Lithology description: The Kalkberg is composed of thin- to medium -bedded limestones which have moderately irregular bedding planes. It is usually dark blue, finer grained than the Coeymans or Deansboro below and is very siliceous. It weathers light to dark gray and a rusty or yellowish argillaceous coating often forms on the weathered surface. By far the most characteristic eatures of the Kalkberg are the presence of black chert and the common coccurrence of calcareous and argillaceous shales interbedded with the limestones, both of which are lacking in the Coeymans. . . . it is quite fossiliferous
Environment:carbonate indet.
