If you do not know exactly where your specimen came from in this area, then place it here rather than guessing.

An area containing copper bearing interbedded basalt and conglomerate equivalent to the formations in the Keewenaw area of Michigan. The rocks in this area have been dated at approx. 1100Ma and are thought to represent the most complete record of the rifting event that created these rocks (Swanson-Hysell,N.L et al. 2014)
