Investigating the Distribution and Source(s) of Lunar Volatiles
… N, He, Ne, and Ar) in a diverse suite of lunar mare basalts and soils, providing new insights about volatiles indigenous to the lunar interior, volatiles produced <i>in situ</i> at the lunar surface, and volatiles delivered to and implanted into the lunar surface. Simultaneous static-mode mass …

Petrological and rheological controls on volcanism to terrestrial planets
… including delamination under the Siberian flood basalts (Chapter 2), gravitational instabilities in the lunar magma ocean cumulates (Chapter 7), and thinning and convection due to giant meteorite impacts (Chapters 3 and 8), has lead to new models for melt production. These studies together show …

Experimental Constraints on Melting Processes in the Earth and Small Rocky Bodies
… sequence and petrogenesis of the young mare basalts collected by the Chang'e 5 mission and propose a model for melt generation in the Moon at ~ 2Ma. In Chapter 3, I estimate a minimum radius of ~1600 km for the Angrite Parent Body using near-liquidus equilibrium experiments. The …

Decline of the lunar dynamo
… after 3.56 Ga. Paleomagnetic data from several mare basalts indicates that the lunar dynamo surface dynamo field had declined to <4 [mu]T by 3.19 Ga. A lunar breccia may record evidence for a core dynamo field of at least ~770 nT at its formation age (<3.3 Ga). Samples acquire shock remanent …

Using Lunar Apatite to Assess the Volatile Inventory of the Lunar Interior
… however, are poorly constrained. Here, Apollo mare basalts were investigated to provide an accurate composition for which apatite is found to crystallize under lunar conditions. This composition was used high temperature, high pressure experiments which constrained volatile partitioning between …

An experimental and petrologic investigation of the source regions of lunar magmatism in the context of the primordial differentiation of the Moon
… dating to ~4.3 Ga, and the most recent known mare basaltic magmas dating to ~3 Ga. These samples provide insight into the petrogenesis of magmas and interior thermal state when the Moon was a hot, juvenile planet, and also during the last gasps of magmatism from a cooling planet. Chapter 1, …

Experimental simulation of Lunar Magma Ocean crystallization : insights into mantle composition and the source regions of lunar basaltic magmatism
Crystallization of the Lunar Magma Ocean has been empirically modeled and its products inferred from sample observations, but it has never been fully tested experimentally. Presented in this study is the first experimental simulation of lunar differentiation. Two end-member bulk Moon compositions …
