Summary:
Name Barriefield Hill Metabentonite is proposed for a mixed-layer clay characterized by "giant" euhedra of bipyramidal quartz at Kingston, Ontario. Bed occurs in the lower part of the Blackriveran Lowville Formation, approximately 28 ft below the Little Cataraqui Bed (new name) and 12 to 14 ft above the Pamelia-Lowville boundary. Unit is 0.75 ft thick in measured section at Depauville, NY. May correlate with the Boonesborough Metabentonite No. 1 of KY, which also bears bipyramidal quartz euhedra.
