Goldschmidt 2007 Virtual Special Issue

This Virtual Special Issue contains six papers published in GGR that were originally read at the Goldschmidt Conference in Cologne 2007.

Three papers form a valuable collection on the U-Pb isotopic dating of zircon, covering ion microprobe and laser ablation ICP-MS techniques as well as highlighting new and established zircon reference materials. Other contributions cover analytical techniques for elemental sulphur, sampling and analysis of atmospheric particles and a review of time-of-flight SIMS for organic geochemistry.
