About this Collection

Junction Deposit Carbonate Study EBSD


Electron back scatter diffraction data of carbonates from the Junction gold deposit near Kambalda in the Yilgarn Craton, Western Australia. Maps show relationships between phases as calcite is replaced by dolomite and siderite. Collection contains .ctf (Channel Text Files) which are ASCII files with phase and orientation data as euler angles. Note ... more

electron back scatter diffraction EBSD calcite siderite dolomite replacement topotactic


Raw data are exported from Bruker Esprit 9.4 software that was originally used to acquire the datasets. Original Bruker datasets included energy dispersive x-ray spectra for each point and these were used to distinguish calcite and siderite. The data was collected from sample 250 as described in Polito et al. (2001), Australian Journal of Earth Sciences, 48, 833 - 855


The data was 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
