The 10th Annual Carnegie AGU reception was a great success!  Carnegie Science friends, alumni, postdocs and staff gathered in San Francisco to catch-up and chat about future collaborations, job opportunities and more. This long standing reception tradition brings together past and present members of the Carnegie family and is always an event to look forward to.

Posters

Stanislav Sinogeikin, associate director of HPCAT, presented his poster "Fast Compression and Decompression capabilities at HPCAT, APS" during the Advanced Experimental, Computational, and Analytical Techniques for Mineralogy and Mineral Physics morning poster session.  His poster explains how recent advances in synchrotron sources, x-ray optics, fast area detectors, and sample environment control have enabled many time-resolved experimental techniques for studying materials at extreme pressure and temperature conditions.

Talks

Yoshio Kono presented his research about ultrahigh-pressure structure of GeO2 glass with coordination number >6: implications for structure of magma at the core-mantle boundary during his invited talk on Tuesday morning.  Kono's talk explained how new experimental evidence of ultrahigh pressure structural transition in GeO2 glass with Ge-O coordination number (CN) significantly greater than 6 is investigated using a newly developed double-stage large volume cell combined with multi-angle energy dispersive X-ray diffraction technique for in situ amorphous structure measurement during the Physics and Chemistry of the Deep Earth session.

Staff Scientist Alex Goncharov discussed radiative conductivity and abundance of post-perovskite in D’’ during his talk on Tuesday.  Goncharov explained how he constrained the radiative component of the thermal conductivity in post-perovskite at core-mantle boundary conditions by using optical spectroscopy in a laser-heated diamond anvil cell using a pulsed supercontinuum probe.

Postdoctoral Associate Renbiao Tao wrapped up our Tuesday at the AGU 2016 Fall Meeting with his talk on experimental investigation of Fe3+- rich majoritic garnet and improvement of the majorite geobarometer. Tao's team used a combination of “Flank method” and charge balance calculations to confirm that the majoritic garnet is an important Fe3+ sink in the deep upper mantle.

Talks

Asmaa Boujibar, a Carnegie fellow, presented her invited talk about U, Th, and K in planetary cores: Implications for volatile elements and heat production during Wednesday's AGU Fall Meeting.  She confirms that U, Th, and K become more siderophile with decreasing fO2 and increasing sulfur content, with a stronger effect for U and Th in comparison to K. Hence Mercury’s core is likely to have incorporated more U and Th than K, resulting in the elevated K/U and K/Th ratios measured on the surface.

Posters

Mike Ackerson, Carnegie fellow at GL, presented his poster, "Experimental observations of aTiO2 in rutile-undersaturated silicate melts and implications for estimating aTiO2 in natural systems" during Wednesday's New Insights on Igneous and Metamorphic Processes from Nontraditional Thermobarometers and Geospeedometers poster session. 

Postdoctoral Associate Megan Duncan explained her poster, "The Effect of Carbon on the Dihedral Angle of Metallic Melt with Implications for the Timing and Efficiency of Core Formation" during Wednesday's The Physical Properties of Core Materials poster session.

Talks

Carnegie Fellow Zhixue Du presents his results about whether early geodynamo is powered by magnesium exsolution at this morning's The Earth's Core: Constraints on the Earth’s Metallic Heart from Multidisciplinary Approaches session. 

Bob Hazen presented "The Private Lives of Minerals: Social Network Analysis Applied to Mineralogy and Petrology" to a captivated audience during Thursday's BIG Value of Small Data: Realizing the Huge Potential of the Diverse "Long Tail" Communities to Contribute to the Advancement of Science session.



Posters

Chao Liu presented his poster, "Reconstructing the evolution of first-row transition metal minerals by GeoDeepDive" to AGU attendees at this morning's BIG Value of Small Data: Realizing the Huge Potential of the Diverse "Long Tail" Communities to Contribute to the Advancement of Science poster session.

Carnegie alums Neil Bennett and Colin Jackson present posters "Pressure, Sulphur and Metal-Silicate Partitioning: Does the Formation of Metal-Sulphur Species in Silicate Melt Affect the Parameterisation of Experimental Results?" and "Discrete stages of core formation survive the Moon-forming impact" respectively at this morning's poster session.
