Stratigraphic Correlation in the Afar Depression, Ethiopia

Prof. Beverly Saylor and Josh Angelini traveled to Ethiopia to determine stratigraphic relationships between sites bearing fossils of human ancestors.

Prof. Saylor and Josh measured stratigraphic sections, inspected aerial photos and satellite imagery, mapped formations using differential GPS, and took samples for geochemical analysis in the ongoing effort to sort out the complex stratigraphy of the study area. Dr. Mulugeta Alene, a structural geologist at Addis Ababa University joined them in the field to help in the identification of faults and other structural features of this region, which has a complex tectonic and volcanic history. During this field season, the geologists focused on correlating several sites by means of volcanic tuffs, which are important not only for correlation but for radiometric dating as well. Many samples were taken, the analysis of which will provide evidence toward the confirmation or rejection of correlative hypotheses posited in the field.

Post-Doctoral Position Available

Post-Doctoral Position in Experimental Petrology and Geochemistry

A post-doctoral research position in experimental petrology and geochemistry is available within the Department of Geological Sciences at Case Western Reserve University. We seek an experienced and highly motivated candidate with interests in material properties and chemical processes within Earth and planetary interiors. A Ph.D. in geoscience, materials science, physics, chemistry, or a related field is required. Experience with high-pressure experimental techniques is desirable. The successful candidate will be involved in setting up a multi-anvil and piston cylinder laboratory. Research opportunities include topics in high-pressure experimental geochemistry, chemical exchange across the core-mantle boundary, and isotope geochemistry of planetary materials.

The position is a one-year appointment with the opportunity to renew for an additional year, and is to be filled July 1, 2008 or as soon as possible thereafter. For further information, please contact Jim Van Orman.

Applicants should send a CV, a short statement of research experience and interests, and contact information for three references to Jim Van Orman (james.vanorman@case.edu).

39th LPSC Meeting

Several faculty and students are attending the Lunar and Planetary Science Conference in Houston, TX during spring break March 10-14, 2008.

Professors Ralph Harvey, Steven Hauck, and Jim Van Orman and graduate students Andreas Ritzer and Dejun Tan are attending the 39th annual Lunar and Planetary Science Conference in Houston, TX to present new scientific work and meet with colleagues. They are presenting and co-authoring papers over a wide range of topics from the earliest history of chondrite meteorites, analyses of micrometeorites and Apollo lunar samples, terrestrial analogs for Martian environments, to new results from the MESSENGER mission to Mercury. Graduate student Andreas Ritzer will be presenting his work on using non-spherical harmonic geophysical models for the Earth's moon.
