圧縮火成岩を流れる正孔電荷キャリア Positive Holes Flowing through Stressed Igneous Rocks
Igneous rocks generally involve positive hole pairs (PHPs), a kind of lattice defects also known as peroxy links: O<sub>3</sub>X-OO-YO<sub>3</sub> with X, Y = Si<sup>4+</sup>, Al<sup>3+</sup> etc. When a portion of such a rock block is stressed or heated, PHPs are deformed and positive holes (p-holes) are activated. They are defect electrons corresponding to the O<sup>-</sup> electronic state in the O<sup>2-</sup> sublattice and can spread away into unstressed portion. Currents and positive surface electrifications detected in laboratory stressed igneous rocks can be explained by the p-holes. When the p-holes are activated in the Earth's crust accompanied with seismic or volcanic events, they would lead to anomalous electromagnetic phenomena and could affect our electronic communication.
