The Gondwanian orogeny within the Antarctic Peninsula: a discussion
The relevance of the term “Gondwanian orogeny” to deformation within upper Paleozoic to Mesozoic rocks of the Antarctic Peninsula is reviewed, and the tectogenesis of deformation within this time frame is discussed. The term, originally applied by du Toit to deformation of middle Paleozoic to lower...

The relevance of the term “Gondwanian orogeny” to deformation within upper Paleozoic to Mesozoic rocks of the Antarctic Peninsula is reviewed, and the tectogenesis of deformation within this time frame is discussed.
