Provenance and Pb isotopic ages of lunar volcanic and impact glasses from the Apollo 17 landing site

Norman, Marc; Adena, K J D; Christy, Andrew


Glassy spherules found in the lunar regolith can be used to investigate the volcanic and impact history of the Moon. Here we report the first study combining petrography with microbeam geochemical data for major-element, trace-element and Pb isotopic compositions of individual spherules that were separated from a sample of regolith collected at the Taurus-Littrow Valley on the Moon. Petrographic characteristics of 216 spherules were established by optical and electron microscopy. About half of...[Show more]
