We live in an era of big data, brought on by the advent of automatic large-scale data acquisition in many industries. Machine learning can be used to take advantage of large data sets, predicting otherwise unknown information from them. The Minnesota County Well Index (CWI) data…

A Faixa Piritosa Ibérica é uma das províncias metalogenéticas mundiais mais estudadas e a sua prospecção e exploração extensivamente documentadas. Mesmo após mais de 5000 anos de contínua exploração mineira, as reservas demonstradas continuam excepcionalmente altas, embora confi…
In his great work on fossil bones (1812), Georges Cuvier compared our ignorance of geohistory to our conceptual mastery of the heavens. Several centuries of research had “burst the limits of space” and drawn back the curtain on the hidden mechanism of the universe. Yet deep time…
Deepwater clastic deposits of the Late Miocene Isongo Formation, located 50 km northwest of Bioko Island, characterize a sand-rich transient fan system developed in response to incipient structural growth on the continental slope. Approximately 1200 ft (366 m) of conventional co…
This thesis presents the vertebrate paleontology of the Early Pleistocene Daka Member, Middle Awash, Ethiopia, including its geological and chronological contexts. Focused work on the Daka Member began in 1981 under the guidance of Desmond Clark and Tim White, and intensified be…
Rocks exposed south of the MMT in the lower Swat terrane, Pakistan represent the northernmost margin of the Indian plate. These rocks comprise Precambrian-Cambrian(?) basement gneiss (Swat Gneisses) and Paleozoic cover-sequence (Alpurai Group metasediments). Anatectic tourmaline…
Lake basins contain depositional systems whose stratigraphy and sedimentology are highly influenced by allogenic and authigenic processes. Identifying the relative roles of these controls is complicated in settings where both tectonic and climate influences control sediment inpu…
During the Early Cretaceous a regionally extensive cover of dominantly siliciclastic sediments was deposited across the North African continental margin. Historically, these siliciclastic sediments have been considered to be a relatively homogeneous lithofacies known as the ‘Nub…
Red siliciclastics and evaporites of Permian Nippewalla Group in mid-continental US were deposited in western equatorial Pangea. Previous studies of these rocks record Permian air temperatures as high as 73 °C, saline lake waters with a pH as low as ~1, and sedimentology that sh…
This thesis investigates the use of growth stratigraphy in deepwater environments to determine fault kinematics and reservoir distribution in the Niger Delta and assess earthquake hazards associated with blind-thrust faults in the Santa Barbara Channel, California. Chapter 1 ana…
This study provides insights into the age, extent, and depositional history of a 23 kilometer-long sequence of eolian sands that overlies a paleosol of previously undetermined age along the southwestern margin of the Delmarva Peninsula, VA. References in past literature and maps…
At the highest level, this dissertation investigates marine systems from a geochemical and sedimentological perspective through the undertaking of six distinct and only somewhat tenuously interrelated contributions. Nonetheless, the work detailed herein might be thought of as fi…
Subduction zones host the world’s largest earthquakes, but seismic slip is only one style of deformation along the subduction interface. The deformation processes above and below the seismogenic zone are equally fundamental to understanding how relative motion is accommodated du…
The Giant Foresets Formation in the Taranaki Basin defines the present-day continental margin of the west coast of New Zealand’s North Island. Using regional 2D and 3D seismic datasets calibrated with exploration wells, this thesis presents a new highresolution seismic stratigra…
On decadal time-scales, most rivers remain relatively stable, changing through shifting bars and eroding cutbanks. On longer time-scales, rare but radical channel repositioning events are documented on rivers around the globe. This repositioning process, called avulsion, has cau…
I present the results from the first geological map of the Derain (H-10) quadrangle of Mercury and in-depth studies of features identified in the map.
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…
