The publisher apologies for an error introduced during production in the section of text on p. 10 under the heading “(v) The option that various structural variations within the samples could take place”, in paragraph six.
The published text reads:
“For possibility (b), the major celestines with the disregarded gypsum or anhydrite phases, the results in Supplementary Tables S10 and S16 demonstrate that there is a slightly different ratio between various crystallographic axes, such as c 0 < a 0 <b 0 (samples 1 and 4), a 0 < c 0 <b 0 (samples 2 and 3) and a 0 = c 0 < b 0 (sample 5).”
The text ‘possibility (b)’ should be changed to ‘possibility 2’, and hence the descriptor ‘the major celestines with the disregarded gypsum or anhydrite phases’ should be removed.
The correct text is:
“For possibility (2), the results in Supplementary Tables S10 and S16 demonstrate that there is a slightly different ratio between various crystallographic axes, such as c 0 < a 0 <b 0 (samples 1 and 4), a 0 < c 0 <b 0 (samples 2 and 3) and a 0 = c 0 < b 0 (sample 5).”
