Zircon UPb Discordance and its Relationship to

Zircon Upb Discordance And Its Relationship To

The pre-dissolution annealing effectively eliminates laboratory leaching effects, and permits recovery of the natural discordance signature. With this approach, the initial dissolution step samples zircon that is the most highly radiation damaged and the most discordant. The next steps are progressively lower in radiation damage and discordance.

Oct 12, 2004 In principle, this Pbloss may occur in four very different ways diffusion in metamict zircon, diffusion in pristine zircon, leaching from metamict zircon and recrystallization of metamict zircon. Here it is argued that, under conditions common in the continental crust, Pbloss is only possible in partially to strongly metamict zircons.

Even in unannealed zircon, in which leaching may induce unwanted isotopic fractionation, leachates are consistently more discordant than residues (Mattinson, 1994, 2011 Davis and Krogh, 2001). Clearly, fully understanding these phenomena is central to the reliability of chemically abraded zircon UPb ages.
