Quaternary stratigraphic units have been mapped in the Appalachian region of southeastern Quebec, and formal stratigraphic names for these units are proposed. Evidence exists for four separate glacial phases, the last three of which are represented by tills. The three tills, from oldest to youngest, have been named Johnville, Chaudiere, and Lennoxville, respectively. Stratified sediments interb...

The Late Triassic age Blomidon Formation consists nearly entirely of massive gypsiferous mudstone and sandstones arranged into distinctive sand patch cycles, many of which show various salt dissolution features. Identical Late Triassic, cyclical, largely clastic facies are widespread in Morocco, on the conjugate margin to Nova Scotia, where Blomidon-like strata frequently pass in the subsurface...

this study shows that ichonology can be used to refine sequence stratigraphy as well as to interpret the depositional environment of the kalat formation (upper maastrichtian) in the central kopeh- dagh basin (ne iran), dareh-gaz section. field studies and petrography of these deposits led to recognize four lithofacies and nine subfacies that formed in the tidal flat (lithofacies a), lagoon (lit...

the nw-se trending zagros fold and thrust belt extends for about 1,800 km from a location some 300 km se of the east anatolian fault in ne turkey to the strait of hormuz where the north-south trending zendan-minab-palami fault system (zmp) separates the zagros belt from the makran accretionary prism. the ne limit of the zagros belt is marked by the main zagros reverse fault which is rotated abo...

western and eastern populations of goitered gazelles are separated by zagors mountains as a barrier. bordering iraq, western population has suffered from drastic decline during and after iran-iraq war. presently, there are small numbers of the goitered gazelles left in the region with no clear understanding of their taxonomic status. it has been normally assumed that there should be a differenc...
