             Name : Slide Mountain

      Description : Oceanic marginal basin volcanics and sediments of 
                    Devonian to Late Triassic age which are basement  
                    to Quesnellia in southern B.C.  Included are      
                    chert, argillite, sandstone, conglomerate, mafic  
                    intrusions, basalt, alpine-type ultramafic rocks, 
                    carbonate rocks and local occurrences of          
                    blueschist and eclogite. Amalgamated by latest 
                    Triassic time and accreted to Ancestral North 
                    America in the Jurassic  In norhtern B.C. Permian
                    fusulinids are not found in coeval, co-latitudinal
                    cratonal rocks suggesting terrane movement from   
                    the south.
