Deep marine slide and channel deposits from the Jurassic-Cretaceous Fossil Bluff Group, Alexander Island, Antarctica

The Fossil Bluff Grqup (FBG: ?Bathpnian-Albian) is the fill of a forearc basin which lay between the Antarctic Peninsula volcanic arc and an accretionary complex (LeMay Group) to the west (Figs 8.1 and 8.2). Volcanism in the arc, and accretion and deformation in the LeMay Group, were contemporaneous...

Description
Summary:The Fossil Bluff Grqup (FBG: ?Bathpnian-Albian) is the fill of a forearc basin which lay between the Antarctic Peninsula volcanic arc and an accretionary complex (LeMay Group) to the west (Figs 8.1 and 8.2). Volcanism in the arc, and accretion and deformation in the LeMay Group, were contemporaneous with sedimentation in the forearc basin. The basin was inverted during Late Cretaceous or Tertiary times during an episode of dextral transpressive deformation (Storey and Nell 1988). Tertiary igneous rocks in central and northern Alexander Island reflect arc migration, followed by Neogene extension.
