Many of us in VGP utiliize a variety of instrumentation techniques to 
characterize volcanic glasses and minerals (as well as experimental run 
products). And with time, these techniques evolve and new ones develop 
-- all with their own "issues".  Session V19 is a place to discuss both 
both the advances and the challenges, so we particularly welcome 
unresolved challenges, so that the community can better address these.

V19: Microanalysis in Geoscience: Advances and Challenges

Microanalysis has been advancing, due to new instrumentation such as low
 kV field emission electron probes, new laser and sample chamber 
technology, EBSD and CL detectors, atom probe technology, 3-D 
tomography, new applications of laser ablation ICP-MS for insitu 
isotopic analyses and improved SIMS analysis of smaller volumes are just
 a few. The ability to push the analytical frontier to smaller volumes 
has allowed insight into new variations but not without analytical 
challenges, eg sample preparation, dealing with massive pixel/voxel 
data, the need for well characterized reference materials and 
interlaboratory reporting protocols. We particularly invite abstracts 
that document unresolved challenges in a broad range of applications.
