Fig. 3From: A multicomponent geothermometer for high-temperature basalt settingsSensitivity analysis of pH for sample K-28. The value was varied from 6.75 to 8.15 in increments of 0.1. The figure shows an extract of the data, where the pH value ranges from 7.55 to 8.15 in increments of 0.1. For pH 7.85, the statistical minimum of the boxplot comparison is reached; it is highlighted in a darker blue colourBack to article page
