AbstractPhysical properties (density, magnetic susceptibility, electrical resistivity, porosity, formation factor, surface resistivity) were measured on 26 Canadian kimberlite samples for information required in exploration of kimberlite-hosted diamond deposits. Following previous studies on fewer samples and parameters, this paper provides a more complete set of measurements to link geophysical parameters to geological characteristics. Results suggest that porosity is a major factor controlling density, formation factor and electrical resistivity of these kimberlites, with additional factors of significance influencing resistivity. There are indications of porous kimberlites being altered, and nonporous ones being fresh. Magnetic susceptibilities seem unrelated to other parameters. Archie's coefficients may show characteristics unique to kimberlites. This is primarily a documentation of physical properties of some kimberlite samples. Continuing studies on quantitative relationships between mineralogy (primary and secondary), petrographic textural type (crater, diatreme, or hypabyssal facies), and physical properties are expected to provide geophysical signatures unique to kimberlites.
