Chert conglomerate, chert-quartz sandstone, and pebbly mudstone of the westerly derived Earn sequence formed local massive channel deposits up to 200 m thick on submarine fans and in narrow grabens within a broad region of shale deposition. Extension and local contraction of the miogeocline during rifting or strike slip outboard of present preserved limits can explain (1) the derivation of Earn elastics from older miogeoclinal units, (2) local alkaline volcanism, (3) exhalite mineralization, and (4) tremendous thickness variations related to steep syndepositional faults.

Cassiar Terrane in Teslin map area is imbricated by at least two flat thrust faults. One emplaces Proterozoic to Cambrian clastics (Ingenika Group) above Devono-Mississippian chert conglomerate (equivalent to Earn Group). The conglomerate in turn is thrust over Mississippian carbonate, quartzite, volcanics and phyllite. Meagre evidence suggests the faults are west-directed, and possibly as old as Early Jurassic. The boundary between Kootenay and Stikine terranes is straighter than earlier mapped, making previously suggested dextral slip along this boundary kinematically more feasible. A small window or re-entrant of Cassiar Terrane beneath Kootenay Terrane is speculated.
