Abstract

Gravelly floodplain deposits and 6 terrace treads in the Waimea Plains, northeast Southland, range in age from ca. 1000 years old to 350,000 yr old. Deposits are progressively more weathered with increasing parent material age. 2 phases of weathering are distinguished: a phase of approximate duration 100,000 yr in which most weathering and leaching occurs in the matrix, which becomes increasingly acidified; and a phase from 100,000 to 350,000 yr which is dominated by cation release from stones, reversal of the acidification trend, and breakdown of stone fabric
