Tourmaline Standard/Reference Material

[DavidAdams]

Does anyone know of/have access to a good, well characterised tourmaline standard reference material?

Thanks!
Dave

Hi Dave,

a set of tourmalines (dravite, elbaite, schorl) from the Harvard collection was characterized by Dyar et al. (2001) and Leeman et al. (2001).

It is available for sale from the International Association of Geoanalysts: (http://iageo.com/microanalytical-reference-materials/) either individually or as a set.

Here is a just published (Oct 2020) paper on the "reference Tourmalines" for which previously published EPMA major and minor reference values are somewhat called into question.
