Geochemistry and provenance study of sediments from Krossfjorden and Kongsfjorden, Svalbard (Arctic Ocean)
Major, trace and rare earth element (REE) concentrations in combination with textural and mineralogical analysis of sediments have been used to understand geochemical fractionation in the sediment due to weathering and subsequent transport in the Svalbard region. Surface sediments from different wat...

Major, trace and rare earth element (REE) concentrations in combination with textural and mineralogical analysis of sediments have been used to understand geochemical fractionation in the sediment due to weathering and subsequent transport in the Svalbard region.

Bimodal distributions of grain size suggest that the finer size sediments were possibly deposited from the suspended load and coarser size from melting of sea ice and iceberg. Geochemical study reflects that the variation of chemical composition of the sediments is due to first order fractionations of elements during the grain size reduction and subsequent transport.
