Petrography and stratigraphy of glacial drift, Mesabi-Vermilion Iron Range area, northeastern Minnesota Author: Winter, Thomas C., Cotter, R. D., Young, H. L. Year: 1973 Category: Report <p>Glacial deposits in the Mesabi-Vermilion Iron Range area consist of four major till units and associated glaciofluvial sediments. Particle-size data and pebble, heavy-mineral, clay-mineral, and percentage-soluble content were used in addition to field description of color and texture to describe and correlate the drift units.</p> <p>The lowermost till unit, basal till, occurs in only a small number of mines, but the mines are scattered across the entire Iron Range. The till is dark gray to dark greenish gray and brownish gray, sandy, silty, and calcareous. Pebbles are largely granitic and m Tags: usgs, Mesabi iron range Minnesota Source: ://pubs.usgs.gov/bul/1331c/plate-1.pdf
