利用固体潮压电效应和自然电位测量勘查隐伏矿床的新方法

A New Method for Concealed Mineral Deposits Exploration by Using Body Tide Piezoelectric Effect and Spontaneous Potential Technique

介绍一个原始创新的地球物理勘探新方法(国家发明专利)。该方法利用压电效应的原理,将固体潮所产生的压电效应和自然电位测量结合起来,是直接勘探石英脉型金矿和其他矿床(有压电效应)的全新方法。其实施步骤如下:a)在勘查区域按网格布设不极化电极,埋植深度及要求与自然电位法勘查类似。b)对这些布设的电极进行二次电位测量:一次是在固体潮高潮时测量,另一次是在固体潮低潮时测量。根据固体潮产生的压电效应,在有石英脉型金矿(或方铅矿、铅锌矿、黄铁矿、铜镍硫化物矿及多种伟晶岩等)的地段将出现二次测量的明显差异,即高固体潮时和低固体潮时测量的电位差将有明显的异常。如果在该地段处没有预期的这些类型的矿床,高固体潮时和低固体潮时测量的电位差将不会有明显的异常。

A new original and innovative geophysical method（national patent） is introduced in this paper.The method uses the principle of the piezoelectric effect.It is a direct exploration method for quartz vein type gold deposits and other deposits（that have piezoelectric effects）,which combines the piezoelectric effect produced by body tide and the natural potential measurement.Its implementation steps are as follows：a） laying in nonpolarized-electrodes with grid in the exploration region,the implanted depth and requirements are similar with the exploration of natural potential method.b） measuring two times the natural potential,one is at the time of high tide,the other is at the time of low tide.According to the piezoelectric effect produced by solid tide,when there is a quartz vein type gold deposit（or galena,zinc,pyrite,copper-nickel sulfide ores and a variety of pegmatite,etc.,it will has obvious difference between the two measurements of high tide and low tide if there are no the expecting types of deposits,there will be no significant abnormalities between measurements of high tide and low tide
