Fig. 7From: Major to trace element imaging and analysis of iron age glasses using stage scanning in the analytical dual beam microscope (tandem)Stage scans depicting the Ca distribution in Broborg hillfort fragment where the pixel intensity is represented by gray level. A EDS image showing higher spatial resolution. B µXRF image showing large dynamic range contrast. Orange ellipse represents the residual apatite in mixed glass, dashed orange ellipse represents Ca-feldspar zone (milky inclusion-Fig. 1B), and light green ellipse represents the complex particle zoneBack to article page
