Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Mesoproterozoic
1000 - 1600 Ma



ID: 3190266
Mesoproterozoic volcanic rocks

Age: Mesoproterozoic (1000 - 1600 Ma)

Comments: Mid-Continent Rift

Lithology: Bimodal volcanic rocks

Reference: Chorlton, L.B. Generalized geology of the world: bedrock domains and major faults in GIS format: a small-scale world geology map with an extended geological attribute database. doi: 10.4095/223767. Geological Survey of Canada, Open File 5529. [154]

Stenian
1000 - 1200 Ma



ID: 2739452
Gabbroic rocks of Keweenawan affinity

Age: Stenian (1000 - 1200 Ma)

Description: gabbro, anorthosite, granite, peridotite

Comments: This unit was originally called "gabbros of uncertain affinity" on the Sims (1992) map. Since that map was published, several of these bodies have been dated and appear to be of Keweenawan affinity. This unit includes gabbros and anorthosites in the Amnicon Intrusion, the Mellen complex, and the peridotiite at Upson, MI as well as individual bodies (the unexposed Clam Lake, Round Lake intrusions). These units are now known to be of Keweenawan affinity. The gabbro associated with the Mellen complex has been dated by U-Pb zircon dating yielding a date of 1102.0 +/- 2.8 Ma and the Mellen granite has a U-Pb zircon date of 1100.9 +/- 1.4 Ma (Zartman and others, 1997, U-Th-Pb zircon ages of some Keweenawan Supergroup rocks from the south shore of Lake Superior: Canadian Journal of Earth Sciences, v. 34, p. 549-561). A rhyolite associated with the Amnicon pluton has a U-Pb zircon date of 1101.8 +/- 6.7 Ma (C. Isachsen, Univ. of Arizona, unpublished data, 2003) Original map source: Cannon, W.F., Kress, T.H., Sutphin, D.M., Morey, G.B., Meints, Joyce, and Barber-Delach, Robert, 1997, Digital Geologic Map and mineral deposits of the Lake Superior Region, Minnesota, Wisconsin, Michigan: USGS Open-File Report 97-455 (version 3, Nov. 19
