Structural and stratigraphic relationships of these lavas indicate that they were erupted in several distinct plateaus, each of which subsided centrally as rifting intensity shifted in time and place along the MRS (Green 1977; 1983), but age determinations so far sh

Hegels Logik und die Moderne PhysikIn 1856, David Owen first noted the existence of the Rough CreekShawneetown Fault System. Since that date, evidence has slowly accumulated to indicate the existence of a major polyphase rift complex crosscutting the east-central North American craton.

Sedimentary Fill of the 1100 Ma (Keweenawan) Midcontinent Rift System in the Lake Superior RegionIn the Lake Superior region, four “sequences” of sedimentary rocks reflect the tectonic-sedimentary framework immediately before, during, and after the 1100 Ma magmatic event that resulted in as much as 20,000 m of dominantly basaltic subaerial lava flows and large gabbroic intrusions (Behrendt et al. 1988).
