- •
87Sr/86Sr and 143Nd/144Nd ratios can help characterize subglacial sediment transport.
- •
High variability in εNd values may relate to climatic disturbances.
- •
Direct relationship between Rb/Sr and 87Sr/86Sr values helps track incongruent weathering.
- •
Trends may be detected using 87Sr/86Sr post-comminution ages.
- •
Weathering patterns partially controlled by mantling of bedrock.
