The rock magnetic properties of basalts are often useful indicators of suitability for use in palaeointensity experiments. The normal approach to sample selection is based on the use of a limited amount of rock magnetic data, possibly from only a single rock magnetic technique. This approach may result in the exclusion of otherwise suitable samples, or the inclusion of unsuitable samples. This study stresses the importance of analysing results from a number of rock magnetic techniques before selecting or rejecting samples for use in palaeointensity experiments. A new integrated rock magnetic method of sample selection or rejection is proposed, which uses the combined results from `thermal' (thermomagnetic and high-temperature susceptibility) and `non-thermal' (low-temperature susceptibility, hysteresis and alternating field demagnetisation) rock magnetic techniques to define `sets' of rock magnetic behaviour for Precambrian basalts, with a mixed grain size of pure magnetite. The behaviour of all samples in each `set', during both Thellier and Shaw palaeointensity experiments, is categorised, allowing a set of selection or rejection criteria to be defined. This new approach to sample selection or rejection for palaeointensity experiments has value for basalts of all ages, provided the sample collection is large enough and all available rock magnetic techniques are used.
