Interesting scientific fact - high SP anomalies without redox process
(Shevnin V.A. Ryjov A.A. Kvon D.A. )
In different countries were discovered local self potential anomalies above 1200 mV that didn't related with red-ox processes in rocks. Such anomalies were found in mountains, they have inverse correlation with relief, underground water has low mineralization and high electrical resistivity. Possible cause of these anomalies can be electrokinetic or streaming potentials due to water filtration. Calculation of electric field intensity on Helmholtz formula shows that these anomalies could resulted at water resistivity above 100 Ohm-m at filtration in loose gravel-sand ground.......
