Tectonic Unit: CDR
	 Name: Rocky Mountains

  Description: resistant dolomite, limestone and local sandstone 
	       interbedded with recessive red, green and grey    
	       shale and detrital carbonate that together form   
	       several carbonate-shale grand cycles.  These pass 
	       westward into offshelf shale, siltstone and       
	       thin-bedded carbonate with minor alkalic tuff,    
	       breccia and amygdaloidal basalt of Cambrian (Cv), 
	       Cambro-Ordovician (COv), Silurian (Sv) and Devonian
	       (Dv) ages but mainly of Ordovician (Ov) age.      
	       Chert and greywacke also occur in Cariboo         
	       subterrane; marine
