Contact - Dashed where approximately located



    Sheared unconformity - Double-ended arrow on side with 
    younger rocks, no sense of movement implied

    between formations




    Thrust Fault - Sawteeth on upper plate. Dashed where 
    approximately located, dotted where concealed; queried

    approximately located, dotted where concealed; queried where
    uncertain
