Abstract
Summary
Frequently SP anomalies of DA origin considered as filtration anomalies that is case of false discovery. In nature DA anomalies are widespread while filtration anomalies are more rear. To distinguish these anomalies we should consider correlation of SP potential and apparent resistivity values along the same profile. In case of DA anomalies there is linear correlation between SP potential and logarithm of apparent resistivity. Some examples of SP anomalies are considered
