Provenance of individual FT zircons and apatites ages varies in wide spread of Carboniferous to Early Paleogene ages between ~60 to ~350 Ma. Jurassic-Cretaceous ages of northwest James Ross Island are probably compatible with derivation of sediment from western lying Mt. Reece and Mt. Bradley region, where the rocks of the Antarctic Peninsula batholith appears. Sediments from Seymour Island are probably originating from Trinity Peninsula Group and Antarctic Peninsula Volcanic Group. Shortening of tracks was due to subsequent volcanic/magmatic activity before transport of rocks and deposition into the James Ross Basin or alternatively, due to volcanic reheating after deposition.
