Hydro And Terrestrial Exploration Terrameter Measure Apparent Resistivity And IP
Apparent resistivity is a parameter used to reflect changes in the electrical conductivity of rocks and ores. In the case of uneven electrical distribution of underground rocks (two or more rocks or ores with different electrical conductivity) or uneven ground surface, the resistivity obtained according to the method and calculation formula of uniform level earth resistivity is called It is the apparent resistivity.
