An assessment of nuclear microprobe analyses of B in silicate minerals
(2003) In American Mineralogist 88(10). p.1601-1604- Abstract
- With recent findings of substantial amounts of B in rock-forming minerals, it has become evident a need exists for microprobe techniques allowing quantitative B determinations in minerals. A microprobe method based on the nuclear reaction B-11(p,alpha)2alpha has the potential to become a powerful tool for analyses of minerals with B contents spanning a wide concentration range. In this paper, we present nuclear microprobe analyses of B in a set of silicate minerals containing stoichiometric concentrations of B in the range 1.9-8.8 wt%. Our results strongly indicate that nuclear reaction analyses of silicates utilizing the B-11(p,alpha)2alpha nuclear reaction are virtually matrix-insensitive, and saturation effects are negligible within the...

Our results strongly indicate that nuclear reaction analyses of silicates utilizing the B-11(p,alpha)2alpha nuclear reaction are virtually matrix-insensitive, and saturation effects are negligible within the studied range of B concentrations. This finding suggests that it is adequate to use a single B standard for calibration purposes for analyses covering wide ranges of B concentrations in silicates. In addition, we demonstrate how B-concentration maps of high contrast and resolution may be produced by scanning the proton beam over the samples. (Less)
