Abstract: | Upper Cretaceous nodular limestones in Jordan were originated by burrowing organisms of the types Thalassinoides, Callianassa or Ophiomorpha. Although burrows are difficult to recognize in the pure lutitic limestones of northern Jordan, in the south they are filled by early diagenetic stochiometric dolomite or chert. One may conclude that some nodular limestones hitherto described, are products of burrowing organisms and not of purely chemical processes. |
