What we do

Our group works to solve Precambrian problems at the intersection of sedimentary and hydrothermal processes, using tools that span the macro- to micro-scale.
Field work

Field work

Traditional mapping

We primarily work in Precambrian terranes in northern Minnesota and Canada.

Drill core

Drill core

Portable x-ray fluorescence analyzer

We are located close to the Department of Natural Resources drill core library, allowing us to tackle stratigraphy, sedimentology, and alteration projects at the basin-scale.

Micro-scale techniques

Micro-scale techniques

Microscopy, analytical geochemistry

Our lab houses transmitted and reflected light microscopes, and sample preparation equipment for element and isotope analysis. On campus, we have access to a shared instrument laboratory with SEM, XRD, and XRF capabilities.
