- •
The Surat Basin's Walloon coals (Oxfordian) record peat accumulation under changing base level.
- •
The coals show a positive excursion in δ13C towards the top of the coal measures.
- •
This follows the global δ13C trend as recorded in marine carbonates from the same age interval.
- •
The positive excursion in δ13C corroborates a global climatic shift in the Mid-Oxfordian.
