Description :
The geochemical, mineralogical and lithological composition of modern stream bed material is examined in order to characterize sources and evaluate downstream mixing of sediments in the upper Fraser River drainage basin. The lacustrine and alluvial sedimentary records of the upper Fraser River watershed are the subject of ongoing palaeoenvironmental investigation and have pointed toward pronounced variations in glaciation in the drainage basin over Holocene time scales. The focus of this study is therefore on discriminating glacial and non-glacial source areas and sediments so they may be identified in the palaeodepositional record.
