Learn More About Dr. Pufahl
Peir Pufahl (Ph.D) leads an international, multidisciplinary research program focused on the sedimentology and economic geology of bioelemental sediments. Bioelemental sediments include phosphorite, iron formation, and chert, which are precipitates of the nutrient elements P, Fe, and Si. These rocks are economically important because they are used in the manufacture of fertilizer and steel, and are important hydrocarbon reservoirs. Since bioelemental sediments actively participate in Earth system evolution they record the interplay between climate, meteorology, and ocean circulation on nutrient cycling and environmental change.
My students use a process oriented, interdisciplinary approach to solve sedimentologic problems that result in manuscripts published in high-quality peer-reviewed journals. International and Canadian-based thesis research interprets the sedimentology, stratigraphy, and geochemistry of bioelemental sediments to understand Earth history and create state-of-the-art exploration models for industry.
It is an exciting time for my research group with the construction of our new CFI-funded lab, which focuses on the petrogenesis of sedimentary ore deposits. Working closely with Acadia’s Office of Advancement and industry to establish a NSERC Senior Industrial Research Chair will help Canada become a global leader in fertilizer research.
