The Warren Lab at Stanford University studies the geochemistry and rheology of the Earth’s upper mantle, using samples of peridotite collected on land and at sea. Peridotite, the dominant lithology of the upper mantle, consists of olivine, orthopyroxene and clinopyroxene, with minor amounts of spinel and trace amounts of sulfides. In the oceans, peridotites are collected by dredging, diving or drilling at mid-ocean ridges and subduction zones. On land, peridotites are found as xenoliths and as orogenic peridotites and ophiolites.
We use a range of techniques to analyze peridotites, including field work, petrography, electron backscatter diffraction, electron microprobe, thermal ionization mass spectrometry, inductively coupled plasma mass spectrometry, ion probe, and synchrotron μ-XRF.
We are always looking for enthusiastic scientists to join our group! Enquiries should be directed to Jessica Warren.
- Undergraduates: support is often available through either Stanford or NSF funds to conduct summer projects in the lab.
- Graduate students: apply through Graduate Admissions in the Department of Geological and Environmental Sciences.
- Postdocs: contact Jessica with a project proposal. Full application for a postdoc position consists of a 1-2 page research plan (developed in consultation with Jessica), along with a cover letter, CV, and research statement.
