Clay crustal dating environment in isotope tracing

Despite considerable interest in the Arctic Ocean, the circum-Arctic source regions are poorly characterised in terms of their Sr and Nd isotopic compositions.
In this study we present Sr and Nd isotope data from the Paleogene Central Basin sediments of Svalbard, including the first published data of stream suspended sediments from Svalbard.
The stream suspended sediments exhibit considerable isotopic variation ( 0.73421 to 0.74704) which can be related to the depositional history of the sedimentary formations from which they are derived.
The sample is, however, coated with a glass splash, consistent with impact melting of the rock. The is to produce the highest quality isotope data, to innovate in techniques development and applications, to train students and visitors in the techniques involved in gathering such data, and to maintain itself as a world-class isotope measurement facility.
