I'm working in an office in Slough industrial estate watching a gull collect sticks for a nest.
I guess windowless data centres are just another form of cliff, their tops safe from predators.

Also holly bushes stop growing prickles above the browse line and this is at mammoth height, which is higher than deer height.
E.g nearer 2 meters than 1.
I read somewhere (I think via @jacquelyngill.bsky.social ?) the idea that Northern European forests are missing mammoths still. Before humans, they would have played the role of knocking down trees and creating clearings.

Yet presumably in life they were just as much a zipping tentacled dealer of death as ammonites. Super useful index fossils as well, just nobody puts them on lamp posts.

Similar to the other. A brown broken triangle shape is another fossil
Enjoying the frenzied limestone at Augsburg station, noisy with tropical life. Plenty of fossils and blotchy with bioturbation.
Each grain is the product of life and probably passed through the guts of, or been picked over by multiple critters subsequently

blueschist-facies metabasite from our study area with complex, refolded isoclinal folds, consisting of alternating epidote and glaucophane layers.
1/ Have you ever suspected you had a shear zone hidden in poly-deformed metamorphic rocks but could not prove it? A brief thread showing how you can find clues from #geology, RSCM #thermometry, #metamorphic #petrology, and #zircon dating and an example from the Sanbagawa belt of Japan!

Definitely go to the museum and buy the geo guidebooks. If you have transport go and see the suevite quarry at Altenburg, the overturned limestones at Gosheim Quarry and if you can get out to Steinheim crater, go there too 1/2

Apart from the visitors centre and the church made of suevite, any ideas on what should I look out for?

A single rock can give many different ages, to put it another way. What they mean is sometimes not so obvious....
07.02.2025 16:01 β π 2 π 0 π¬ 1 π 0It depends on what they are getting the isotope age from. It's usually individual minerals. If those minerals are completely melted and reform, then you get a new age. Sometimes though minerals in an igneous rock weren't melted and show an older age. They're called 'antecrysts' IIRC.

That's my experience also. I suspect there are a lot of bad training courses out there that people rightly take a dislike to.

You can't tell your employees to change who they are but you can get them to think about psychological differences.

Is there any research on the gold sourcing?
Any ideas on a species for this seed pod/nut?
Local or from further afield?
Found it washed up on the beach this morning.
County Clare, Ireland.
Folded metasandstones surrounded by schists (a type of metamorphic rock) with a pen for scale.
#GeologicalRelief for my American friends...
Some of the best folds I have seen in my life in schists and metasandstones... second phase folds refolding an earlier foliation parallel to bedding.
