Terrane Unit : WR
             Name : Wrangellia

      Description : Devonian to Permian arc volcanics, clastics and   
                    platform carbonates form the basement of          
                    Wrangellia; they are overlain by Triassic oceanic 
                    rift tholeiitic basalt, carbonate and Jurassic arc
                    volcanics and intruded by comagmatic plutons.     
                    Paleomagnetic data suggest displacement from low  
                    latitudes.  Amalgamated by the Late Jurassic and     
                    accreted to the continental margin in Late        
                    Jurassic and Cretaceous time.
