Abstract

An updata REE measurement of gabbro GOG-1 was carried out by means of neutron activation analysis (NAA). The availability of high amounts of rock powder allowed the sample to be well ground and homogenized before analysis. Homogeneity tests, carried out on different aliquots, show that GOG-1 samples can be considered homogeneous when over 50 mg aliquots of rock powder are employed for analytical work. Results from ICP-AES and SIMS investigations of REE in gabbro GOG-1 are in quite good agreement with NAA data and support the possibility of employing GOG-1 rock samples as reference material for geoanalysis.
