Fig. S1. (a) Normalized IRM acquisition curves for the Lonar target basalts and their respective back-field IRM curves (in inset), (b) thermal demagnetization of SIRM spectra for the representative shocked basalt samples collected mostly from the crater rim and one from the downrange direction, (c-g) susceptibility versus temperature (χ-T) curves of representative Lonar unshocked [c] and shocked [d-g] basalt samples, and (h) Day plot of hysteresis (Day et al., 1977) of Lonar samples; dash curved lines are theoretical curves for mixtures of SD+MD grains and SD+SP grains after Dunlop (2002). SD, single-domain; PSD, psuedosingle-domain; MD, multi-domain; SP, superparamagnetic grains respectively; sample locations in figure 1b, for discussion see text.
Fig. S2. (a-e) χ-T curves of target basalt sample (A18/272°-0.92) in progressive heating-cooling runs; red line: heating run, blue line: cooling run; (f) ac field (~2 to 450 A/m) dependence of bulk susceptibility for the same representative specimen.
Fig. S3. Overall variations of NRM/χ of unshocked and shocked target basalt samples from around the Lonar crater; sample locations in figure 1b.
Fig. S4. (a) Stereographic projection of AMS susceptibility axes, and (b) P/ versus T plot of apparently unshocked target basalt samples from the far south of Lonar crater (A1/188o-4.04).
