Abstract

This article examines the sediment provenance in the Shudu Lake basin, northwest Yunnan Province, China, as revealed by composite fingerprinting. Based on this technique, variations in the geochemical signature as¬sociated with lacustrine sediment deposits indicate that almost half of the total catchment sediment yield over an approximate 50-year period originated from channel banks. Conversely, the relative contributions of eroded sediment from both woodland and shrubland have generally remained stable over the period investigated, whereas the contribution of material from pasture has increased over recent decades
