The IR spectra of thaumasite–hielscherite series minerals: (1–2) hielscherite; (3–5) sulfite-bearing thaumasite. Samples are in order of decreasing SO3 content as follows: (1) G-3234, (2) G-3231, (3) G-3227, (4) G-3235, and (5) R-3240 (for chemical data see Table 2). The IR spectrum of sample Zb-01 is almost identical to that of G-3235 (4).
