Ion probe analysis of artificially implanted ions in terrestrial samples and surface enhanced ions in lunar sample 76215,77

Zinner, E.; Walker, R. M.; Chaumont, J.; Dran, J. C. (Pergamon Press, 1976)

We used the ARL ion probe at the JSC to measure concentration depth profiles of artificially implanted ions in terrestrial minerals and of natural elements on the surface of a recently exposed lunar plagioclase crystal.
Nucleation and growth of plagioclase and the development of textures in a high-alumina basaltic melt

Nabelek, Peter I.; Taylor, Lawrence A.; Lofgren, Gary E. (Pergamon Press, 1978)

Dynamic crystallization experiments were conducted in order to determine the conditions necessary to produce poikilitic, intersertal and subophitic textures from a plagioclase-rich basaltic melt.
Surface concentrations of Mg, Ti, Fe and surface features in individual plagioclase crystals from lunar soil samples

Zinner, E.; Dust, S.; Chaumont, J.; Dran, J. C. (Pergamon Press, 1978)

Surface enhancements of Mg, Ti and Fe were measured with an ARL-IMMA and a CAMECA IMS-300 ion microprobe in 100-200 mesh plagioclase grains from eight different lunar soils. Enhancements of Mg, Ti and Fe were found in ...
