Front cover: Zircon was a major focus of research at GEMOC in 1999; the trace element and isotopic zoning of this resistant mineral record its magmatic and metamorphic history. The holes in the zircon are ablation pits from LAM-ICPMS analyses, which yielded U-Pb ages and the trace element compositions of different zones. LAM-MC-ICPMS analyses gave high-precision spot analyses of Hafnium isotope composition (inset), which showed that many granitoid rocks retain isotopic evidence of mixing between several components. The arrow shows the direction of isotopic zoning recorded in core-to-rim analyses of individual zircon grains in a quartz diorite from the Pingtandao complex, SE China. The technique is now being applied to zircon populations from sediments, for analysis of crustal genesis over large continental areas. See Research Highlights
