gondwalaland: then now and forever

of course there had to be some middle aged looking Nu metal type band called Gondwana.

not too far away from that, is this 'Foetus does library music' project :

While probably not a supercontinent, one can argue that Ur was a supercontinent for its time.

xp

oh my, just came to paste the EXACT same thing here

the 'supercontinent for its time' thing

Definitely silly enough to post twice. Every geologic era gets the supercontinent it deserves.

the drifting microcontinent Avalonia is a curious thing, proto Eire/UK but with volcanoes and weather and still carrying parts of Canada and New York.

probably getting my timezones mixed up here and wondering if this thread is snubbing Laurasia?

the band Gondwanaland have been going since 1982, I’d expect Charlie McMahon is looking a bit older than middle-aged by now

omg this is a gorgeous paragraph:

Very thick sections of mostly submarine mafic, and subordinate ultramafic, volcanic rocks, and mostly younger subaerial and submarine felsic volcanic rocks and sediments were oppressed into complex synforms between rising young domiform felsic batholiths mobilized by hydrous partial melting in the lower crust. Upper-crust granite-and-greenstone terrains underwent moderate regional shortening, decoupled from the lower crust, during compositional inversion accompanying doming, but cratonization soon followed. Tonalitic basement is preserved beneath some greenstone sections but supracrustal rocks commonly give way downward to correlative or younger plutonic rocks... Mantle plumes probably did not yet exist, and developing continents were concentrated in cool regions. Hot-region upper mantle was partly molten, and voluminous magmas, mostly ultramafic, erupted through many ephemeral submarine vents and rifts focussed at the thinnest crust.... Surviving Archean crust is from regions of cooler, and more depleted, mantle, wherein greater stability permitted uncommonly thick volcanic accumulations from which voluminous partial-melt, low-density felsic rocks could be generated.

(from https://en.wikipedia.org/wiki/Craton )

Bliss was it in that dawn to be alive. But to be a rising young domiform felsic batholith was very heaven!

In tweezozoic eras, most of the supercontinent was uninhabitable, dry scorching rock. If the supercontinent happens to move over a pole, its snowball Earth, with nothing going on, biologically.

Whether Vaalbara, Ur, Kenorland, Columbia, Rodinia, Pannotia or Pangaea, interiors of supercontinents are lousy places for the inhabitants (only in the last 2, the first 5 had no macroscopic life). Hopefully Earth life will escape its planetary confines before Neopangaea/Pangaea Proxima some 250 my in the future. Beyond that, things look rather difficult for multicellular life as solar luminance continues its inexorable increase and the carbon cycle kills all autotrophs. Life has maybe one more supercontinent cycle after that. The deep sea reduced sulfur biomes and deep rock radiation eaters have another half billion years before the planet is sterilized.

meanwhile this is soothing:
