Lithology and Thickness
Collingham Fm:
LITHOLOGY = Has been interpreted as passive suspension settling of mud intermixed with distal turbidites, periodically interrupted by volcanic ash fallout. (deep marine). thin beds of siliceous, dark grey mudstone alternated with softer, yellow-grey tuff beds.
CALIBRATION = 50% in interval.
