This state-of-the-art review is a selective rather than an exhaustive survey of currently active areas in fine-particle rock magnetism. The topics considered are domain structure transitions, pseudo-single-domain mechanisms, diagnostic tests of domain structure, chemical, detrital, thermal and viscous magnetization processes, and magnetostatic interaction. Proposed future directions for research include: high-temperature thermoremanence and magnetic viscosity measurements and domain observations to examine the detailed magnetization blocking process; hysteretic~andthermal properties measurements and domain structure observations in the 0.25—1 ~sm(small multidomain) size range of magnetite for comparison with domain structure calculations; experimental calibration of the time or cooling-rate dependence of blocking temperature; and systematicstudy of the particle size, field and process dependencesof detrital and chemical remanences.
