Rationale In situ trace element analysis of melt inclusions by laser ablation inductively coupled plasma mass spectrometry (LA‐ICP‐MS) provides important geochemistry information. However, the precision and accuracy this technique are affected many factors, such as matrix effect, conditions, calibration method. addition, previous LA‐ICP‐MS studies ablated entire along with their host minerals obtained composition deconvoluting mixed signal, which may induce much uncertainty. Methods A 193 nm...
Abstract The North China Craton (NCC) is believed to be the best example of cratonic destruction. However, processes leading destruction remain unclear, largely due a lack knowledge nature Mesozoic NCC lithospheric mantle. Here we report new petrological and geochemical data for Early Cretaceous basalts, which provide insights into underlying basalts (all tholeiites) show limited variation in composition. In contrast, olivine‐hosted melt inclusions from these display wide range compositional...
This contribution presents new U-Pb geochronological data and attempts to elucidate the complex evolution history of various garnet types identified from two kimberlite pipes in Wafangdian diamond mining district, southern Liaoning Province. These calcic garnets are dominated by andradite with relatively low proportions schorlomite, grossular pyrope. Abundant euhedral subhedral, highly brecciated phenocrysts hosted LN30 "carbonatite-like" samples yield a lower-intercept age 459.3 ± 3.4 Ma,...
In situ Pb isotope analyses of tiny melt inclusions using laser ablation-multi-collector-inductively coupled plasma-mass spectrometry (LA-MC-ICP-MS) are crucial for exploring the origins mafic lavas. However, quantitative use this technique with low-Pb (<10 ppm) is difficult due to their low 204 content and Hg interference.Pb isotopic ratios various reference glasses olivine-hosted were determined LA-MC-ICP-MS. Multiple ion counters used simultaneously determine signal intensities all...
Abstract Melt inclusions provide unique insights into magmatic sources and processes. This study presents a method for simultaneously measuring Pb isotopes trace elements in melt using 193 nm excimer laser ablation system coupled to multiple‐collector inductively plasma‐mass spectrometer (MC‐ICP‐MS) sector‐field ICP‐MS (SF‐ICP‐MS). The ablated aerosol was split with Y‐shaped connector two gas streams, which were transported mass spectrometers. Lead measured on the MC‐ICP‐MS, while element...
In this study, we developed a method for measuring Sm–Nd isotopic ratios in samples with low Nd contents (<100 μg g −1 ) by LA-MC-ICP-MS.
