R. Bontognali, Judith A. McKenzie, Rolf J. Warthmann and Crisogono Vasconcelos published in Terra Nova, 26, 72–77, 2014. The Editors of Terra Nova and the authors of the above article would like to draw the reader's attention to an error in Figure 4B. The label ‘20’ on the horizontal axis was misplaced, making it difficult to precisely measure the positions of the peaks shown in the figure. In the corrected figure, the position of the XRD spectra have been precisely aligned with respect to the main peak of the internal quartz standard. The corrected figure and its caption are reproduced below. Figure 4Open in figure viewerPowerPoint X-ray diffractograms of the carbonate precipitated in the presence of EPS, showing that no major crystallographic difference exists between the minerals formed with (Experiment B) and without (Experiment A) metabolizing microbes. The main peaks corresponding to the minerals are indicated as follows: high Mg-calcite (hmc), Mg-calcite (mc), Ca-dolomite (cd), quartz (q). Quartz powder was added as an internal standard. (A) Comparison between bulk precipitates collected from Experiments A and B after an incubation time of 30 days at 30°C. In both cases, the mineralogy corresponds to a solid solution of high Mg-calcite and disordered Ca-dolomite. (B) After a longer incubation time (i.e., about 16 months), both solid solutions evolve into two distinctive mineral phases consisting of Mg-calcite with less than 5 mol.% Mg2+ and disordered Ca-dolomite with more than 40 mol% Mg2+. The authors apologise for this error and any confusion it may have caused. Reference Bontognali, T.R.R., McKenzie, J.A., Warthmann, R.J. and Vasconcelos, C., 2014.
