Acadia ALERT - Full Campus Closure Due to Weather

Today, February 16, 2024 at 2pm, Acadia University will close the entire campus, with the exception of residences and Wheelock Dining Hall, due to the forecasted weather. Wheelock Dining Hall may adjust their hours due to the weather and any change in hours will be communicated through Residence Life. The Acadia Athletic Complex, Vaughan Memorial Library, KC Irving Environmental Science Centre and the Manning Memorial Chapel will be closed in addition to the rest of the campus. Any events scheduled for today will be postponed or canceled.

The campus will remain closed until 12pm on Monday February 17, 2025. An update on campus conditions will be provided no later that 11am on Monday. Should conditions allow campus will reopen at 12pm.

Updates will be posted on www.acadiau.ca and pre-recorded on Acadia’s Information Line: 902-585-4636 (585-INFO) and on 585 phone system voicemail. If you need emergency-related information, please contact the Department of Safety and Security by dialing 88 on all 585-phone systems, or by calling 902-585-1103.

'Exploring Metamorphism, the Global Carbon Cycle and Critical Mineral Deposits Through Magmatic Fluid-Rock Interactions’

11:30am-12:30pm

 

Fluids migrating through the crust drive mass and chemical transfer across different Earth spheres. These processes affect metamorphism, geochemical cycling, and critical mineralization to varying degrees across different spatial scales. In the upcoming research talk, I will first share a series of interconnected stories about fluid-rock interactions in metacarbonate rocks. The journey begins with phase equilibria, a framework where specific mineral assemblages offer clues about formation temperature and fluid composition in skarn systems. From there, we move to southern Tibet, where a case study shows how magmatic fluid infiltration into carbonate rocks may influence the global carbon cycle and Earth’s long-term climate. The story then shifts to the Sierra Nevada Batholith, where I examine how factors like rock rheology and depth influence fluid migration dynamics and their broader impact on carbon cycling.

Fluids also transport strategic metals and form chemically zoned accessory minerals (e.g., apatite) in some mineral deposits. If these zoning patterns correspond to multi-episode ore-forming events, petrologic tools like diffusion speedometry and geochronology can help constrain the duration of these events. I will discuss future work on how this idea can be tested using IOA deposits in the Great Bear magmatic zone of the Canadian Shield. Finally, I will discuss how wetting properties of fluid might affect the spatial distribution of mineral deposits.

Together, these stories reveal how fluid-related patterns preserved in rocks hold valuable insights across multiple fields, connecting petrologic processes to planetary habitability and resource formation.
