Biographical Information

I was born and raised along Michigan's west coast. I received my BS and MS degrees in geological sciences from Michigan State University.

Research

Chapter 1:  Stratigraphic architecture of the Punta Barrosa Formation, Magallanes–Austral Basin, southern Patagonia.

This study is focused on the stratigraphic architecture of well-exposed deep-water lobes deposited in a retroarc foreland basin setting in the Cretaceous-aged Magallanes–Austral Basin of southern Patagonia. Contemporaneous shallow marine outcrops are also preserved in the study area and thus permit a comparison of ancient deep-water basinal deposits and their shallow marine equivalents. Results from this investigation will further our understanding of the nature of deep-water lobes and the depositional systems that feed them.

 

Chapter 2:  Sedimentology and stratigraphy of the Cerro Toro Formation, Magallanes–Austral Basin, southern Patagonia.

The Cretaceous Cerro Toro Formation includes a well-studied succession of conglomerate deposited in a deep-water axial foreland basin channel system. However very little is known about the sedimentology and stratigraphy of the more proximal deposits that served as sediment conduits for the coarse-grained channel-fill deposits and whether or not such systems would provide appealing reservoir potential. To address these uncertainties, this study documents the stratigraphic architecture of the northern-most known outcrops of the Cerro Toro Conglomerate.

 

Chapter 3: Orogen-parallel trends in stratigraphy and provenance to assess sediment dispersal patterns into a tectonically active deep-water basin.

Retroarc foreland basin systems are “classically” thought to have Deep-water depositional systems that are short-lived phases which quickly evolve into shallow and non-marine systems.  However, the Magallanes–Austral retroarc foreland basin of southern Patagonia preserves along-strike variations in a wide range of depositional settings that all contribute to filling a retroarc foreland basin that culminates in at least 4 kilometers of deep-water stratigraphy over a span of nearly 20 million years. This chapter is focused on larger scale trends in the regional stratigraphy and provenance to determine the influence of tectonic inheritance on the evolution of sediment dispersal patterns into a long-lived deep-water foreland basin.

 

Chapter 4:  The evolution of geochemical signatures preserved in modern sediment, Great Valley, California: Tracking the effects of provenance dilution in longitudinal transport systems.

Longitudinal (orogen-parallel) transport systems are common components of sedimentary basin fills – including deep-water depositional systems. Many studies of ancient basins apply provenance techniques to gain a better understanding of source-to-sink relationships of sediment transport systems. This investigation examines the effects of dilution for a range of provenance applications from non-marine sources to deep-marine sediment sinks. Data are collected from modern sediment in California and these results will serve as an analogue to provenance trends observed in ancient longitudinal transport systems.
