JR-3, a LIL-enriched GSJ rock reference sample

ABSTRACT

Nineteen elements were measured for a new GSJ rock reference sample, JR-3, by instrumental neutron activation analysis. It is found that JR-3 is much more abundant in large ion lithophiles such as rubidium, the rare earth elements, hafnium, tantalum, thorium and uranium than any other GSJ rock reference materials. No significant heterogeneity of the sample powder is detected for the amount of 60 mg level. Thus, JR-3 is especially useful as an analytical standard for those elements.
