... of the conductive zones is 9% 15% (Figs. 6B and 6C). In addition, natural seismic results show that the distribution area of high conductivity has a relatively high Poisson s ratio, and that there may be partial melting and intrusion of mafic materials in the upper mantle (Chen et al., 2017; Hao et al., 2023...
