Typical Values for Rocks — Electromagnetic Geophysics
The conductivity/resistivity of a rock depends significantly on its mineralogy and pore-water properties. To demonstrate this, the conductivities and resistivities of water and certain rock forming minerals are provided. Fig. 14 Various conductivity values for
C1: Electrical resistivity of different soil and rock types
Overall resistivity is very sensitive to the geometry (distribution of the fluid). Factors that will DECREASE the resistivity of a rock: (a) Add more pore fluid (b) Increase the salinity of the pore fluid - more ions to conduct electricity (c) Fracture rock to create extra pathways for current flow (d) Add clay minerals
Why does resistivity vary for the same rock of different,
Resistivity of a rock solely depends on the mineral composition, porosity, water content and permeability. However, the same type of rocks with different

13-07-2018· Resistivity (ρ) & Conductivity (. σ. ) of Metals, Alloys, Rocks, and Soils. Resistivity, also referred to as specific resistance, is dependent on the nature of the material as well as its volume definition (shape and size). Resistivity is expressed in units that are the product of resistance and length; e.g., Ω·cm.
