Lomas, Simon A.; Dingle, Richard V.. 1999 Possible evidence for Late Cretaceous off-axis volcanism in the outer James Ross Basin. Antarctic Science, 11 (03). 332-337. 10.1017/S0954102099000425
Abstract
A prominent volcaniclastic channel sandstone deposited by a landward-flowing sediment gravity flow is described from the Maastrichtian of Snow Hill Island in the northern Larsen Basin. The characteristics of this petrographically distinct event deposit appear to indicate a volcanic source to the east of Snow Hill Island, well away from the magmatic arc landmass which sourced the bulk of the Larsen Basin fill, suggesting minor off-axis intrabasinal volcanism in Maastrichtian to Paleogene times.
