Geology of Greenland

The Isua Greenstone Belt in the Isukasia area, southwest Greenland, is extraordinary in that it contains some of the oldest bedrock on the planet, approximately 3800 million years old.

Gold-quartz mineralization occurs along a shallowly-dipping fault believed to be a thrust fault in which the hanging wall consists of Paleoproterozoic amphibolite-facies metavolcanic rocks, and the footwall consists of variably altered and mineralized volcanic rocks (i.e., volcanogenic massive sulfides).

[3] A number of fossils were collected in Greenland, mostly on the east coast, from Paleozoic to Holocene, from which the Devonian Acanthostega and Ichthyostega are examples of international relevance.

[4][5] The Late Triassic of Jameson Land is particularly relevant due to the finding of early mammals, found in the expeditions of Farish Jenkins.

The Fleming Fjord Formation yielded a number of theropod and sauropod tracks,[6] temnospondyls, phytosaurs and stem turtles.
