在四个斑岩铜矿床露天采掘坑中,对99处各种岩石和各种类型蚀变带上,进行了157次相位和电阻率测量,并从这些地方取回岩样在室内进行了化学分析,研究其蚀变特征和矿化特征,还确定了其硫化物含量.所得结果总地讲,随硫化物含量的增高,电阻率值降低,相位滞后增大.测得的数据很分散,无法总结出有用的规律.但如果取其相位与电阻率的比值,则可以使数据的分散性减小.因此,在许多情况下,可以用相位与电阻率的比值来确定硫化物的含量.其数理基础如下. 百分频率效应(PFE)和金属传导因数(MCF)的
In the open pit pits of the four porphyry copper deposits, 157 phase and resistivity measurements were taken on 99 various rocks and various types of alteration zones, and rock samples were retrieved from these locations indoors Chemical analysis, the study of its alteration and mineralization characteristics, but also to determine the sulfide content of the results obtained generally speaking, with the increase of sulfide content, the resistivity value decreases, the phase lag increases. Measured data are scattered , Can not be summed up a useful law, but if you take the ratio of the phase and the resistivity, you can make the data less distributed.Therefore, in many cases, phase and resistivity ratio can be used to determine the sulfide content Its mathematical basis is as follows: Percent Frequency Effect (PFE) and Metal Conductance Factor (MCF)
