Plume-related granite-rhyolite magmatism

Литосфера, 2020
Plume-related magmatism is widespread and its existence is well-founded. Mostly, plume-related magmatism is represented by trap rocks, oceanic island basalts (OIB) and oceanic plateau basalts (OPB), although the composition of plume-related igneous ...

Tectono-magmatic evolution of the younger Gardar southern rift, South Greenland [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2013
The 1300–1140 Ma Gardar period in South Greenland involved continental rifting, sedimentation and alkaline magmatism. The latest magmatism was located along two parallel rift zones, Isortoq–Nunarsuit in the north and the Tuttutooq–Ilimmaasaq–Narsarsuaq ...
