We are currently recruiting for summer and fall undergraduate researchers!

Interested in sedimentology and geochemistry? Read the article here: https://scse.d.umn.edu/earth-environmental-sciences-department/news/rock-paradox to learn more about our recent research.

Interested in petrology and geochemistry of volcanic rocks? You can read more about these topics in our 2016 Terra Nova paper on amygdaloidal pillow basalt Micro‐scale silicon isotope heterogeneity observed in hydrothermal quartz precipitates from the >3.7 Ga Isua Greenstone Belt, SW Greenland”: https://onlinelibrary.wiley.com/doi/full/10.1111/ter.12192 or our new GCA paper “Development of a mixed seawater-hydrothermal fluid geochemical signature during alteration of volcanic rocks in the Archean (∼2.7 Ga) Abitibi Greenstone Belt, Canada”: https://www.sciencedirect.com/science/article/pii/S0016703718301017

Congrats to Ugrad Stephen Hanson who will be presenting his research at the UROP Showcase, Nov. 15th, from 11 – 11:30 am in the Kirby Rafters

Undergraduate Earth and Environmental Sciences major Stephen Hanson has been working since January 2016 to characterize the mineralogy and textures of several samples of ~1.9 Ga chemical sedimentary rocks called iron formation from the Mesabi Iron Range in Minnesota. The goal of such a project is to identify and distinguish primary minerals from secondary ones via their textural relationships in order to better understand the geochemical conditions under which the original sediment that now makes up the iron formation was deposited. Understanding iron formation genesis has implications for constraining the geochemistry of the early Paleoproterozoic ocean, a time when early life was radiating and evolving, and levels of oxygen-sensitive elements in the oceans were likely changing. He will be presenting the results of this work as a poster at the upcoming UROP Showcase, Nov. 15th, from 11 – 11:30 am in the Kirby Rafters! Congratulations to all of his hard work this year!
