Compositional And Topographical Characterization Of Carbonaceous Chondritic Meteorites Moss And Murray Using Micro-Raman Spectroscopy And Sem/Eds, Aaron Stokke
All Graduate Theses, Dissertations, and Other Capstone Projects
Carbonaceous chondritic meteorites are considered some of the most primitive surviving materials from the formation of our solar system. Thus, these objects can provide information about planet formation through their physical properties (such as structure, composition, and morphology) which can be characterized using microscopy and spectroscopy techniques. In this work, the analytical methods of Raman spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and optical microscopy are applied to determine the mineralogical, topographical, and elemental compositions of two carbonaceous chondritic fragments: Moss and Murray. Both samples were comprised of chondrules and matrix while Moss contained chondrule rims and Murray …
Comparative Study Of Cv3 Carbonaceous Chondrites Allende And Bali Using Micro-Raman Spectroscopy And Sem/Eds, Raka Paul
All Graduate Theses, Dissertations, and Other Capstone Projects
The birth of the solar system (over 4 billion years) is speculated to have happened from a nebula, swirling and compacting in localized regions to eventually form the Sun and planets. This complex process consists of numerous changes and intermediary steps, yet to be fully understood. Carbonaceous chondritic meteorites are relics of that process and therefore have potential to reveal information about the formation history. Several theories have been formulated linking their composition to planet formation. This study focusses on two carbonaceous chondritic specimens, Allende and Bali, both of the group CV and petrologic type 3. CV meteorites are abundant …
