Understanding Hydrogen Variations In Silicate Glasses As A Result Of Degassing: Fire-Fountaining On The Moon And Earth, Erin M. Recchuiti

Masters Theses

Volatiles, particularly hydrogen, play a key role in volcanic eruptions, especially explosive eruptions like fire-fountaining [e.g., Saal et al. 2002; Dixon 1997; Arndt & von Engelhardt 1987; Yoder 1976]. Discerning volatile abundance and behavior during ascent and eruption can aid in understanding the source melt and primary volatile content of planetary interiors. Volcanic glasses are samples closest to the primary melt, as they quench quickly enough to limit fractionation or crystallization. This is paramount for volatile studies, especially pertaining to water as its constituents are oxygen and hydrogen. Hydrogen is the most volatile element and one of the first to …


From The Mantle To The Moon: Studies Of Kimberlitic Ilmenites, Meteorite Fusion-Crusts, And The Moscoviense Basin On The Moon, Kevin Glenn Thaisen May 2012

From The Mantle To The Moon: Studies Of Kimberlitic Ilmenites, Meteorite Fusion-Crusts, And The Moscoviense Basin On The Moon, Kevin Glenn Thaisen

Doctoral Dissertations

I have explored a variety of geologic problems in the course of the chapters contained within this dissertation. These include a study relating to the fusion crusts on meteorites, an impact basin of the Moon, and Siberian kimberlitic ilmenites. The first chapter explores two assumptions commonly employed in meteorite analysis; that fusion crust compositions represent the bulk-rock chemistry of the entire meteorite and that the vesicles within the fusion crust result from the release of implanted solar-wind volatiles. Neither of these assumptions was found to hold true in that study. The second chapter explores the unusual nature of the Moscoviense …
