摘要:

The advantages of neutron activation analysis as applied to geological material are discussed. Analytical work performed in the authors’ laboratories is described, and preferred values from this work for 38 elements in some USGS standard rocks are presented and compared with literature dat

摘要:

Fifteen geochemical reference samples have been analysed for palladium using the stable isotope dilution technique. These include seven USGS, five CRPG and three CCRMP samples. Our results ape in reasonable agreement with the presently accepted values for the USGS samples, but are significantly lower than the present CCRMP values. Our data for the CRPG samples are the first to be published. This is the first reported study of the determination of palladium in silicate samples using the isctope dilution technique.

摘要:

The state of the art for silver determination in silicate rocks is discussed on the basis of available data on geostandards. A neutron activation procedure for silver in rocks is briefly described, and data on seven new USGS standard rocks are presented and discussed.

摘要:

The chemical composition of eight german ore standards, seven iron ores and one manganese ore, is presented. A certificate of analysis supplied with each sample is given as an example; it contains the names of the co‐operating laboratories, the‐ mean value obtained by each laboratory for each element and a statistical evaluation of the laboratory means. A summary is also given of the methods u
