Time-temperature modelling of the apatite fission-track samples from Seymour Island (Marambio and Seymour Island Groups) shows a similar thermal history style, involving a period of total thermal annealing and subsequent cooling (erosion/denudation). The samples were above 120C until about the Upper Triassic (220 – 210 Ma) age and then followed by the period of relatively quick Neogene and Quaternary exhumation (since ~30 – 40 Ma) to the present erosion surface.
