Sedimentary and metamorphic geology of Campbell Island, Southwest Pacific Ocean.

Beggs, John McIntyre, 1953-

The sedimentary and metamorphic rocks of Campbell Island, 600km south of New Zealand, comprise a low-grade schist basement, very restricted in outcrop (the Complex Point Group), unconformably overlain by a 30m terrigenous clastic unit of late Cretaceous and Paleocene age (the Garden Cove Formation) which is in turn conformably overlain by up to 200m of Eocene and Oligocene partly chertified pelagic limestone (the Tucker Cove Limestone.) The youngest sedimentary rocks make up the Shoal Point Formation, which consists of up to 200m of pyroclastic sediments of late Miocene age, unconformably overlying the Tucker Cove Limestone.
Details of the stratigraphy, petrography, sedimentology and paleontnlogy of the above sequence are presented and the regional significance of parts of the study is discussed. A summary of the geological history of Campbell Island and the surrounding area is presented in the final chapter.
