“Pink” Mg-spinel is a rare mineral among rock samples returned during the Apollo missions and is typically associated with the lunar highlands Mg-suite (a small …
Thermal evolution of the planet interior is a fundamental problem in Earth and planetary sciences. Geothermobarometers and geospeedometers are powerful tools in studying the thermal …
This body of research uses numerical models to investigate the dynamics of melt generation in the asthenosphere, accumulation at the base of the lithosphere by …
Abstract of Experimental and Field Constraints on the Physicochemical Evolution of the Lunar and Terrestrial Mantles, by Nicholas Dygert, PhD., Brown University, May 2015. This …
The first three chapters of this thesis are focused on experimental determinations of noble gas solubility in a variety of materials relevant to partial melting …
In this dissertation, I present a large geochemical data set of submarine glass, melt inclusions and whole rock collected from across the Galapagos Archipelago to …
Orbital and landed investigations of Mars have revealed a variety of secondary minerals on the surface consistent with past surface or subsurface liquid water and …
This work is perhaps the first major study integrating mineralogical and morphological properties of lunar impact melt deposits using the new generation remote sensing data. …
This work presents novel Miocene – Pliocene (13 - 2.6 Ma) sea surface temperatures (SST) from the Mediterranean Sea, North Atlantic, South Atlantic and North …
The nitrogen and oxygen isotopic composition of nitrate in ice cores offers unique potential for examining reactive nitrogen oxide (NOx) budgets and oxidation chemistry of …
There is substantial geologic evidence, including extinct valley networks and paleolakes, for a period of increased aqueous activity on the surface of Mars prior to …
Global warming due to anthropogenic contributions is a major concern scientifically, politically, and socially. Therefore, characterizing oceanographic and climatic changes under past warm conditions is …
The rheology of the lower continental crust profoundly affects our understanding of crustal dynamics, lithospheric curst/mantle coupling, and seismic hazards. However, the effect of processes …
