Abstract

The Woodlawn Zn-Pb-Cu deposit in the SE part of the Paleozoic Lachlan orogen comprises three main west-dipping lenses hosted by Late Silurian volcanics of the Murruin sub-basin of the Ngunawal basin. This paper emphasizes the structural setting of the deposit and presents results from a mesoscopic and microscopic study of a newly discovered lens of sulfide that is controlled by a thrust system and which contains syntectonic and post-tectonic mineralization overprinting layered (bedded?) sphalerite-chert rock. The structural control on position, the shape of this lens, and the late nature of much of its contained mineralization lie at odds with previous interpretations of Woodlawn as a purely volcanogenic massive sulfide deposit. -from Authors
