Following publication of the original article (Mählmann et al., 2024), the authors identified an error in Fig. 9.

The incorrect Fig. is:

<figure><img src="image_4.png" /><figcaption>**Figure 9** The graph shows the stability ranges of clay minerals and facies indicative minerals correlating with the Kübler-Index (KI). The KI was chosen because all samples used (n = 1051) can be related to a KI-value. *Sm smectite, *Ism illite/smectite, *R reichweite*</figcaption></figure>
