“…Since the extended uncertainty of analysis ) is a function of the analytical uncertainty on the values in the reference material in addition to crater aspect ratios and matrix, the advantages of using NIST SRM glasses outweigh the disadvantages of an unmatched matrix. The extended uncertainty on Mg is in fact twice as high (16%, Jochum et al (2012) their Table 1) for MACS3…”

“…However, these element fractionation effects are largest for siderophile elements, while lithophile elements like Mg are less or not at all affected (Czas et al, 2012;Fryer et al, 1995;Hathorne et al, 2007;Jochum et al, 2012). Elemental fractionation is higher for smaller craters than for larger craters at constant sampling time.…”

“…Strnad et al [145] and Chen et al [47] reported that the analysis results of carbonate samples calibrated against silicate reference glasses and those of carbonate samples calibrated against reference carbonate pellets exhibited no significant difference. However, Jochum et al [95] suggested that accurate results can be obtained through calibration against silicate reference glasses for large ion lithophile elements but that matrix-matched standard calibration may be required for chalcophile and siderophile elements.…”

“…The classification of elements based on the FI roughly follows the Goldschmidt geochemical classification of elements [86,97,102]. Košler et al [95] found that the formation of phases of different mineralogy and/or chemical composition from the original sample at the ablation site can result in elemental fractionation (non-stoichiometric sampling) in material delivered to an ICP-MS for quantitative analysis. For example, both larger spherical particles and agglomerates of smaller particles produced by the ablation of zircon (ZrSiO 4 ) are mixtures of amorphous and crystalline materials-most likely zircon, baddeleyite (ZrO 2 ) and SiO 2 .…”

Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS), which is a rapidly developing analytical technique for the analyses of trace elements and isotopes, plays an important role in advancing the study of Earth science, especially with respect to micro-geochemistry. This article reviews the application of LA-ICP-MS in the elemental analysis of solid geological samples. Although LA-ICP-MS has been widely used in the spatial resolution analysis of element compositions and rapid bulk analysis of whole-rock and soil samples, the analysis accuracy is restricted by numerous factors, including the instrumental conditions, the elemental fractionation and matrix effects, the lack of sufficient matrix-matched reference materials, and the strategies for quantitative calibration and sensitivity drift correction. According to the type of samples and the analyte elements, the analysis accuracy can be improved through the optimization of instrument conditions and the adoption of suitable correction strategies and reference materials.

Lower Paleozoic sedimentary rocks in the northwestern Tarim basin were strongly altered by complicated geofluids, which resulted in the occurrence of various diagenetic minerals (e.g., dolomite). Here, in situ major, trace, and rare earth element geochemistry of Lower Ordovician diagenetic dolomite grains as well as petrography were performed to unravel the geochemical features, the nature, and origin of the diagenetic fluids. The results indicate that different geochemical information can be detected within a single sample, even within a single dolomite grain. Five generations of diagenetic dolomite have been identified based on geochemical signatures, resulting from four distinct types of diagenetic fluids: (1) HREE enrichment (PAAS-normalized), low RREE, no Eu anomaly, low Mn, Ba, moderate Fe, and high Sr contents are probably due to early burial dolomitizing fluids; (2) MREE enrichment, high RREE, high Mn, Fe, and low Sr content are likely to be associated with Devonian deep-circulating crustal hydrothermal fluids; (3) flat or LREE enrichment pattern with obviously positive Eu anomaly is inferred to be linked to Permian magmatic hydrothermal fluids; and (4) flat REE pattern, moderate RREE, no Eu anomaly, low Mn, Ba, moderate Fe, and high Sr contents are probably due to late burial dolomitizing fluids. The significances of in situ method demonstrated in this study, compared with the whole rock analysis, include not only contamination-free analysis but also unraveling the internal geochemical variation within a single sample or a mineral grain. Thus, for the geochemical study of complicated diagenetic process, in situ method should be preferentially considered.
