Some Images and Maps from EPMA

X-ray Maps


High strength cement mortar. Sodium x-ray quantitative compositional map (background, interference corrected). Polygon delimited grid stage scan. 15 keV


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)


Monazite U-Pb-Th standard grain mount, automatic mosaic acquisition, BSE, 11mm x 11mm area


Monazite grain, false color with analysis position automatically registered to image, BSE, 15 keV


ZnO-SnO2 sintered powder sputter target, topographical/compositional backscatter image, 15 keV


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.
