CePO4 single crystal (Oak Ridge, flux grown), Pb elemental quantitative composition, polygon delimited area grid.
High strength concrete, Na elemental quantitative compositional map, mosaic combined stage and beam scan, 15 keV
Backscatter Electron Images (BSE)
1 cm x 1 cm mosaic image of Acapulco meteorite, BSE, 15 keV (4096 x 4096 pixels)

Other Images (CL)
Ti concentrations in quartz veins overlaid on a coordinate registered CL image. Note the dark CL bands correspond to Ti concentrations in the 20 to 60 PPM levels.
