    • Density measurements on Precambrian rocks in the Iron Mountain-Menominee region, Michigan-Wisconsin

    Metadata Updated: October 29, 2025

    The U.S. Geological Survey (USGS) collected rock density measurements to help understand causative sources of gravity survey anomalies in the Iron Mountain-Menominee region, Michigan-Wisconsin. The measurements were determined from rock samples collected on outcrop and in drill core. The measurements facilitate the interpretation of gravity anomalies and help map the distribution of Precambrian rocks in the region.
