U-M 2014 UP Geology Field Trip

28 August 2014

Harvey Quarry

A quick stop to check out the fault exposed in the Harvey Quarry, separating Mona Schist from the Menard Quartzite. Good example of mylonite here.

At this stop on Presque Isle, we look at what has been interpreted as a paleosol. The basal conglomerete sites in the air above the suggested regolith, where a softer layer -- the paleosol -- has been eroded out.

Basal Conglomerete

Stopping to look at the basal conglomerete layer exposed here in the Jacobsville.

Joint Sets

Discuss ing joint sets in mafic rocks exposed along the Lake Superior shoreline.

Sulfide Mineralization

Exploring an area of sulfide mineralization at Presque Isle. Silver mining was attempted, however, after 3-tons of ore removal the source dwindled out and operations shutdown.

Marquette Ore Docks

We've seen various examples of mines on this trip. Last night we camped close by to where the product is shipped out across the Great Lakes. Coal is also delivered here to supply the power plant in the background.

Jacobsville Sandstone

Another trip to the Jacobsville Sandstone. This time in Presque Isle Park in Marquette. Running through how to characterize rocks and interpret environments again.

Field trips are a critical and integral component of geoscience education. They provide students with unequaled opportunities for exploring and understanding geological principles first-hand, outside of the classroom, at real-world scales.

Such trips, however, are expensive endeavors. While students themselves bear a portion of the costs, we rely on grants and donations to cover the majority of the trip's costs. This helps to ensure an affordable experience open to all students.

This year's field trip is supported by a generous contribution from an anonymous donor.
