The December issue of the GA Magazine is out now!

The current issue includes excursions to Canada and Iceland and a UK field trip to Derbyshire. Plus articles on the historic fossil collection of the first GA president: Joshua Toulmin Smit and geological aspects of nuclear waste disposal.

For this far violet line could be nothing else than the terrible mountains of the forbidden land--highest of earth's peaks and focus of earth's evil; harborers of nameless horrors and Archæan secrets; shunned and prayed to by those who feared to carve their meaning; untrodden by any living thing […]

Wow, those are old! 'Formed 2.2 to 2.8 billion years ago, during the Archaean Eon, when early life (cyanobacteria) produced oxygen, causing iron to precipitate out of the water."

I feel like people that throw the word Archaean around are full of shit and just try to sound mystical or some such thing.

The newly discovered archaean 𝘚𝘶𝘬𝘶𝘯𝘢𝘢𝘳𝘤𝘩𝘢𝘦𝘶𝘮 𝘮𝘪𝘳𝘢𝘣𝘪𝘭𝘦 has a genome with 238,000 base pairs, far fewer than humans (billions) or 𝘌. 𝘤𝘰𝘭𝘪 (millions). The species was named after Sukuna-biko-na, a Shinto deity known for being tiny.

The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by genome sequencing.

Well, let's give bacteria it's due: a lot of bacteria is life sustaining for us.

And, you know, we wouldn't be without bacteria - the Archaean atmosphere wouldn't support aerobic life, and bacteria drove mass photosynthesis.

Viruses too... gotta know your friends 🙂. Less harmful than Trumps.

It's not like eukaryotes and Archaea, where we've moved on to fine details of which Archaean clade eukaryotes are a member of, because the research so far has been converging

Close-ups of the individual panels/floors.

Each level reads from bottom to top, left to right, and represents a different stage of Earth history. Can't remember why I never colored them (either I didn't want to after coloring the background or just ran out of time.)

Perpetual motion is really OK as long as you don't use it to do any work. In fact, the Earth's rotation isn't really perpetual. It's continually doing work owing to tidal stresses and is slowing down. Back in the Archaean, the length of day was probably around 16 hours.

The Wongan Hills area has a fantastically rich plant diversity, and a lot of that is down to the harsh climate combined with complex geology - Archaean rocks of the Yilgarn Craton -

His preliminary sledging and boring journey of January 11th to 18th with Pabodie and five others--marred by the loss of two dogs in an upset when crossing one of the great pressure ridges in the ice--had brought up more and more of the Archæan slate; and even I was interested by the singular […]

stellarism is the religion of archaeans. archaeavids both adopted and influenced the archaean pantheon too. iirc in the context of the story mona recalls their weddings are more fun than nazarene ones. archaeans basically view it as pageantry and culture first and just kinda have fun and fuck around

Mineral Monday: Battle between the Bands

The presence of low-Al komatiite-like rocks in the early oceanic crust were the reason for both the formation of BIFs and their abundance in the Archaean/early Proterozoic era.

Though few or none of their first cities seem to have remained beyond the Archæan Age, there was no interruption in their civilization or in the transmission of their records.

UNTITLED ZEPHYR SUPPLEMENT

This one is slow-cooking in the background and getting filled with more and more ideas as time goes by. It's my to-go relax project TBH - I find working on supplements and add-ons as a great break from mainline releases like Nibiru and the Salt States.

It was built for an earlier archaean epoch of the series of tubes that is the World Wide Web, where the most consequential discussion happening was between nerds at CalTech & MIT bickering over whether James Kirk could really defeat a Gorn in hand-to-hand combat... not for our present, fallen age.

Archaean #Baryte deposits of the Barberton Greenstone Belt provide insight on the composition of Earth’s atmosphere and crust 3.2 bya. Sulfate-bearing meteoric water combined with cold spring-sourced Ba formed Baryte deposits in sands and cherts. Fluor- and phosphorescent.

most of the western europeans are elves due to the enduring victory of the glorious archaean republic of vitalis and its dinosaur friends. so just the sharp ears, terrible attitude, and fun hair colors if you're german, brittish, french etc

Nah bacteria can’t survive 60C. Must be archaean of you.
