Outline of Final Research Achievements

The purpose of our study is to provide an explanation for experimental results on electrical conductivity variations for rhyolite melt. To detect melt processes using electrical conductivity, we carried out conductivity measurements on synthesized rhyolite. We also developed a cell-type lattice model to clarify the inter-connected conductivity mechanism of rock melt. We quantified electrical conduction networks in rock and evaluated electrical conductivity models of melt.
