection and their respective contribution rates are estimated. The latter mechanism is rarely involved in the previous literature; It is revealed that the collision volcanic activity on the Qinghai-Tibet Plateau tends to move to the periphery at any time, especially to the east. Combined with geophysical data, this may imply the lateral flow of crust and mantle materials in the deep plateau. Professor Mo Xuanxue's related papers in this field were cited by SCI publications for 6 13 times. Since 2005, he has been invited to give lectures at relevant international and national academic conferences for 25 times, and has been invited to write and review manuscripts for American GSA special volume and Lithos. Mo et al. (2006) was regarded by Y. Dilek (then editor-in-chief of GSA Bulletin) as "an important contribution to understanding the evolution of Cenozoic tectonic magma in Asia". In 2003, it was selected as the "First China 100 Most Influential Outstanding Academic Papers in China".
Professor Mo Xuanxue has been devoted to the research on the relationship between magmatism and mineralization in the Jinshajiang-Lancangjiang-Nujiang Tethys metallogenic domain for a long time, and put forward the theoretical summary and specific prospecting direction of "two metallogenic systems and three ore-controlling factors", which was adopted by the geological prospecting department and made a breakthrough in prospecting, contributing to the development of a new national mineral resource base in Sanjiang, and won the first prize of national scientific and technological progress in 2005.
