“…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).…”
