| Urgonian facies are also characterized, negatively, by the absence of ammonites and belemnites. |
| Changes in Mesozoic and Cenozoic thicknesses and facies across the northsouth faults indicate their pre-collisional origins. |
| To achieve this goal we map the spatial distribution of volcanic seismic facies units. |
| Where cored the Auk Formation is easily identified because of the preservation of aeolian dune facies. |
| To accomplish these, however, a more thorough paleontological investigation of each taphonomic facies is necessary. |
| The bed thickness is variable from thinly bedded to massive beds up to 9 m thick, and the contacts with other facies are generally gradational. |
