文摘
- •
The spatial distribution of barite in undisturbed laminae from a palaeosol was determined using X-ray tomography.
- •
Barite occurs as an intricate vein network in a predominantly vertical direction.
- •
Vein networks follow the same topography of calcite and clay laminae.
- •
Evidence suggests barite precipitation post-dates or is contemporaneous with calcite deposition.
