Determine relative gain and loss of elements associated with weathering of basalt to a tropical Alfisol Bhorizon (Plate 13). Use the data provided to rank elements in terms of % change as well as by calculating the mass transfer coefficient, j , for each element.

For both methods, rank elements in terms of mobility, and compare results produced by the two methods

3. Determine relative gain and loss of elements associated with weathering of basalt to a tropical Alfisol B-horizon (Plate 13). Use the data provided to rank elements in terms of % change as well as by calculating the mass transfer coefficient, tj, for each element. Major elements are presented as wt% oxides and trace elements as mg kg' (ppm). This dataset pertains to question 9.7 and is from the B-horizon and underlying basalt parent material shown in Plate 13.
