Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen
Fluid Properties In The Formation Of High-Grade Iron Ore In Northern Minnesota, Elizabeth Drommerhausen
Journal of Undergraduate Research at Minnesota State University, Mankato
The Mesabi Iron Range in Northern Minnesota has been a major producer of iron ore for over 100 years. Production has been from the 1.85 – billion-year –old Biwabik Iron Formation, an iron-rich sedimentary rock that is tilted gently to the south. Most of the known high-grade ore lies near the surface and has been already mined. Determining whether more high-grade ore may lie at depth could have significant economic impact on the mining industry in northern Minnesota. To evaluate the likelihood of finding more high-grade iron ore deeper underground, it is important to determine the source of the fluids …

The Blue Earth River (BER) watershed covers approximately one million acres of south-central Minnesota and northern Iowa. Modern farming practices have led to the loss of over 90 percent of the watershed's original wetlands. Corresponding changes in runoff and stream flow have led to dramatically reduced water quality in the BER's main stem following most precipitation events. The purpose of this research is to examine the relationships among precipitation, infiltration, base flow, and runoff in the Blue Earth River watershed basin.
This study developed a calibrated numerical hydrologic model for BER watershed using the distributed flow model, Vflo™. The model …
