Structure And Metamorphism Of The Talc Creek Area, Harrison Lake B.C., Minda L. Troost

WWU Graduate School Collection

The Slollicum and Cogburn terranes, metamorphosed country rock within the southern Coast Plutonic Complex, are juxtaposed along a thrust fault together with large slabs of ultramafic rock. The structure and metamorphism along and near this fault are the focus of this study.

Three periods of deformation (D₁-D₃) affected the study area. D₁ structures consist of penetrative foliation and lineations that are attributed to thrust stacking of the Slollicum and Cogburn terranes. Foliation, which parallels the fault contact, dips to the northeast at moderate to steep angles. Lineations have mainly down-dip orientations. D₂ structures record …
