  abstract = {{T}he current soil dynamics of a podzol-oxisol climosequence located in {T}ahiti on basaltic and pyroclastic parent rocks has been investigated using the "test-mineral" technique. {T}he test-mineral, a vermiculite with a high exchange capacity (161 meq/100 g) was placed in recoverable bags in the {A} and {B} horizons of three members of the sequence, for periods of 1 to 3.5 years. {C}hanges in the chemistry and mineralogy, enabling complexing acid environments to be distinguished from non-complexing, were determined following the in situ reaction with natural soil leachates. {A} set of leachates from the same horizons were collected and chemically analysed at the end of 3.5 years. {T}he results indicate that the current acid environment is only weakly complexing. {T}his suggests that the podzolisation processes which led to the development of a unique {A}2 horizon containing gibbsite, anatase and rutile, and a placic horizon, in the upper podzol member of the sequence, is no longer operating.
