Lithology and environment
| Primary lithology: | lithified mudstone | ||
| Environment: | delta plain | Tectonic setting: | rift |
| Geology comments: Fossils presumably from mudstones, which represent overbank deposition, shallow lakes, or interdistributary bays.
As a result of the opening of the Labrador Sea in Late Mesozoic to Early Cenozoic times, a complex of linked rift basins stretching from the Labrador Sea to northern Baffin Bay developed along West Greenland. Two main episodes of regional rifting and basin development during this time have been documented in the area: an episode of Early Cretaceous rifting, and a Late Cretaceous – Early Paleocene rift episode prior to the start of sea-floor spreading in mid-Paleocene time. | |||
