Fig. 4: 27Al-NMR and 1H-NMR time-___domain data acquired from three anorthites from meteorite ABL 001, Arguin 002, and ON 001 under ambient conditions.

The blue lines represent real parts and the red lines the imaginary parts of the induced signal amplitudes. The signal amplitude Vsignal in the time ___domain is taken at t = 0; Vnoise was computed well with the range of stochastic thermal noise. Source data are provided as a Source Data file.
