The April issue of American Mineralogist is out.
Check out the following paper by Yu Ye, David A. Brown, Joseph R. Smyth, Wendy R. Panero, Steven D. Jacobsen, Yun-Yuan Chang, Joshua P. Townsend, Sylvia-Monique Thomas, Erik H. Hauri, Przemyslaw Dera and Daniel J. Frost: Compressibility and thermal expansion of hydrous ringwoodite with 2.5(3) wt% H .
‘Optical reflectivity of solid and liquid methane: Application to spectroscopy of Titan’s hydrocarbon lakes’ has been published in GRL. The link will lead you to the paper.
Creating some support pages for COMPRES Graduate Distance Education Course 2012, which starts next Tuesday, 11 am PST.
If anybody could check if they can use the Forum, I’d appreciate it.
COMPRES Graduate Course 2012 – Information – Links to Forum and List of Attendees
Let’s try to assemble all the links we’ve lost on FB. Let’s start with the links for experiment SiO2_21. Your comments about experiments and links to Excel-files will be archived under category ‘NeRD Lab Discussions’.
The UNLV Geoscience department will host its annual Geosymposium this Friday and Saturday. Saturday will also be the day of the Festival of Communities 2011 here on the UNLV Campus, which amongst other things gives UNLV undergraduates the chance to present their research. Here you can find a poster undergrad May Sas has put together for both events: Sas et al. 2011.
Two new articles entitled “Optical absorption, luminescence, and electron paramagnetic resonance (EPR) spectroscopy of crystalline to metamict zircon: Evidence for formation of uranyl, manganese, and other optically active centers” and “Location and quantification of hydroxyl in wadsleyite: New insights” have been published in the February-March issue of American Mineralogist.

A new conference abstracts is online, which has been submitted for presentation at the EGU General Assembly (Website EGU 2010) in Vienna from 2nd – 7th May. Session information is given below.
Session: GMPV26/GD1.9 – New insights into the Deep Earth Part II: Hydration and dehydration of the Earth’s crust and mantle – mechanisms and consequences (co-sponsored by EMU)
Conveners:
Monika Koch-Müller (Deutsches GeoForschungsZentrum – GFZ Potsdam, Germany)
Jannick Ingrin (LMTG, Université de Toulouse, France)
Sylvia-Monique Thomas (Northwestern University, USA)
The presence of water in solids of the Earth’s crust and mantle has enormous effects on the dynamics of processes in the Earth. Hydrogen may be stored in hydrous minerals such as amphibole, serpentine and talc as well as in nominally anhydrous minerals (NAMs). The hydrogen incorporated in these minerals may change their stability fields and physical properties such as electrical conductivity, chemical diffusion, rheological behavior (hydrolytic weakening), transformation kinetics and phase transitions but also their elasticity. The release of water through dehydration processes may enhance melt generation and trigger earthquakes. The formation of dense hydrous magnesium silicates (DHMS) may be an effective way to recycle water deep into the Earth’s mantle. The aim of this special session is to bring together scientists from several disciplines to discuss some of the following topics: hydrogen solubility in minerals as a function of P, T and paragenesis; hydrogen and deuterium analysis in deep crust and mantle minerals from rocks with different geodynamic histories; effect of hydrogen on properties of NAMs; hydrogen mobility in minerals; high-pressure stability and behavior of hydrous minerals.
Solicited speakers: Anne Peslier, Nathalie Bolfan-Casanova
