TL;DR: In this paper, the SAMBA (S outh Am erica-Ba ltica) connection between Baltica and Amazonia is discussed using compilations of recent data and regional geological models, and a fit with northwest Amazonia attached to southwest Baltica produces a closely matching pattern of westward younging Proterozoic growth zones and is suggested to have existed from at least 1.8-1.3

TL;DR: In this article, a refined model of Rodinia is presented, with Baltica, Amazonia and West Africa attached to eastern Laurentia as in the SAMBA model, and East Antarctica, Australia and India to western Laurentia in a SWEAT configuration.

TL;DR: Svalbard is located in the north-west corner of the Barents Sea shelf and the Eurasian Plate, in a key area for interpreting Caledonian and older orogens in the Arctic region as mentioned in this paper.

TL;DR: U-Pb dating has been carried out on zircons from three Smaland-Varmland granitoids as mentioned in this paper, and the results suggest that the postorogenic granites of the SMaland Varmland belt are older than indicated by previous Rb-Sr age determinations, and that they were formed penecontemporaneous with the Svecokarelian granites further east.

TL;DR: In this article, the ages of two types of intrusions from Lapponiahalvoya, northwestern Nordaustlandet, have yielded ages of 939 ± 8 Ma (Kontaktberget granite) and 961 ± 17 Ma (Lappoinafjellet granite), confirming previous, less precise multi-grain, Pb Pb evidence of Grenvillian igneous activity.
