TIME-RESOLVED RAMAN SPECTROMETER FOR IDENTIFYING FOSSILIZED ORGANICS AND INTERPRETING DEPOSITIONAL ENVIRONMENTS AND ALTERATION HISTORIES OF PLANETARY

Project: Research project

Description

Statement of Work JPL SURP: Co-I Jack Farmer will act as PhD advisor for Svetlana Shkolyar, overseeing sample analysis in labs at ASU. The ASU effort will provide a well-characterized sample suite for analysis using laser Raman facilities in PI Jordana Blacksbergs laser Raman lab at JPL. Study samples will emphasize aqueous sedimentary rocks exhibiting different types of kerogen preservation, but will also include other lithotypes (e.g. mafic igneous lithologies, impact ejecta and meteorites), representative of a broader range of exploration targets (and potential Raman applications) at Mars, the Moon and elsewhere in the Solar System. The following analytical methods will be used to create a context for the analysis by laser Raman: Electron microprobe surveys (for identifying and mapping of major and minor elements), powder x-ray diffraction (for determinative mineralogy, fluorescence microcscopy (localization and identification of kerogen), and light and scanning electron microscopy (characterizing microtextures and paragenesis of samples in thin section). Results for lab analyses from ASU will be used to create a context for laser Raman analysis at JPL. Prof. Farmer will participate in team telecons, attend team meetings at JPL and assist with the preparation of manuscripts for publication.
