Pre Technical Session

1) Banded iron formation of the Marquette District. Tuesday and Wednesday May 6 and 7 – Trip Leader: Tom Waggoner. This two day field trip of the Marquette Iron Range will examine the details of carbonate, oxide, and silicate banded iron formation. There will be field trip stops relevant to diagenetic alteration of BIF, supergene oxidation and enrichment of BIF, hydrothermal emplacement of hard iron ores and the underlying hydrothermal feeder system , and a brief overview of the stratigraphy of the Iron Range. FULL  

2) Archean-Paleoproterozoic unconformity at Silver Lake —seismites from the Sudbury impact? Wednesday May 7 – Trip Leader: Bill Cannon. Newly exposed outcrops created in 2003 by the draining of Silver Lake provide an extraordinary view of relationships along the Archean-Paleoproterozoic unconformity. The trip will examine sedimentary features in the basal Proterozoic sediments and an unusual set of brecciated and disrupted Archean basement blocks, sediment dikes, and drape folds that may have been caused by a powerful earthquake generated by the Sudbury impact event. An alternate interpretation for some of these features is paleoglaciation and periglacial processes. The trip will be an all day hike (3-4 miles round trip) over relatively easy terrane, mostly the old lake bed. FULL 

3) Geology of the Back Forty Project. Wednesday May 7 – Trip Leader: Tom Quigley and staff. This trip will provide an introduction to the geology of Aquila Resource's Back Forty Project, Menominee County, Michigan. The Back Forty deposit is a volcanogenic massive sulfide deposit with a 43-101 compliant resource of 6.6 million measured and indicated tonnes grading 5.3% zinc, 2.3 g/t gold, and 0.5% copper. Drilling to prove additional resources continues. The field trip will consist of an overview presentation, inspection of drill core, and a field visit to the Back Forty site.

4) Geology of the Eagle Project. Wednesday May 7 – Trip Leader: Jon Cherry, Andrew Ware and staff. This trip will provide an introduction to the geology of Kennecott Mineral's Eagle Project, a high-grade Ni-Cu magmatic sulfide deposit hosted in a dominantly peridotite intrusion of Keweenawan age. The field trip will consist of an overview presentation, inspection of drill core, and a field visit to the Eagle site. FULL

Immediately Following Technical Session

5) The Sudbury impact layer at the McClure locality. Friday May 9 – Trip Leader: Bill Cannon. This two-hour-long trip will examine the Sudbury impact layer about a ten minute drive from downtown Marquette. The McClure locality is a set of outcrops that provides a cross section of the Sudbury impact layer where it displays its maximum known thickness of 45 m. The outcrops here provide the most extensive and complete view of the impact layer. They extend from coarse basal breccias, through intermediate breccias and sandstone, containing abundant impact glass and both local and exotic rock fragments, to overlying black slate. Full as of March 6 - Can be put on a wait list.

Post Technical Sessions

6) Sustainable recovery of iron from the Marquette District. Saturday May 10 – Trip Leaders: Glenn Scott, Helene Lukey, Al Strandlie and CCI/CCMO staff. This field trip will cover the general geology, mining, processing and site reclamation at the Cleveland-Cliffs Michigan Operations including the Empire, Tilden and Republic Mines. Emphasis will be on the overall production process and the mitigation of potential environmental impacts at major pellet producing facilities. This trip will not provide details of iron formation, so please register for Trip 1 if you want to delve into iron formation genesis. Only one opening as of April 9

7) Geology of the Keweenawan BIC Intrusion. Saturday May 10 – Trip Leader: Dean Rossell. This field trip will examine the geology and geologic setting of the BIC intrusion, near L'Anse. The BIC intrusion consists of peridotites, pyroxenites and gabbro. It is under exploration by Kennecott Minerals Company and will be examined in outcrop and drill core. Field trip stops will also include some of the surrounding country rock.
Full - Can be put on a wait list

8) Geology of the Eagle Project. Saturday May 10 – Repeat of Trip 4 Full - Can be put on a wait list
