Abstract

The paper presents an experiment on acoustic excitation of electromagnetic radiation (EMR) signals in skarn, sandstone, and magnetite ore samples. For the skarn and sandstone samples, the EMR signal amplitude was observed to decrease with increasing ultimate strength. Supposedly, this effect can be explained by assuming that EMR is generated when an acoustic wave propagates through an electrical double layer. The presence of piezoelectric inclusions (e.g., quartz) in the magnetite ore enhances the analog EMR signal and its spectral components.

岩石样品声激励产生的电磁辐射

在矽卡岩、砂岩和磁铁矿样品中进行了电磁辐射(EMR)信号的声激励实验。对于矽卡岩和砂岩样品，EMR信号幅度随极限强度的增加而减小。据推测，这种效应可以通过假设电磁波通过双电层传播时产生EMR来解释。磁铁矿中压电夹杂物(如石英)的存在增强了模拟EMR信号及其频谱成分。
