Description :
This contribution focuses on the interpretation of REE patterns on a regional scale by comparing profiles from varios climatic zones and morphological positions. Under consideration of polyphase and polygenetic weathering processes, present REE distribution patterns are related to different phases of landscape and climatic evolution in SE-Bahia State, Brazil. Finally the use of REE patterns as tools for the reconstruction of landscape evolution and weathering history is discussed.
