Inhoud:
Aluminous, mafic, felsic, calcareous, and sulphide-rich rocks have been involved in localized deformation and retrograde metamorphism at Broken Hill, western New South Wales, where retrograde schist-zones intersect high-grade, regional metamorphic rocks of the lower granulite facies (or the amphibolite-granulite facies transition). Although technically retrograde, the schists contain mineral assemblages indicative of the lower amphibolite facies. The schist-zones were formed by local folding, apparently as part of the third stage of deformation in the Broken Hill area.
