“…The rest of the trace elements were analyzed using Agilent 7500ce plasma-mass spectrometer (ICP-MS) coupled with a New Wave UP-213 laser ablation system at the University of Mainz. Rock powders were melted to form glass beads without any fluxing agent on an iridium strip heater in an argon atmosphere and analyzed by laser sampling of the glasses (Nehring et al, 2008). The melting takes place in a closed box under an argon atmosphere.…”

“…Based on the sample preparation technique, LA-ICP-MS methods have been applied to the bulk analysis of various samples, including (1) the direct analysis of a rock slice [24,126], (2) the analysis of pressed-powder pellets both with binders [1, 26,127] and without binders [128], and (3) the analysis of fused glasses fused both with a flux agent [6, 129,130] and without a flux agent [22,23,25,61,[131][132][133][134].…”

“…B, Li and REE) [137]. A flux-free fusion technique involves the direct melting of the rock powders in an Ar environment into homogeneous glasses at 1300-1800°C using an iridium strip heater [22,25,133,134], a tungsten strip heater (Hf and Ta pollution may exist) [132] or a molybdenum strip heater [23,138], which avoids the above problems caused by the flux agent. For high-SiO 2 rocks, high-purity MgO needs to be added to reduce the melt viscosity and result in homogeneous glasses [134].…”

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.

“…Rare-earth elements (REE), Hf, Ta, Th and U of selected samples were analysed on fused discs by LA-ICP-MS using an Agilent 7500ce equipped with a Merchantek NewWave 213 nm Nd-YAG laser at the University of Mainz, following procedures described in Nehring et al (2008). For U-Pb geochronology zircons were separated from the bulk samples using standard techniques [hydraulic press, rotary mill, Wilfley table, Frantz isodynamic magnetic separator and heavy liquids (methylene iodide)].…”

The Pirgadikia Terrane in northern Greece forms tectonic inliers within the Vardar suture zone bordering the Serbo-Macedonian Massif to the southwest. It comprises Cadomian basement rocks of volcanic-arc origin and very mature quartz-rich metasedimentary rocks. U-Pb laser ablation sector-field inductively-coupled plasma mass spectrometry analyses of detrital zircons from the latter reveal a marked input from a Cadomian-Pan-African source with minor contribution from Mesoproterozoic, Palaeoproterozoic and Archaean sources. The metasedimentary rocks are correlated with Ordovician overlap sequences at the northern margin of Gondwana on the basis of their maturity and zircon age spectra. The Pirgadikia Terrane can be best interpreted as a peri-Gondwana terrane of Avalonian origin, which was situated close to the Cadomian terranes in the Late Neoproterozoic-Early Palaeozoic, very much like the Istanbul Terrane. The second unit investigated is the Vertiskos Terrane, which constitutes the major part of the Serbo-Macedonian Massif in Greece. It comprises predominantly igneous rocks of Silurian age and minor metasedimentary rocks of unknown age and provenance. U-Pb analyses of detrital zircons from a garnetiferous mica schist of the Vertiskos Terrane indicate derivation from 550 to 1,150 Ma-old source rocks with a major Cadomian peak. This, combined with minor input of [1,950 Ma-old zircons and the absence of ages between ca. 1.2 and 1.7 Ga suggests a NW Africa source. The protolith age of the garnetiferous mica schist is presumably Early Ordovician. One sample of garnet-bearing biotite gneiss, interpreted as meta-igneous rock, comprises predominantly subhedral zircons of igneous origin with late Middle Ordovician to Silurian ages. We suggest that the rock association of the Vertiskos Terrane is part of an ancient active-margin succession of the Hun superterrane, comparable to successions of the Austro-and Intra-Alpine Terranes. The new data of this study provide evidence of occurrences of Avalonia-and Armorica-derived terranes in the Eastern Mediterranean and moreover help to clarify palaeogeographic reconstructions for the peri-Gondwana realm in the Early Palaeozoic.
