Diamonds, due to their inert and robust nature, encapsulate and preserve minerals, recording the mantle substrate in which they form. Forming in the subcontinental lithospheric mantle over a protracted period, diamonds provide snapshots of craton formation and mantle evolution over much of...

Myers, Brody

The nature of kimberlitic melts at mantle depths and their interaction with mantle wall-rocks is poorly constrained. This is due to the scarcity of mantle xenoliths and xenocrysts that have preserved this interaction without disaggregating during their transport to Earth’s surface. This thesis...

The Archean Yellowknife greenstone belt hosts world-class orogenic gold deposits including Con and Giant along with active prospects extending several tens of kilometers along the belt. Some common challenges in exploration for orogenic gold deposit include the nugget effect, which can lead to...

Lianas are woody thick-stemmed climbers that use host trees to reach the forest canopy. Studies have shown a remarkable increase in liana abundance in the last two decades, while others have shown that liana abundance is associated with detrimental effects on forest dynamics. Liana abundance...

Increased mass loss from the Canadian Arctic ice caps is associated with regional increases in the summer mean glacier surface temperature and the annual number of melt days. As a result of these changes , snow and ice melt are likely to occur at higher elevations and become more widespread,...

The middle Paleoproterozoic era (~2200–1800 million years ago) was host to some of the most significant perturbations in Earth’s elemental cycles, including the largest ever excursion of carbon isotope ratios in sedimentary rocks, known as the Lomagundi-Jatuli Event. This event has been linked to...

The lower Athabasca River valley in northeastern Alberta, famous for oil sands mining, was also the site of one of North America largest Ice Age floods. During deglaciation, a large proglacial lake, Lake Agassiz, drained catastrophically through the Athabasca River valley. This catastrophic flood...

During the Campanian-Paleogene, a regional basin extended from the Magdalena Valley in the west to the Llanos Basin in the east. Subsequently, the Llanos Basin was separated from the Magdalena Valley and became an independent depocenter from the Oligocene to the present. This study combines the...

The ~143 martian meteorites serve as the only rock samples from Mars that are presently available for study in a laboratory setting. These predominantly igneous samples are sourced from the near-surface units adjacent to craters formed during random, hypervelocity impacts of asteroids on the...

Earth’s changing climate poses a number of potential issues for people around the globe. It has become increasingly important for researchers to have the ability to collect good data and build accurate, robust climate models that can help influence the direction of policy makers to mitigate the...
