Compositional zoning of fluid inclusions in the Archaean Junction gold deposit, Western Australia: a process of fluid � wall-rock interaction?

Polito, P A; Bone, Yvonne; Clarke, Jonathan; Mernagh, Terrence


The Junction gold deposit, in Western Australia, is an orogenic gold deposit hosted by a differentiated, iron-rich, tholeiitic dolerite still. Petrographic, microthermometric and laser Raman microprobe analyses of fluid inclusions from the Junction deposit indicate that three different vein systems formed at three distinct periods of geological time, and host four fluid-inclusion populations with a wide range of compositions in the H2O-CO2-CH4-NaCl± CaCl2 system. Pre-shearing, pre-gold,...[Show more]
