Correction to: Flow‑through experiments on the interaction of sandstone with Ba‑rich fluids at geothermal conditionsPia Orywall1,2* , Kirsten Drüppel3, Dietmar Kuhn1, Thomas Kohl4, Michael Zimmermann5 and Elisabeth Eiche6Correction to:  Geotherm Energy (2017) 5:20  https://doi.org/10.1186/s40517‑017‑0079‑7After publication of the article (Orywall et al. 2017), it has been brought to our attention that there are a number of errors. The authors have listed them below.In the “Rock–mineralogical analysis” section, the 8-mm-thick layer is given with an incorrect unit. Instead, it should be 8 nm.In the “Flow-through rock; Precipitations of secondary mineral phases” section, the issues of the following sentences are incorrect:During investigation with SEM, some spherical structures were observed that only occur in some of the reacted samples (Figs.  18, 19) as small spheres with diameters of < 1 µm. They grew on the surfaces of sandstone minerals, also including the newly formed barite in the pore spaces. The article should instead read: “During investigation with SEM, some spherical structures were conspicuous, which only occur in some of the reacted samples (Figs. 18, 19) as small spheres with diameters of < 1 µm. They were observed on the surfaces of sandstone minerals, also including the newly formed barite in the pore spaces.”Additionally, the following sentence is incorrect: “Energy dispersive XRF measure-ments with the SEM reveal, that these phases consist of O (53.27 wt%), Si (30.12 wt%), and C (15.57 wt%).” It should instead read: “Energy dispersive X-ray measurements of these phases laying on an  SiO2-surface result in a distribution of O (53.27 wt%), Si (30.12 wt%), and C (15.57 wt%). The residue to 100% can be attributed to the sputtering materials Au and Pd.”For the following figures the legends need to be corrected:Figure 8 is a BSE image instead of an SE image.Figure  18: SEM (SE image) of barite with spherical phases in the surrounding area, sample 10.1 (20 °C/200 bar). Instead of: SEM (SE image) of barite covered with spheri-cal phases, sample 10.1 (20 °C/200 bar).Open Access© The Author(s) 2017.
