Short summary
This is the first time that the electrical conductivity of gabbroic melt was assessed at high temperature and high pressure. The dependence of electrical conductivity on the degree of depolymerization was also explored. Electrical conductivity of gabbroic melts can be employed to interpret high-conductivity anomalies in the Mohns Ridge of the Arctic Ocean. This is of widespread interest to potential readers in high-pressure rock physics, solid geophysics, and deep Earth science.
