Fig. 8From: Magmatic–hydrothermal system of Aso Volcano, Japan, inferred from electrical resistivity structuresLog data for well sites W1 and W2, the locations of which are shown in Fig. 1. Stratigraphic section (left), vertical distribution of resistivity (center), and temperature (right). The red lines in the center diagram for each well site show the vertical distribution of resistivity from the final model at the well site, and the solid black lines show the corresponding electrical log data. The shaded intervals in the post-caldera volcanic products in the left diagram for each well site show the positions of formations that contain abundant montmorillonite (alteration product). The depth values are BSLBack to article page
