Abstract

This project was carried out under the supervision of Dean Peterson, Vice President of Exploration at Duluth Metals with the goal of creating a higher-resolution bedrock map of the Gafvert Lake area. The area was last mapped in 2003 at the 1:100,000 scale by the Minnesota Geological Survey (Jirsa and Boerboom, 2003). Mapping was carried out over five days by eight students for the 2013 Precambrian Field Camp. Six hundred and seventeen outcrops were mapped by hiking and lakeshore canoe mapping. The final map incorporated over 1,500 outcrops from historical work in the area. Emphasis was placed on defining the structure of an Archean stratovolcano within the Vermilion Greenstone Belt.
