Martian near-surface materials in shergottite meteorites: Searching for evidence from Tissint shock-melt pockets
DownloadSpring 2016
Three thin sections of the Tissint Martian meteorite were examined by an array of in situ techniques in order to assess the possibility that a geochemical signature characteristic of the Martian near-surface has been preserved within the meteorite. Tissint is a recent basaltic Martian fall that...

Repair scars, traces left by a failed attack on a prey item, provide direct evidence of predation in the fossil record modern systems without preservation or observation of predation events themselves. Counting repair scars and calculating repair frequencies, the number of scars in an assemblage...

This dissertation focuses on problems and progress in studying crushing predation on gastropods in the Modern and the fossil record. Although crushing predation tends to be destructive, it is possible to gather data on crushing predation from multiple angles. Chapter 2 applies an ichnotaxonomic...

Biochar has received significant attention as an innovative sorbent for treating heavy metal contamination due to its high surface reactivity and sorption capacity, ease of manufacture and low production cost. Most studies involving chromium removal from solution by biochar have focused on...

Phlogopite, an alkali-rich and water-bearing mineral, is a common phase in the Earth’s upper mantle. Its breakdown could generate melts or stabilize fluids that will metasomatize mantle rocks. To date, the effect of CO2 on phlogopite stability remains unconstrained. To evaluate the stability of...

Meso- and Neoarchaean Banded Iron Formations of the Slave Craton, NW Canada: Seawater Chemistry, Source Characteristics, Depositional Setting and Age Constraints
DownloadFall 2016
Banded iron formations (BIFs) are iron- and silica-rich chemical sedimentary rocks that have been widely used as a proxy for the chemical and redox composition of Achaean seawater. Within the Slave Craton (Northwest Territories, Canada), two different BIF deposits exist: (1) an ~ 2.85 Ga unit...

Carboxylated macromolecules such as alginate and glycoproteins are abundant components of modern shallow marine sediments where they are secreted by bacteria and marine infauna. Both organic compounds are proton and metal reactive; hence, they have the potential to facilitate metal sorption and...

Metamorphic devolatilization, mineral reaction, and fluid alteration in the Mica Creek area (British Columbia, Canada) inferred from whole-rock and mineral nitrogen isotope signatures
DownloadSpring 2019
The Neoproterozoic Horsethief Creek Group metasedimentary rocks in the Mica Creek area (British Columbia, Canada) are an important supracrustal sequence in the Canadian Cordillera. They contain a continuous range of metamorphic grades from slate, progressively to schists in the biotite, garnet,...
