“…15, 2013;Jochum et al, 2005aJochum et al, , 2006 except for GSD-1G, which was doped with selected rare earth elements and transition metals including Pb (48 ppm, Guillong et al, 2005). These reference glasses have been well characterized for Pb isotopes (Elburg et al, 2005;Jochum et al, 2005bJochum et al, , 2011Paul et al, 2005) and therefore, were suitable for validating the analytical method. The selected USGS glasses were all basaltic in composition, whereas the MPI-DING glasses covered a wide range of compositions: basalt (KL2-G), andesite (StHs6/80-G), rhyolite (ATHO-G), quartz-diorite (T1-G), and komatiite (GOR132-G).…”

“…Note that a large instrumental mass bias (e.g., Hirata, 1996;Kent, 2008a;Kimura et al, 2013) in the Pb isotopes region was corrected for by the standard bracketing method (Elburg et al, 2005;Paul et al, 2005;Kent, 2008a;Kimura et al, 2013). The remaining interlinearity issue of the MICs can be well compensated in the 10-300 kcps range with the standard bracketing method.…”

“…In situ analysis of Pb isotopes by laser ablation coupled with multiple-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) has been applied to a wide variety of geological samples, including silicate minerals, glasses and melt inclusions (Mathez and Waight, 2003;Peate et al, 2003;Gagnevin et al, 2005;Kent and Dilles, 2005;Paul et al, 2005;Simon et al, 2007;Kent, 2008a, b;Paul et al, 2011;Westgate et al, 2011;Kimura et al, 2013). For Pb-rich material and/or when a large ablation spot is possible, LA-MC-ICP-MS using Faraday collectors can provide in situ Pb isotope analysis with accuracy of several per mil, even for the minor 204 Pb (cf., Kimura et al, 2013).…”

“…Because of these advantages, this technology has quickly been adopted for in situ Pb-isotope analysis. For example, Paul et al 10 using a 93 mm laser spot analyzed the Pb isotopic composition of glass standards. Kent 11 made a comparison between the Faraday cup and ion counting systems for Pb-isotope analysis and argued that the precision is strongly dependent on ion intensities.…”

Pb isotope compositions of melt inclusions provide unique information about the composition of primary magmas and their source. In this study, we have developed a method for measuring Pb isotopes in small olivine-hosted melt inclusions (>40 mm) from young and old volcanoes by LA-MC-ICP-MS. We used a new interface cone assemblage consisting of a Jet sample cone and X skimmer cone. A small flow of N 2 gas was added to the carrier gas and passed through the assemblage to enhance the signal intensity. In addition the energy and repetition rate of the laser conditions were reduced and the signal integration time was shortened in order to lengthen the laser ablation time and to collect enough data. Mass bias and instrument drift were corrected using a standard-sample-standard bracketing method. The analysis routine employed eight ion counters to receive 238 basalts, but also from old samples that require correction for U-Th decay.

“…Isotopic fractionation corrections were performed using the Exponential Law and NIST SRM610 values from Baker et al (2004) by means of standard-sample bracketing (e.g., Jochum et al 2006;Kent 2008;Paul et al 2005;Simon et al 2007). The fractionation factor was determined using the 208 Pb/ 206 Pb ratio measured in NIST SRM 610.…”

Panamá Viejo, founded in 1519 by the Spanish explorer Pedrarias Dávila, was the first permanent European settlement on the Pacific Ocean, and became a city, by royal decree, in 1521. Shortly after its creation, the city became an important base for trade with Spain. In 1671, the English pirate Henry Morgan waged an attack on Panamá Viejo, which resulted in a fire that destroyed the entire city. A new settlement built a few miles west, called Casco Antiguo or San Felipe, is now the historic district of modern Panama City. The Pb isotopic compositions of the glazes on the surface of sixteenth to seventeenth century majolica pottery sherds from Panama Viejo and Casco Antiguo (both in Panama), and Lima (Peru) were determined via non-destructive laser ablation multi-collector ICP-MS (LA-MC-ICP-MS). The contrast in Pb isotopic compositions in the glazes on ceramics recovered in different locations demonstrate that early majolica pottery production during this period used Pb obtained from the Andes. However, the Pb used in later majolica production in Panama is of Spanish origin. After Panamá Viejo was burned to the ground, Panamanian majolica production ended.
