1160.3 Sunrise DAM 3D Geochem - Synchrotron XRF mapping - Published 02 Sep 2016
EBSDinterp is a GUI-based Matlab program to perform microstructurally constrained interpolation of electron backscatter diffraction (EBSD) datasets. The dataset in this collection comprises ASCII Cha... morennel Text Files (.ctf) of the raw and processed datasets used in the publication describing EBSDinterp. The dataset contains EBSD data of a large fractured albite aggregate filled with gold and pyrrhotite. This sample was collected from the Hamlet mine of the St Ives camp in Western Australia. Also included is the logfile written out by EBSDinterp on completion of the data interpolation that describes the parameters used in the interpolation of the dataset.less

Sunrise DAM 3D Geochem Stage 2 - Maia mapping - Published 15 Oct 2014
Chemical mapping (energy dispersive x-ray spectroscopy) data of replacement microstructures in carbonates from the Junction gold deposit near Kambalda in the Yilgarn Craton, Western Australia. Maps sh... moreow relationships between phases as calcite is replaced by dolomite and siderite. Included are the Bruker composite files that contain spectra for each point on the map, images of chemical maps for individual elements and composite RGB maps showing Mg, Fe, and Ca respectively. For composite images, chemistry is overlain on back scattered electron images to give the image the resolution of the BSE image but chemical data from the x-ray spectra.less

Maps show relationships between phases as calcite is replace... mored by dolomite and siderite. Collection contains .ctf (Channel Text Files) which are ASCII files with phase and orientation data as euler angles. Note that dolomite is indexed using the calcite match unit due to problems with systematic misindexing of dolomite.
Two files are included for each map with suffixes 'Raw' and 'Processed' to indicate the as collected and final published data respectively. less
