What this study does
The paper applies independent component analysis to multielement μ-XRF records as a data-driven method for separating mixed geochemical signals into interpretable climate proxies.
Main finding
The extracted components resolve major late-glacial and Holocene hydroclimate changes, including transitions around the Bølling–Allerød, Younger Dryas and early-to-mid Holocene.
When this paper may be useful
- Extracting climate proxies from multivariate μXRF records
- Independent component analysis in sediment geochemistry
- Late-glacial and Holocene hydroclimate
- Data-driven proxy separation
