Fig. 8. Magnetization versus distance from the peripheral impact glass spatter.

Shown are residual magnetization values for thermally demagnetized 15498 matrix glass subsamples after heating to 300°C. Individual subsample names are labeled. The gray shaded box denotes the zone likely to have been remagnetized by emplacement of the impact glass spatter (approximately three half-widths of the local glass spatter thickness).
