Description :
The AA. examined the geochemistry and micromorphology of the soils on a suite of morphologically well-defined and visually distinct fluvial terraces, up to 40 m elevation above the current riverbed, at Thangbi in the upper Bumthang Valley, Bhutan. The soils are interpreted mainly as a monoclinal post-incisive chronosequence. The overall impression is of limited pedogenesis, even in the soils on the higher terraces. The AA. examine possibilities that the immaturity of the soils is due to pedogenic rejuvenation by post-incision additions to the soil parent materials.
