New names for Ordovician formations in Greenland

The names Cass Fjord Formation and Cape Weber Formation are restricted to strata in the vicinity of the type area of western North Greenland (and adjacent Ellesmere Island) and East Greenland, respectively. The so-called Cass Fjord Formation of East Greenland is renamed the Antiklinalbugt Formation, while the Cape Weber Formation of Washington Land, eastern North Greenland, is renamed the Canyon Elv Formation.
