L'Arctica era un antico continente formatosi pressappoco due miliardi e mezzo di anni fa, nel Neoarcheano.
Era formato da cratoni dell'Archeano, tra cui i cratoni Slave, Wyoming, Superior, dallo scudo canadese, dai cratoni Aldano, Anabar e Angara[1] dello scudo siberiano ed era situato nell'attuale Oceano Artico, in prossimità del Polo Nord.
Circa un miliardo di anni fa, l'Arctica si unì alla Nena ed all'Atlantica a formare il supercontinente della Rodinia.
Denominazione
La denominazione Arctica fu data da Rogers nel 1996,[2] perché il mar Glaciale Artico si formò in seguito alla separazione del cratone nord-americano e del cratone siberiano.[3] I geologi russi lo avevano indicato come Arctida nel 1987 o Cratone Iperboreano[4] in riferimento alla mitica Iperborea dell'antica mitologia greca.
Il russo Nikolay Shatsky [5] nel 1935 fu il primo a proporre che la crosta della regione artica avesse un'origine continentale.[6] Shatsky tuttavia erroneamente ritenne che la presenza di rocce metamorfiche precambriane e paleozoiche nelle Isole De Long, Wrangel e Nuova Siberia fosse dovuta alla subduzione. Altri studiosi proposero che il Nord America si fosse staccato dall'Eurasia e che il bacino Artico si fosse aperto in seguito ad una retrazione dell'Alaska.[7]
