 (a) Trend of AFT ages with respect to their distance from the western Ross Sea coast along the Southern Ocean passive margin (○), and across the Transantarctic Mountains front from the Terra Nova Bay area to the Dry Valleys region (Ross Sea passive margin; □). The AFT ages abruptly increase west of the Rennick Graben (c. 300 km from the Ross Sea margin). A few older ages from the Transantarctic Mountains are an artefact of the high sample elevations. (b) Plot showing the relationship of AFT ages (± 2σ) v. elevation for vertical sample profiles from the USARP Mountains (○), the Morozumi Range (•), and the Dry Valleys–Terra Nova Bay area (□) (modified from Lisker 2002). It should be noted that within the last area the vast majority of AFT ages are younger than 100 Ma. Only a few samples from an altitude of >2 km have older ages. In contrast, samples from the USARP Mountains, west of the Rennick Graben, have generally older AFT ages. (Refer to Fig. 1 for sample location.) AFT data sources: Gleadow et al. (1984), Gleadow & Fitzgerald (1987), Fitzgerald & Gleadow (1988), Fitzgerald (1992), Balestrieri et al. (1994, 1997), Lisker (2002), Rossetti et al. (2003), and unpublished data.
