From: Predicting sedimentary bedrock subsurface weathering fronts and weathering rates
Relative concentrations τi,j of the most weathering relevant elements and minerals. Titanium (upper right graph) is used as the “immobile element i” in the calculations. The vertical lines at τj = 0 separates the concentration values into losses (τj < 0) and gains (τj > 0) relative to the parent rock. τj = −1 indicates complete loss of j. Here a weathering zone (WZ) is defined as the interval between τj = −1 and 0, and weathering front is at τj = 0 (where τj value crossing the vertical line). The horizontal orange band marks the depth range of weathering fronts of the four PLM locations along the hillslope flow transect.
