Thank you Kev for an excellent series of images and the description, I am now better informed.
I am confused however about the definition of "ohm-meters". In electrical and electronic engineering terminology a unit of one ohm is just called an 1-ohm. Being equal to volts/amps.
Does the term ohm-meters, in geological terms, actually mean ohms per meter (distance) which would make sense to me.
Also you say the "Argentinean Projects have resistivity of ~0 ohm-meters (even negative in some cases). " the value of 'resistance'
V/A cannot have a negative value at least not in the contex that I understand.
Maybe the science of geology has it's own special definition for electrical conductivity.
