Abstract
GIANT haloes1–3 attracted little attention until it seemed that those from Madagascar2 might be associated with superheavy elements4. Even though this association was not confirmed5, this renewed interest has generated several additional suggestions6 for giant-halo origin which will be evaluated elsewhere (R.V.G. et al. in preparation). We report here some new data on the giant haloes found in certain Swedish biotites1,2 and the implications which these data furnish for a radioactive origin of the enigmatic dwarf haloes.
