Convergent margins are areas of geological complexity. Basins which occur in the same position relative to a volcanic arc may owe their origin to more than one process of formation.…Read more on Controls on sedimentation at convergent plate-margins

On the basis of geochemical signatures, Mesozoic magmatism in Antarctica is divided into the Ferrar Magmatic Province and the Dronning Maud Land Province. The tholeiitic magmatism of the Ferrar Magmatic…Read more on Coats Land dolerites and the generation of Antarctic continental flood basalts

This chapter describes the biology of living brachiopods. The Brachiopoda are significant components of the early Cambrian marine Faunas and are therefore one of the few phyla to be represented…1 January, 1992 by Jane Francis
Cretaceous sediments in the Antarctic have yielded diverse fossil floras, and a few occurrences of thin coal have been described. Their presence illustrates that the climate was favorable for plant…Read more on The potential for Cretaceous coal in Antarctica

The transcurrent Gastre Fault System in central Patagonia, which is closely associated with subvolcanic granite emplacement, is recognized as a major dextral shear-zone and geological boundary. We propose its equivalence…1 January, 1992
A combination of geochemical and field investigations of the Ballantrae Complex allows some control on the relative timing of events in its tectono-magmatic history. In particular, the presence of boninitic…1 January, 1992
In the West Antarctic sector of Gondwana, early stages of break-up are associated with the large Antarctic-Karoo-Tasman basalt province. Formation of this within-plate province was synchronous with active margin tectonics…1 January, 1992
Igneous rocks exposed in the southern Heritage Range include two diabasic sills (100 m and 300 m thick), three gabbroic stocks (outcrop areas each1 January, 1991
