Dear Colleagues,
Erik Hauri, Elizabeth Ferriss, and Samer Naif are hosting a CIDER working group on electrical conductivity in olivine Monday and Tuesday, August 22-23 at the Carnegie Institution in Washington, DC. A primary focus will be on reconciling laboratory measurements of electrical conductivity in olivine as a function of the concentration of incorporated hydrogen as measured by FTIR and/or SIMS, with broader goals of understanding how best to interpret magnetotelluric (MT) measurements, the role of incorporated water vs. melt in the deep earth, and the usefulness of MT data going forward.
Confirmed participants include Shun Karato (Yale) and Takashi Yoshino (Okayama).
We also intend to discuss new SIMS measurements of the hydrogen content of olivine used for electrical conductivity measurements, including samples from the work of Karato, Yoshino, and Xiaozhi Yang (Nanjing), as well as H-D exchange samples from Wyatt Du Frane and Jim Tyburczy. If you have samples that should be included in these analyses, please contact us as soon as possible. Our intention is to publish this dataset in the EarthChem Library with all who contribute samples listed as co-authors and to make it publicly available in advance of the workshop.
Registration for the workshop is free, and a limited amount of travel support is available, particularly for US-based students and early-career scientists. To register or apply for travel support, please email ferriss@ldeo.columbia.ed
