"Jin Zhenmin, born in 1941, Wenzhou, Zhejiang people. China University of Geosciences (Wuhan) Earth Science College professor, doctoral tutor. Jin Zhenmin academician is a famous tectonic geologist in China, has long been committed to the upper mantle dynamics, rock rheology and high temperature and high pressure experimental research, and achieved outstanding academic achievements. The process of partial melting of the upper mantle to produce basaltic magma is one of the main motivations of plate motion and crustal hyperactivity dynamics. He found that the initial basaltic melt (3% to 5%) produced by partial melting of the upper mantle was stress-driven with large quantities of olivine minerals The grain boundary is formed by a melt film, which causes the mineral boundary to be wet, the coupling force is weakened, and the material diffusion and flow are accelerated. This finding is of great significance to elucidate the origin of the upper mantle low-velocity and high-conductivity (asthenosphere) and the heterogeneity of the continental orogenic belt. The results were published in the International Journal of Nature (1994) The cover of the magazine. The rheological constitutive equation of ultrahigh pressure eclogite is established, which provides experimental basis for revealing the mechanism of the disorientation of the lithosphere lithospheric lithospheric lithosphere in the continental collision orogenic belt. Deformation and study of the upper mantle lithosphere demolition has a direct significance. Based on the study of the dislocation microstructures of the mantle peridotite in 11 eastern China, it is proposed that the logarithmic normal distribution of olivine dislocation steady state sub - particles is the best microstructure parameter to estimate the upper mantle flow stress.
