Figure F1. Mössbauer spectra (dots) and mathematical simulations (lines) of a Site 1062 sediment sample from 94 mbsf, which was subsampled on board ship immediately after core retrieval. The spectra were recorded at (A) 77 K and (B) 0.3 K without application of a magnetic field. Solid lines running across the data points represent the mathematical sum of the subspectra inside.
