- •
AND-2A core sedimentary clasts suggest a main source in the Beacon Supergroup.
- •
A potential supply from unexposed mixed siliciclastic-carbonate formations is also documented.
- •
Clasts assemblages include a variable content of intraformational clasts.
- •
Provenance analyses indicate two main scenarios differing in number of sources and most likely ice dynamics.
