| ELECTRON MICROPROBE | UNIVERSITY OF NEW MEXICO | JEOL 733 Superprobe equipped with a back-scattered electron detector, a thin-window energy dispersive spectrometer, and five WDS, all controlled by an Oxford eXL II analyzer system. Plagioclase analysis conditions: accelerating voltage of 15 kV, a beam current of 20 nA, and a beam diameter of 10 lm. A beam diameter of 10 lm minimized loss of vola- tile elements such as Na and K during feldspar analyses. OL & PX grains analyzed under the same conditions as plagioclase, except that the beam size 1 lm. |
