This study reported for the first time the spinodal decomposition of supercritical fluid and the formation of magmatic network.Aguiar, A. Meanwhile, the spinodal decomposition of the integral decomposition mechanism will significantly contribute to the efficiency of the melt-fluid phase separation, which may have important implications for the formation of magmatic hydrothermal deposits. This kind of melt network can facilitate the simultaneously capture of silicate melts and aqueous fluids with different proportions when mineral crystallizations crystalize. As a free fluid or dissolved in silicate minerals, supercritical water greatly influences the structure. Here carbon dioxide is used as the mobile phase and other polar solvents such as methanol or isopropanol are used as co-solvents or modifiers 23. Water, the fluid of life at ambient pressure (P) and temperature (T), is mostly present under supercritical conditions in the Earth’s crust and mantle ( 1 ): that is, above the vapor-liquid critical point (647 K and 221 MPa). But when the temperature further dropped, the interfacial tension increasingly enlarged, leading to the disintegration of melt networks. Supercritical fluid chromatography has emerged as a powerful analytical tool due to its inherent flexibility and high throughput. Due to the difference of dynamic property between silicate and water, the silicate composition with a low relaxation could support the elastic stress and form a network of silicate melts in the fluids. In this study, we map the structure of the continental crust and mantle wedge in order to explore the presence of fluids and/or magmatic/intrusive bodies, and how they spatially correlate with. The experiment showed that besides regular nucleation-growth mechanism, supercritical fluid could be separated through spinodal decomposition. Ni's team observed the phase separation process of silicate-water system with the decreasing of temperature and pressure. Ni Huaiwei from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences found mechanism and the unmixing process of supercritical fluid. In a study published in Geochemical Perspectives Letters, a research team led by Prof. However, much remains to be done to reveal the evolution process of supercritical fluid because of the difficulties in experimenting. A physical description of supercritical fluids remains challenging because common approximations for solids and gases do not apply to liquids. Under the high temperature and pressure conditions deep in the Earth, silicate and fluids can be completely mixed, forging a supercritical geological fluid with the composition "thicker" than magmatic melts and "thinner" than aqueous liquids. We consider the flow of an inertial supercritical gravity current sustained by a constant source at x 0 and free drainage edge at x x D.
