摘要:

The “Five‐Mode Method” for evaluation of compiled data has been applied to three well‐established GIT‐IWG rock reference samples: Anorthosite AN‐G, Basalt BE‐N and Granite MA‐N. Results are compared to the accepted values, and where the two values are not in accord, a new procedure, the Graphical Moving Mode, is introduced. It is used to provide a clearer picture of the nature of the distribution of the raw data for each constituent, and, possibly to demonstrate the advantages of using the

摘要:

The preparation and homogeneity study of three certified reference materials, Plastic Clay GBW 03115, Potassium Feldspar GBW 03116 and Soda‐Lime Silica Glass GBW 03117 are briefly presented. The recommended values with their uncertainties were assigned, after a cooperative study with 18 laboratorie

摘要:

Publication patterns of CCRMP, NIST, and USGS reference materials are traced over the past 40 years by literature source, analytical method employed, and constituents measured. This is the first update to our 1987 paper which covered the period 1951 ‐ 198

摘要:

In 1990, the Institute of Geophysical and Geochemical Exploration prepared a series of certified reference materials of synthetic silicates and limestones. The silicate series (GSES I*) is composed of 11 samples with 28 ingredient elements and the limestone series (GSES II*) is composed of 9 samples with 29 ingredient elements. The standard series were prepared in ascending element concentration order of 1, 2 and 5. The synthetic standards were analyzed by a large number of laboratories with various reliable methods and then certified values were derived.

摘要:

Analytical data on 34 geochemically significant trace elements (Sc, V, Cr, Co, Ni, Cu, Zn, Ga, Rb, Sr, Y, Zr, Nb, Cs, Ba, Hf, Ta, Pb, The, U and REE) by using Inductively Coupled Plasma Mass Spectrometry (ICP‐MS), for 13 reference rock samples obtained from the Geological Survey of Finland are presented. For many elements, especially most of the heavy‐REE, concentrations are reported here for the first t

摘要:

The thermal neutron absorption cross‐section () of a sample is a measure of its ability to absorb neutrons and is a linear function of its total chemistry. is measured automatically by some downhole logging tools and is an important parameter for the lithological characterisation of formations. As part of a programme to accurately determine the of lithologies commonly encountered in the Ocean Drilling Program, it was necessary to evaluate the measurement of and this was, in part, achieved by measuring on a number of geochemical reference standards. Computed and measured values are reported here for thirteen geochemical reference standard
