... on the prospect is structurally controlled and occurs in siliceous dolostone near the top of the folded and faulted Coppercap Formation, directly beneath an unconformity separating two local members of the Sayunei Formation (Rapitan Group). The copper was emplaced in tectonically fractured dolostone, precipitated...

... investigated the ca. 735 Ma Coppercap Formation in northwestern Canada, a unit that preserves large shifts in carbonate δ 13 C values that have been utilized in global correlations and have canonically been explained through large shifts in organic carbon burial. Under the backdrop of these δ 13 C shifts, we...

to CP6 are members of the Coppercap Formation (see Fig. 3 ). Stratiform copper mineralization occurs within CP1, the transition zone. RR4 is the hematitic sandstone and siltstone dominated distal alluvial fan facies of the Redstone River Formation. RR4 has a minimum true thickness of approximately 1,200

The true polar wander (TPW) hypothesis for the BSS explains differences in paleomagnetic pole positions as the result of oscillatory TPW ( Maloof et al., 2006 ; Swanson-Hysell et al., 2012 ). If observed shifts are the result of TPW (there and back...
