Supercontinent is a sludge/post-metal band that drags you along through their expansive tracks of massive but measured metal. This is some awesome stuff.TRAC Vaalbara was an Archean supercontinent consisting of the Kaapvaal Craton and the Pilbara Craton. E.S. Cheney derived the name from the last four letters of each craton's name. The two cratons consist of crust dating from 2.7 to 3.6 Gya, which would make Vaalbara Earth's earliest supercontinent There are two contrasting models for supercontinent evolution through geological time. The first model theorizes that at least two separate supercontinents existed comprising Vaalbara (from ~3636 to 2803 Ma) and Kenorland (from ~2720 to 2450 Ma ). The Neoarchean supercontinent consisted of Superia and Sclavia. Vaalbara is no perfect record, mind you, but once I relaxed and let it carry me I found myself enthralled.

Ur would eventually join up with the continents Nena and Atlantica about one billion years later to form the supercontinent Rodinia. The results of correlation between geological events in the period of 2.8‒2.0 Ga provide grounds to assume that the Sarmatia lithospheric megablock definable in the southern part of the East European Craton belonged to the ancient Vaalbara supercontinent consisting of the Pilbara and Kaapvaal cratons. Vaalbara, Kaapvaal Craton, Pilbara Craton, U-Pb geochronology, paleomagnetism, supercontinent, large igneous province, dyke swarm, sill province Original language English Vaalbara is a music studio album recording by SUPERCONTINENT (Experimental/Post Metal/Progressive Rock) released in 2008 on cd, lp / vinyl and/or cassette.

The beautiful little melodic metal guitar flourishes in "Earthrise", and that melodic groove riff which comes in about 2/3rds of the way through the track. Here we show that the present geochronological, structural and palaeomagnetic data support such a Vaalbara model at least as far back as 3.1 Ga, and possibly further back to 3.6 Ga. Vaalbara fragmented prior to 2.1 Ga, and possibly as early as 2.7 Ga, suggesting supercontinent stability of at least 400 Myr, consistent with Neoproterozoic and Phanerozoic analogues.

As the album title suggests, "Supercontinent" is a conceptual voyage through various stages of ancient Earth's continental drift phase, from the earliest known supercontinent ("Vaalbara") to the most recent one ("Pangaea").

Current and past members include: Matt Gauntlett - Guitar/Vocals… read more View full artist profile Vaalbara was a supercontinent, possibly the first in the history of the Earth. It arose in a world dominated by oceans and small volcanic Island chains, a punishing world of low oxygen, crushing pressure, and intense heat. But even in this hostile early world, life was beginning. Stromatolites, layered mounds of rock deposited by cyanobacteria, lined many of Earth's rocky coasts and were just beginning to create the oxygen-rich atmosphere we know today. There are two contrasting models for supercontinent evolution through geological time.

The first model theorizes that at least two separate supercontinents existed comprising Vaalbara (from ~3636 to 2803 Ma) and Kenorland (from ~2720 to 2450 Ma ).
