Junction Deposit Carbonate Study Images


Images of replacement microstructures in carbonates from the Junction gold deposit near Kambalda in the Yilgarn Craton, Western Australia. Images show relationships between phases as calcite is replaced by dolomite and siderite. Included are the raw images as well as a full sized stitched version, a reduced resolution stitched image and a contrast ... more

Data were collected and stitched using the Bruker Esprit software. The phases in the contrast adjusted image were separated, adjusted and restitched using GIMP 2. The data were collected from sample 250 as described in Polito et al. (2001), Australian Journal of Earth Sciences, 48, 833 - 855


The data were collected and processed by Mark Pearce

About this Project

Gold Research


Examining the relationship between damage and chemical reaction fronts around gold deposits. The project combines microstructural and microchemical analysis techniques to examine in detail the relationship between deformation and alteration and how these relate to gold mineralisation


Rob Hough


Imaging of chemical variations during replacement reactions


Quantitative and qualitative imaging and chemical mapping was carried out to complement crystallographic studies of mineral replacement reactions from ore bodies.
