The Geology and Geomorphology of the Duluth Area

Monday, April 15, 2024 | 9:00 am - 4:30 pm

Price: $85.00

The bedrock geology of the Duluth area includes two major sequences of Precambrian rocks. To the immediate south are ~1.8-billion-year-old Paleoproterozoic metasedimentary rocks of Thomson Formation that were deformed into east-west trending, upright folds during the Penokean orogeny. Following 700 million years of weathering and erosion, the North American craton began to split apart forming the 1.1-billion-year-old Mesoproterozoic igneous and sedimentary rocks of the Mid-Continent Rift. The rift produced voluminous eruptions of basaltic lavas (up to 30 kilometers thick) on the Earth’s surface forming the lavas of the North Shore Volcanic Group that are so well exposed along the north shore of Lake Superior. In addition to eruptions of basaltic lavas on the surface, the Mid-Continent Rift produced voluminous magmas that solidified at depth to form comagmatic, sill-like mafic intrusions such as the well-known, and metalliferous (Cu-Ni-Co-PGE) troctolitic intrusions of the Duluth Complex. Atop these Precambrian rocks and following 1.1-billion-years of weathering and erosion is a thin veneer of unconsolidated glacial sediments and landforms.

This field trip will explore this >1.8-billion-year-old history of the Lake Superior area in general, and the Duluth metropolitan area in detail, as told by numerous bedrock geology exposures throughout the region. Also, we’ll explore the geomorphology of Duluth and how the rugged landscape was formed and shaped by the underlying bedrock geology.

Attendees should wear appropriate outdoor attire for all weather conditions, rain, sleet, snow, or 20 below! Hiking boots, gloves, and many layers.

Notebooks, pencils, and a sack lunch are provided.

Talon Metals – Tamarack Nickel Project - SOLD OUT

Monday April 15, 2024 | 8:00 am – 1:00 pm     

Cost: $65.00

Join us on a field trip to see the Talon Metals Tamarack Nickel Project. The Tamarack Nickel Project is currently the only development-stage high-grade nickel project in the US. On this tour, participants will get the opportunity to visit the Talon core shed and exploration site to learn more about Talon’s in-house exploration process, innovative approaches, and goals for providing a domestic source of nickel for the US EV battery supply chain. 

Attendees should wear close-toed shoes (steel toe preferred) and dress for the weather. All other required PPE are provided. You may use your own hard hat/eye & ear protection. Lunch not included.


Tour Schedule:

7:30 am – Check-in

8:00 am – Departure from DECC

9:00 am – Arrive at Talon Metals

Noon – Depart Talon Metals

1:00 pm – Arrive back at the DECC
