Foraminifera from the carbonate cobbles and pebbles of Early Jurassic conglomerates of Franz Joseph Land as direct evidence of the existence of a Late Palaeozoic carbonate succession in the northeastern Barents Sea
Here we present the first description and images of foraminiferal fauna from the carbonate cobbles and pebbles of Early Jurassic polymictic conglomerates from Graham Bell Island, in the easternmost part of the Franz Joseph Land archipelago. The composition of the conglomerates suggests a proximal pr...
