Hi,
Can someone point me to a summary of cation-oxygen bond distances in common
minerals (e.g., garnet) and their PT dependencies? I'm thinking of
something like Hazen and Finger (1979; JGR; Bulk modulus-volume
relationship for cation-anion polyhedra), but including expansivities, and
with more minerals and elements.
Is there even a summary, or does it take finding a bunch of specific
studies?
Forgive me if this is obvious to the crystallographers. I'm not in a
location that allows effective literature searches.
Thanks,
Matt
Dear Matt,
A useful set of summaries up to the year 2000 is in RiMG volume 41:
Hazen, R.M. and Downs, R.T. [Editors] (2000) High-Temperature and
High-Pressure Crystal Chemistry. Washington: Mineralogical Society of
America, Reviews in Mineralogy and Geochemistry, Volume 41, viii, 596 p.

Dear colleagues,
I am looking for advice on simultaneous use of a single ICP-MS for
laser-ablation and conventional solution analyses.
We have recently acquired a LA-ICP-MS (ESI NWR 193 coupled with Agilent
7900) with primary objective to analyze trace element compositions in
silicate and oxide minerals. For various collaborative reasons, we are
considering running conventional solution analyses (with common trace
elements) on the same ICP-MS unit as well.
I am wondering about experience (contras, contamination, substantial
dilution, cone exchange etc.) from those who do or do not use and switch
both approaches routinely.
With many thanks,
David
