A method for determining one or more parameters of a rock sample, the method involving measuring the magnetic susceptibility of the sample, and determining a value of the parameter using that measured susceptibility. For example, the measured susceptibility can be used to determine the fractional content of one or two components of the sample. Preferably, pre-determined parameter information, such as permeability, is stored as a function of magnetic susceptibility (or a function thereof). Using this stored information, a parameter value for a sample under study can be determined, based on the measured magnetic susceptibility.
