“…The oldest predominant age peak in the 'younger' zircon population of detritus from the composite Laurentian margin is 511 Ma, which could correspond with the age of the oldest suprasubduction zone rocks of the peri-Laurentian arcs in Newfoundland, the Twillingate trondhjemite (Elliott et al 1991), and older volcanic rocks of the Sleepy Cove Group in the Lushs Bight oceanic tract ). However, fifteen concordant detrital zircon grains ranging in age from 529 to 617 Ma, and four grains ranging from 786 to 819 Ma are present in these three samples (Figs.…”

“…Elsewhere this deformation produced inclined or recumbent F 1 folds and associated bedding-parallel S 1 cleavage in the Badger Group and underlying older rocks (e.g. Elliott et al 1991). Structural transport direction varied, but generally was to the southeast or south taking into account the reorientations caused by younger deformation events (van der Pluijm 1986;Lafrance and Williams 1992;Kusky and Kidd 1996;O'Brien 2003).…”

“…Radiometric dates on the underlying volcanics and on cross-cutting dikes as well as fossil data [14,20] indicate that both the Springdale and Wigwam redbeds were deposited in the Llandoverian to Wenlockian. Radiometric results from undeformed dikes indicate that folding of the redbeds is also Silurian in age [18]. Concurrent with and preceding regional folding are episodes of both sinistral and dextral strike-slip faulting [21], that are thought to result in local rotations about vertical axes.…”
