More work is required in South Victoria Land to further distinguish S- and I-type granitoids. Boundaries between these types elsewhere in the world are of fundamental tectonic importance. Detailed geochemical studies are however required in this respect. Further work on granites without taking this into account will only add further to the present confused nature of South Victoria Land basement studies. A future promising line of research stems from observations and preliminary sampling of the amphibolites within the Koettlitz Group. Study of immobile trace element concentrations may enable the pre-metamorphic tectonic characterisation of the unit in a manner analogous to Pearce and Cann, (1973) and Grapes and Palmer, (1984).
