High Temperature Melting Curve of Basaltic Glass by Laser Flash Heating
文献摘要：
Basalt is an igneous rock originating from the cooling and solidification of magma and covers approximately 70％ of Earth's surface.Basaltic glass melting in the deep Earth is a fundamental subject of research for understanding geophysics,geochemistry,and geodynamic processes.In this study,we design a laser flash heating system using two-dimensional,four-color multi-wavelength imaging radiometry to measure the basaltic glass melting temperature under high pressure conditions in diamond anvil cells.Our experiment not only determines the temperature at the center of heating but also constructs a temperature distribution map for the surface heating area,and enables us to assess the temperature gradient.Through precise temperature measurements,we observe that the basaltic glass melting temperature is higher than those in previous reports,which is near the normal upper-mantle isotherm,approaching the hot geotherm.This suggests that basalt should not melt in most of the normal upper mantle and the basaltic melts could exist in some hot regions.
