From the dust particles to tectonic plates: New views from high-resolution paleomagnetism

April 19, 2021
General Seminar
Dr. Roger Rennan Fu, Harvard University
Magnetic fields are thought to govern the lifetime of protoplanetary disks by mediating the inward accretion of gas. At finer scales, magnetic instabilities may have led to turbulent eddies where the first planetesimals formed.
Composition of the Earth’s Core: From Enigma to Conundrum

April 22, 2021
Thematic Seminar
Dr. Jackie Li, University of Michigan
This lecture will start with a broad overview of the composition of the Earth’s core, focusing on the source of our knowledge and associated uncertainties.
Light elements in the Earth’s core

April 29, 2021
Thematic Seminar
Dr. Lidunka Vočadlo, University College London
There are many unresolved problems concerning our understanding of the Earth’s core; even fundamental properties, such as the internal structure and exact composition of the inner core, are poorly known. Although it is well established that the inner core is made of iron with some alloying elements, the structural state of the iron and the nature of the light elements involved remain uncertain.
Exploring for diamonds and what they tell us about how the Earth works

April 29, 2021
Neighborhood Lecture Series
Dr.Graham Pearson, University of Alberta
Finding and evaluating diamond deposits is one of the hardest tasks in mineral resource development. In this talk, we will delve a little into the techniques used to find diamonds and how to evaluate the deposits. We will then examine why diamonds—the deepest derived of all natural materials—are unique in their ability to illuminate processes taking place over 700 km beneath Earth's surface, and up to 3.5 billion years back into its history.
