Three new rock reference samples, Rhyolite JR-3, Gabbro JGb-2 and Hornblendite JH-1 have been prepared by the Geological Survey of Japan for collaborative studies on their chemical composition. Twenty-eight major, minor and trace elements were determined and presented. The results of homogeneity tests showed that all elements are considered to be distributed homogeneously in each reference sample. Geological and mineralogical characteristics are also described. 相似文献

ICP-MS ANALYSIS OF BASALT BIR-1 FOR TRACE ELEMENTS 总被引：6，自引：0，他引：6
The concentrations of 27 trace elements in the basalt BIR-1, as well as in other mafic rock reference materials, have been determined by ICP-MS, using pure elemental solutions for external calibration and standard additions. Concentrations of rare earth elements in BIR-1 for the new ICP-MS data, agree with compiled values, and previous ID-SSMS results, whereas ICP-MS data on HFSE's are systematically higher by about 40% to 70% than ID-SSMS, but are consistent with data generated at other ICP-MS laboratories. 相似文献

During the five-year period (April 1981 - March 1986), a series of fifteen rock reference samples, "Igneous rock series", has been prepared by the Geological Survey of Japan (GSJ). Based on the data available (published and communicated), consensus values for major, minor and trace elements have been derived; these values are presented for this second series of samples as well as for the first series of two samples, Granodiorite JG-1 and Basalt JB-1. 相似文献

The six ANRT rock reference samples (DR-N, UB-N, BX-N, DT-N, GS-N, FK-N) have been distributed as reference samples for nearly twenty years. All available data on trace elements in these samples are presented and evaluated. It has been possible to assign working values for nearly 40 trace elements. These samples prepared in 600 to 1300 kg quantities are expected to last for some decades to come. 相似文献

The USGS reference glasses GSA-1G, GSC-1G, GSD-1G, GSE-1G, BCR-2G, BHVO-2G and BIR-1G were investigated by different analytical techniques. All these materials have a geological (basaltic) matrix and are therefore useful in igneous geochemistry as matrix-matched reference materials for microanalytical techniques. The new GS glasses have trace elements in groups at concentration levels of about < 0.01, 5, 50 and 500 μg g-1 . Their major element compositions have been determined by EPMA, and trace elements have been analysed by LA-ICP-MS and two isotope dilution techniques using TIMS and ICP-MS. EPMA and LA-ICP-MS analyses indicated that the USGS reference glasses are homogeneous at the μm to mm scale with respect to major (variations < 1-2%) and most trace elements (variations 1-4%). Trace element data obtained from the different analytical techniques agreed within an uncertainty of 1-5%, indicating that between method results are comparable. Therefore, the preliminary working values for the four USGS GS glasses calculated from these data have a low level of uncertainty. 相似文献

Results are presented for 26 to 30 trace elements determined in four rock reference materials of geochemical interest: USGS Basalt BHVO-1, Rhyolite Obsidian NIST 278, Basalt NIST688, and Phosphate Rock NIST694. Determinations were made by inductively coupled plasma mass spectrometry (ICP-MS). Good agreement was obtained among solution standard comparison and standard addition analytical techniques, and among samples prepared with different dissolution methods. Generally good agreement was obtained between determined trace element values and values reported in the literature. 相似文献

Rare earth elements were determined by secondary ion mass spectrometry for 13 silicate rock samples, ranging from ultramafic-mafic to acidic compositions, 2 feldspar and 1 biotite separates. As a whole, the investigated samples are characterized by matrices and rare earth elements spectra covering most geological applications. The present data are compared with reference values. The advantage of using secondary ion mass spectrometry as a fundamental tool for trace element detection in bulk samples in the few ppm-ppb region is demonstrated. 相似文献

Nine new rock reference samples of the "Sedimentary rock series", Chert JCh-1, Dolomite JDo-1, Lake sediment JLk-1, Limestone JLs-1, Stream sediments JSd-1 to JSd-3, and Slates JS1-1 and JSl-2 have been prepared by the Geological Survey of Japan(GSJ). Thirty major, minor and trace elements were determined using atomic absorption spectrometry, flame emission spectrometry, infrared absorption spectrometry and wet chemical techniques. The results of homogeneity tests showed that almost all elements, with a few exceptions, are considered to be distributed homogeneously in each reference sample. 相似文献

Silver content of silicate rook samples rarely exceeds 200 ppb. For determining such low levels of silver, a solid sampling flame atomic absorption method has been developed and has been applied to the analysis of several silicate rock reference samples. These results are compared with the sparse published data. Using silver as an example, the usefulness of solid sampling procedures for testing the repartition of volatile trace elements during the processing of new rock reference samples is illustrated. 相似文献

The collection and preparation of two soil reference samples and two till reference samples are described. Like their predecessors the LKSD series and the STSD series, the TILL series are characterized for total elements and for elements derived by partial extractions. Provisional data are presented for major, minor and trace elements. In addition, information data from a single source are provided for a number of elements derived by EPA digestions 3050 and 3051; these data allow a comparison with other partial extractions reported herein. 相似文献

The concentrations of 25 trace elements have been determined in 15 international standard rock samples by isotope-dilution spark source mass spectrometry (ID-SSMS). This technique yields reliable data down to the ppb concentration range. The agreement between most of our data and recommended values is within 10%. However, for reference samples with low trace element contents (BIR-1, NIM-N, PCC-1, DTS-1), differences between our data and the literature can be as large as a factor of 80. 相似文献

The influence of non‐spectral matrix effects on the determination of twenty‐two trace elements (Rb, Sr, Y, Cs, Ba, lanthanides, Pb, Th and U) in rock samples using ICP‐MS was investigated. Three types of multi‐element solutions were synthesised containing the twenty‐two trace elements, In, Tl and ten major rock‐forming elements with varying mass fractions mimicking the compositions of basalt, peridotite and dolomite. The synthetic solutions were conditioned to have dilution factors (DF) of 1000–10000. The extent of sensitivity suppression relative to the DF = 10000 solution became more significant for smaller DF solutions, which was not constant across different elements in a single solution but displayed general dependence on m/z. This indicates that at least two internal standards (e.g., In and Tl) are required for the correction of sensitivity variation. On the basis of the results, a new isotope dilution‐internal standardisation method for the determination of twenty‐two trace elements with ICP‐MS was developed, in which the sensitivity variation was corrected by monitoring two enriched isotopes, 113In and 203Tl. This method, coupled with the quantitative correction of interference from oxides and hydroxides, achieved precise determination of twenty‐two trace elements in some rock reference materials with reproducibilities of ±2% for basaltic to andesitic samples. 相似文献

XRF AND INAA DETERMINATIONS OF MAJOR AND TRACE ELEMENTS IN GEOLOGICAL SURVEY OF JAPAN IGNEOUS AND SEDIMENTARY ROCK STANDARDS 总被引：1，自引：0，他引：1
Major and trace element analyses have been obtained by wavelength dispersive X-ray fluorescence for the Geological Survey of Japan Igneous rock series and selected samples from the Sedimentary rock series reference samples. Additional trace element data for the Igneous rock series were obtained by instrumental neutron activation analysis. Samples were analyzed multiple times for 10 major elements (with loss-on-ignition) and the following trace elements; As, Ba, Ce, Co, Cr, Cs, Cu, Eu, Ga, Hf, La, Lu, Nb, Nd, Ni, Pb, Rb, Sb, Sc, Sm, Sr, Ta, Tb, Th, U, V, W, Y, Yb, Zn and Zr. 相似文献

The 18 Chinese geochemical standard reference samples GSD 9-12 (stream sediments), GSS 1-8 (soils) and GSR 1-6 (rocks) were prepared after GSD 1-8 (stream sediments) for even wider and increasing needs of geology, exploration geochemistry and geochemical analysis. Usable values of 41 trace, minor and major elements of the 18 samples were published in 1984. In the following two years, efforts were concentrated on the determination of other elements, most of which are more difficult to determine accurately and hence not many data were available in the literature. At the same time, additional data on the 41 elements already evaluated were also submitted. In all, 155 234 results were available along with the 35 284 analytical data submitted. The processing of samples, the examination of sample homogeneity, the plan of collaborative analysis of the samples, and the criteria for defining the recommended values are described. The recommended or reference values of the 72 constituents, to-gether with the 35 284 analytical data of the 18 samples are published in this paper. 相似文献
