Basin Research, Volume 37, Issue 3, May/June 2025.In this work we analyse the origin, transport, and deposition processes of pumice fragments up to 30 cm in size, deposited in the Northern Patagonian Foreland more than 200 km from the Andean volcanic arc. ABSTRACT There are numerous studies analysing volcaniclastic supply to continental environments in distal areas from source volcanoes.
