The interior structures of planetary bodies beyond the Earth are broadly unknown. Our observational capacity is largely limited to surface imagery from spacecraft. The work presented in this dissertation uses novel modeling methods of melt migration and melt focusing processes t…

The tectonic history of southwestern North America since the Late Eocene involves a complex transition from a subduction-dominated to a transform-dominated margin. Through this evolution, high elevations of orogenic plateaus and corresponding thick crustal welts were dramaticall…
This book explores the geotectonic evolution of the lithosphere beneath the Indian Shield, which comprises a collage of cratons variously bounded by mobile belts and palaeo-rifts. The lithosphere beneath these is fairly thin compared to other cratons worldwide, petrologically va…
The last deglacial history of the Antarctic Ice Sheet (AIS), the world’s largest freshwater reservoir, is important for monitoring the current AIS change and projecting the future sea-level rise trend. However, due to the lack of direct observational constraints on AIS last degl…
The topography and gravity measurements from missions to Venus and Mars are among a few data available to constrain models of the interior structure and dynamics of these planets. These measurements reveal various intriguing features whose origins have generated debates in the p…
This doctoral dissertation constitutes an integrated geophysical investigation of the lithospheric structure in the region of Libya. It is separated into three sections, each of which will be submitted to different scientific journals for publication. In the first part of the st…
Continental rifting is fundamental to the theory of plate tectonics, yet the force balance driving Earth's largest continental rift system, the East African Rift (EAR), remains debated. The EAR actively diverges the Nubian and Somalian plates spanning ∼5000 km N-S from the Red S…
Mechanisms for the formation of a foreland basin at the beginning of continental collision (Pliocene-Recent Australian continental foreland along the Banda orogen) and a post-orogenic, continental, Miocene extensional basin (Alboran Sea) are studied. Such a study investigates th…
