Tephrological implications of beam size—sample‐size effects in electron microprobe analysis of glass shards

Abstract: Hunt, J. B. and Hill, P. G. 2001. Tephrological implications of beam size-sample-size effects in electron microprobe analysis of glass shards.ABSTRACT: This paper concerns the potential consequences of varying procedures for the determination of tephra geochemistry by electron microprobe. Application of electron probe microanalysis to tephrostratigraphical methods has increasingly facilitated the resolution and refinement of Quaternary chronology associated with records of proxy-environmental or proxyclimatic … Show more

“…The electron probe had an operating current of 15 nA, voltage of 20 kV and a 10 s peak count time per pair of major elements. Total exposure time was 50 s with blanking of the beam during spectrometer repositioning to prevent damage (Hunt and Hill, 2001). Sodium was measured at the start and end of each analysis to monitor loss through mobilization (Hunt and Hill, 1993).…”

“…Indeed, minimization of Na loss is one of the greatest challenges of glass analysis, and several EMP methods and correction schemes to ''properly'' estimate Na 2 O content have been proposed and used in the past (e.g. Nielsen and Sigurdsson 1981;Devine et al 1995;Hunt and Hill 2001;Morgan and London 2005). It is worth noting that some glass analyses employed in calibrating the chemometric equations (see references in Table 1 and Rutherford and Devine 1996;Chertkoff and Gardner 2004;De Hoog et al 2004; Piscaglia 2011) did not utilize any of these EMP methods.…”

“…Accuracy was monitored by reference material measurements on Lipari obsidian (major elements, e.g. Hunt and Hill, 2001), ALV (sulphur) and Ke13 (chlorine) glass. 30 individual point measurements were bracketed by two reference material measurements at the beginning and the end of each analytical series.…”
