Rocks from #China's #Moon mission suggest Luna history revision
18 researchers from the Chinese Academy of Sciences, assess #paleointensity – a measure of historical #magneticfield. #Basalt samples thought to be 2.8B years old. Analysis suggests Moon's magnetic field has increased in strength. Moon once possessed a strong "dynamo" – the term for forces that create celestial bodies' magnetic fields – but it weakened around 3.1B years ago and shut down around 1B years ago.

Samples obtained by #China's #Change6 #spacecraft show #moon's ancient #volcanism
Researchers said the soil brought back from the Chang'e-6 landing site contained fragments of volcanic rock - #basalt - dating to 4.2 billion years ago and to 2.8 billion years ago. This points to a long period of volcanic activity - at least 1.4 billion years - on the far side during the first half of the moon's history, when it was a more dynamic world than it is today.

Another sunny day in Mull 🤯 . After meeting 2 nice lots of geologists from Leicester + Innsbruck Universities at Ardalanish this morning, headed off for picnic lunch at the enigmatically-named Eilean an t-Santachaidh (island of covetousness/desire) which is not actually an island, but hard to reach by land. Note the two intrepid sheep taking advantage of low tide to nibble seaweed. Geo info in Alt text. #Mull #Granite #Basalt #Sheep

I went out to Frenchman Coulee in central Washington. The landscape is made up of eons of lava flows and then carved out by huge ice age floods. I think its pretty interesting and definitely want to go back and visit some of the other coulees in the area!

Three basalt fins in White Rock Canyon, New Mexico. The big central fin has great petroglyphs, and there's a good cave between the left and central fin — cool in the summer and very cold in winter. The fins themselves are columnar basalt from cooled lava flows. Photo from a few weeks ago.

The quest to turn #basalt dust into a viable #climate solution
The #volcanic rock is chock full of nutrients, captured as its crystal structure forms from cooling #magma, and makes soil less acidic similar to #limestone, which f#armers often use to improve their #soil.But basalt also comes with an important side benefit: It can naturally captures #carbon from the #atmosphere. Sprinkling rock dust on #farmland to soak up atmospheric carbon will be tested at large scale. arstechnica.com/science/2023/1
