Lithology and Thickness
Green and grayish-green, generally finely sandy clays, and, green to gray calcareous sandstones. The latter commonly weathers to fine concretionary pellets. Minor amounts of cream to gray marl and one bed of gypsum are also present. Much chert occurs at a number of levels. The basal 5-10 meters is commonly cream sandy limestone.
Lithology Pattern:
Sandy limestone
