Chemical And Petrographic Survey Of Large, Igneous-Textured Inclusions In Ordinary Chondrites, Katherine Armstrong
Chemical And Petrographic Survey Of Large, Igneous-Textured Inclusions In Ordinary Chondrites, Katherine Armstrong
Dissertations and Theses
Our inventory of material from the early solar system includes large, igneous-textured inclusions in O chondrites, whose origin and relationship to their host meteorite is unclear. These inclusions occur in approximately 4% of O chondrites, and are mineralogically, petrographically, and chemically diverse. Petrographic and chemical data from 29 inclusions from 23 host meteorites were collected with optical light and scanning electron microscopy, allowing for the determination of major phase modal abundance and major element bulk chemistry. No correlation between any inclusion property and host meteorite type were found, but some trends were observed. Nine of the inclusions show strong evidence, …
