Unreasonable assertion

" The related East Greenland Rift Basin oil deposits are estimated to be one of the largest in the world.[1]"

There seems to be no tangible evidence for this "guess". No systematic exploration has been done. Lathamibird (talk) 07:59, 14 November 2015 (UTC)[reply]

Indeed, the cited source is only talking about offshore northeast Greenland, which is almost wholly unrelated to the topic of this article. Mikenorton (talk) 16:47, 11 September 2019 (UTC)[reply]

Age of the orogen

The article currently states that the orogen spans from Cryogenian to Late Devonian. The Eleonore Bay Supergroup and the overlying Tillite Group form a hugely thick passive margin sedimentary sequence deposited in East Greenland during the Cryogenian and Ediacaran. They are followed by a Cambrian to Middle Ordovician sequence. There is no orogeny interpreted during this time interval. The orogen is part of the Caledonian orogeny and is mainly Late Silurian in age. By the Middle Devonian the orogeny is over, with extensional tectonics taking over, with the formation of rift basins. I'm going to try to organise the sources necessary for a complete rewrite. Mikenorton (talk) 16:47, 11 September 2019 (UTC)[reply]
