Figure F3. Representative sequence boundaries from the Bethany Beach borehole. Sequence boundary (SB) within the Calvert Formation (1057.95 ft; 322.46 m) separates dolomite cemented silty very fine sand above (lower shoreface) from silty clay (offshore) below. Sequence boundary within the Calvert Formation (897.7 ft; 273.62 m) separates fine silty sand (distal lower shoreface) above which has been burrowed down into medium sand (upper shoreface) below. Sequence boundary within the Choptank Formation (787.1 ft; 239.88 m) separates shelly sand (distal upper shoreface) above from medium sand (proximal upper shoreface) below. Sequence boundary within the unnamed glauconitic clays and clayey glauconite sands (1430.5 ft; 436.02 m) separates clayey glauconite sand above from silty clay below.
