Electron microprobe trace element data apatite and rutile, Zambian Copperbelt
type: Dataset
description: Trace element geochemistry, using Electron Microprobe Analyses, of rutile and apatite from the Zambian Copperbelt, includes standards, and accuracy and precision. Apatite grains from Arkose , Kitwe and Mindola Clastics Formations, Nchanga were analysed using a JEOL JXA-8530F Plus hyperprobe electron microprobe at the NHM, London. Spot locations were chosen away from any pits or inclusions. Most apatite crystals received two spots; one located close to the core and one close to the rim in order to assess compositional zoning and intra-grain heterogeneity. The elements P, Ca, F, Cl, Na, S, Sr, Fe, La, Ce, Mn, Si, Mg and Ti were measured. F, Sr, Cl, P and Ca were measured first in analytical sequence as suggested by Goldoff et al., (2012) to minimise time-dependent x-ray count variations. For rutile, 14 elements were measured across the 5 WDS detectors under the same operating conditions as for apatite. These elements were Si, Al, Mg, Ca, Ti, Nb, Zr, Cr, V, Fe, W, Sn, Ta and Mn.Three samples, of Arkose, from the Kitwe Formation, Nchanga, Zambia (NOP741-16p, NOP741-17p 282 Appendix B and NOP741-19p) were analysed. Where possible, spots were chosen on the same rutile grains as laser ablation and away from any debris.
