Wordie Creek Formation, Jameson Land, East Greenland. (Triassic to of Greenland)

Where: Greenland (73.0° N, 23.0° W: paleocoordinates 30.0° N, 12.3° E)

• coordinate estimated from map

• basin-level geographic resolution

When: Wordie Creek Formation, Griesbachian to Griesbachian (252.2 - 251.3 Ma)

• The locality shows a transition from the upper Oksedal Member of the Schuchert Dal Formation into the base of the overlying Wordie Creek Formation.

Environment/lithology: marine

• The sediments of the Schuchert Dal Formation and the overlying Wordie Creek Formation were deposited in a narrow, elongate, fault controlled basin. A well oxygenated benthic environment.
• The earliest Triassic in particular was a time of active rifting and rapid subsidence that resulted in an exceedingly thick marine succession. Some 700 m of predominantly silicalstic sediment were deposited during this interval and comprise the Wordie Creek Formation.

•The Greenland P-Tr record is among the most expanded in the world.

•This area is far enough away from later igneous intrusions that it has suffered no thermal alternation, unlike other localities elsewere.
