Grain diameter distributions for each of the twelve sandstones sampled from exploration well EPS-1 at Soultz-sous-Forêts (Alsace, France): a Sample 84, b sample 100, c sample 157, d sample 198, e sample 248, f sample 299, g sample 347, h sample 402, i sample 453, j sample 497, k sample 508, l sample 540. The dashed red line indicates the average grain diameter. Mean mean grain diameter, min minimum grain diameter, max maximum grain diameter, sd standard deviation. Each graph is labelled with the box number, unit name, and sample depth
