岩石压电性

本文介绍了岩石压电性的基本原理。在室内对几个典型的石英脉型矿床的岩石压电性进行了定性及定量的研究。通过实验证实了含石英岩石的压电性及压电效应的基本特征,计算了几个矿区岩石的压电模数。工作实践表明,研究岩石压电性,对寻找石英脉型矿床,以及建立新的地球物理方法均有重要意义,同时也有助于研究石英脉生成世代和定性评价石英脉含矿性等问题。

PIEZOELECTRICITY OF ROCKS

This paper describes basic principles of piezoelectricity of rocks. Qualitative and quantitative investigations were made in room on piezoelectricity of rocks from several typical quartz vein type deposits. Basic characteristics of piezoelectricity and piezoeffect of quartz-bearing rocks were verified through the test, and piezoelectric moduli of rocks from a few mining districts were calculated.Practice shows that the study on piezoelectricity of rocks are not only of great significance in prospecting for quartz vein type deposits and establishing new geophysical means, but also helpful in determining minerogenetic stages of quartz veins and evaluating qualitatively ore potentiality.
