A new clinopyroxene-liquid barometer, and implications for magma storage pressures under Icelandic rift zones by D.A. Neave and K.D. Putirka (April, vol. 102, p. 777–794, 2017. Article http://dx.doi.org/10.2138/am-2017-5968. Erratum http://dx.doi.org/10.2138/am-2017-E1021232.)
In the Abstract and in the text, Equation 1 should have appeared as follows:
The key change is that in the last term, one should take the sum of the cation fractions of Na and K (not the product of the cation fractions, as unfortunately shown in the original text). The correct equation was used for all calculations presented in the manuscript; our results and interpretations thus remain unchanged. The spreadsheet accompanying the manuscript is also unaffected. We thank William Miller for bringing this error to our attention and we regret this error.
