Strange combination of #volcanic #rocks along the #Allier river (France). #olivine bearing #basalt (~1.8Ma) and large #plagioclase #crystals in #granites from the much older basement. Could never be formed contemporary.

MAGIC CLIMATE BULLET
wishful thinking? what if I told you that testing is under way for a solution that will roll back CO2. it is a one-shot global deal, so we have to be ready with system change or it’ll all come back.

Olivine weathering - Works in Progress https://worksinprogress.co/issue/olivine-weathering

The author is not a climate scientist. Nevertheless, he has put a lot of work into this article. I'd be most interested in seeing what qualified geologists' and climate scientists' responses would be.

If this works, it would not only reduce atmospheric CO2, but as it does so (it is claimed) via CO2 in the sea, it would reduce sea acidity which has an adverse effect on coral and diatoms.

And then, after one final reminder that the city will officially be worshipping fossil fuel next week, I got back home, with a loaf of bread for my lunch picked up in the city centre and a 20 kg sack of olivine ("greensand") which will eventually absorb about 20 kg of CO2 when I use it in the garden. I don't use any fossil fuels, but others unfortunately still do.

"I had to kill him. You have no idea. You never did. No idea how close we were to the poorhouse. I saved us!"
I looked at the "emeralds" she had wrapped in her skirt.
"#Olivine," I said. "How fitting: a beautiful but ultimately common stone prized by fools."
Still I loved her.

I am sure #ElonMusk's face turned #olivine during the "rapid unscheduled disassembly". I could be wrong though. #vss365 #Prompt #SpaceX

Once, he had seen a sky before a thunderstorm. White #cumulus was driven away by grey clouds darkening a golden sun until the sky was overcast in #olivine.

It #express-ed how he felt, as the shame moved in upon his open heart.

If he only knew.

#Olivine green walls
Muted
Soft
Minds eased, as bodies ache
'Neath a buzzing strip light glare

Angels scurry
Too busy
Too stressed
Through bleach haunted wards
To answer the calls born of need

And in my crisp bed
I lower my head
And stare at the wall

Muted

Kasseh was busy in her workshop. Cecelia slipped off to the kitchen & boiled water for tea. She had a new tea that was supposed to make you drowsy. She carried two cups into the workshop. Kasseh looked up.
"What are you doing up, Cece?"
"I couldn't sleep," Cecelia said. Then, glancing over at Kasseh's work, she said, "Oh, my! Are those emeralds?"
"Pretty, aren't they?" Kasseh said, accepting a cup of tea. "But they're actually peridot. They're made from a mineral called #olivine."

This is a panoramic #picture of "El Golfo" on #Lanzarote, taken with my #nikon #D60 some years ago. In the black gravel you can find some tiny little #olivine #gems, I could spend all day there but alas, my skin.
My D60 was a quite cheap #camera but not too bad at all. As somebody said: "Don't worry, it's a Nikon".

This morning's exercise ride was a 34 km round trip to collect another 20 kg sack of greensand. We've been using it with our potplants, mixed with compost from the garden to start tomatoes, and here in the front garden it's levelled up the ground above our potatoes.
Over time, each sack removes 20 kg of CO2 from the atmosphere and the process is beneficial to growing plants. Three sacks make a very small difference to our historical emissions, but if I'm going to buy soil of some kind for the garden it may as well be this. I certainly won't buy #peat which would help to destroy an ecosystem somewhere and release CO2 into the atmosphere.

Photos of this morning's recreational ride. It took an hour and ten minutes to ride 37 km, my average speed being pulled down by riding slowly into a farmyard at around the half way point to buy another 20 kg sack of olivine.
We've been using this sand-like ground up olivine in pot plants indoors and also in the garden to fill gaps.
Plants seem to grow well in it.
Olivine is one of several minerals which absorb CO2 from the air as they weather so my feeling is that if I'm going to spend money on something to put in the garden or use for planting indoors, why not use olivine which has a small positive effect on the climate?

#DidYouKnow: #Olivine is one of the primary components of the Earth's upper mantle, it is a common mineral in Earth's subsurface, but weathers quickly on the surface.

For this reason, Olivine has been proposed as a good candidate for accelerated weathering to sequester carbon dioxide from the Earth's oceans and atmosphere, as part of climate change mitigation.

@FransVeldman @henkdeligt @haayman Meestal waar, maar er zijn manieren om CO2 op te nemen die permanent zijn zonder kost van teveel energie. Bijvoorbeeld weathering van minerals.
Olivijn is een van de meest voorkomende minerals op aarde en vormt een groot deel van de aardkorst. Normaalijk reageert het langzaam met water en CO2 uit de lucht, waarbij het koolstof opslaat op een manier die veel energie kost om het vrij te maken. Als we het mineraal mijnen en vermalen, gaat dit proces veel sneller.
Het lijkt mogelijk om olivijn te mijnen en te vermalen op een manier waarbij minder CO2 vrijkomt dan het mineraal kan opnemen.
In Nederland is Olivine verkocht onder de naam greensand. Ik heb er een beetje van in mijn tuin.
Dit is natuurlijk geen oplossing voor eindeloze gebruik van fossiele brandstoffen - daar moeten een einde aan komen.

#introduction post wahoo
I really like #megaten especially for the #mythology aspect; I love learning about demons and their origins. I'm currently playing #megamitensei2 , though at an incredibly slow pace since I kind of know what happens next at the Tokyo Tower. The music in this series is incredibly good even from its NES days!
Other things I'm into are #NUcarnival (#Olivine my beloved) and #fireemblem (particularly #fe4, with extra love for the substitutes :blobblush: )
That's it, I think.

Take a look into this study on #Olivine weathering in field trials to store CO2: ‘6 to 8.5 percent of the initial mineral dose was dissolved after two years’; no chronic toxic risks of nickel release https://deltares-deltares-p01-website.s3.eu-central-1.amazonaws.com/app/uploads/2022/12/11204378-000-BGS-0002-Olivine-weathering-in-field-trials-DEF.pdf
