"In Sight of the Suture is the first overview of the pre-Carboniferous geology of the Isle of Man since the 1960s. It will be of prime interest to research workers in the geology of the Caledonian/Appalachian orogenic belt, to sedimentologists interested in deep marine processes…
Many present-day and ancient continental deformation systems appear to have formed due to significantly oblique relative plate motions. Transpression and transtension zones are formed where the oblique motions involve components of compression and extensions, respectively. This …
Using the Earth system approach, Steven M. Stanley shows how the Earth's ecosystem has developed over time, and how events in the past can help us to deal with present and future changes.
I investigated rifts in multiple stages of their formation, from the failed Mid-Continent Rift (MCR), to the active Red Sea Rift. Each rifting stage presents its own challenges but by studying each stage individually I have gained insight into the rifting process. The MCR, an an…
The Aegean Extensional Province (AEP) in Western Anatolia includes three major graben systems that have formed as a result of N-S tectonic extension in the latest Cenozoic. The 6 to 30-km-wide Alasehir-Gediz Graben (AGG) in the north contains ∼3-km-thick Miocene and Plio-Quatern…
The Philippine Sea Plate has been surrounded by subduction zones throughout Cenozoic time due to the convergence of the Eurasian, Pacific and Indian-Australian plates. Existing Philippine Sea Plate reconstructions have been made based primarily on magnetic lineations produced by…
By using arrival time data from the Indonesian Meteorological and Geophysical Agency (MGA), International Seismological Center (ISC) and United State Geological Survey (USGS), and the Centroid Moment Tensor (CMT) solutions of Harvard, I studied the tectonic features in north Sum…
The Atlas Mountains of North Africa, located in the African foreland of the Alpine mountain belts, comprise a 2,000 km long Cenozoic mountain chain whose development was guided by older Mesozoic rift structures. This dissertation examines one component, the Middle Atlas Mountain…
A key question in earthquake seismology is whether earthquake sources in different tectonic regions are functionally equivalent in terms of radiated ground motion. This thesis compares the apparent earthquake source radiation for six different tectonic regions covering Japan, Me…
This dissertation addresses two interrelated topics: interpretation of data obtained by a broadband phased three-component seismic array and development of new techniques to process and visualize these data. First, I present two techniques I developed for interactive, three-dime…
Gold has been mined in the Eastern Desert of Egypt since the time of the Pharaohs, yet the geologic setting of the gold mineralization, the structural controls, and its association with hydrothermal alteration zones is still not fully understood. A common application of remote s…
This dissertation includes three separate chapters, each demonstrating the interpretive utility of potential field (gravity and magnetic) geophysical datasets at various scales and in various geologic environments. The locations of these studies are the central San Luis Basin of…
