sample_remark Cawood et al 2011 paraphrased: "The Halls Peak volcanics lies within the Tablelands phase [of the Gondwanide orogenesis]; characterised by widespread compressive deformation, metamorphism, the emplacement of S- and I-type granites, extension, and associated sedimentation. The Halls Peak volcanics have a well-established stratigraphic position close to the base of the Early Permian sequence in a section of the Barnard Basin. External features and internal structures of zircon grains from a sample of dacite are consistent with their origin in a felsic volcanic rock, including sharp multi-facetted outlines, small average size of the grains relative to intrusive bodies, and the presence of either very elongated grains with structureless or rounded and resorbed central parts surrounded by planar or oscillatory zoned outer parts."
