Anthro, to Minerals

Intruded, glued and screwed
Pasted, thrusted and stacked
Eroded, weathered and packed

Ultramafic rock (peridotite) from an ophiolite sequence obducted and placed on the leading edge at the northernmost extreme of the Klamath Mountains. Weathered, consolidated and depleted/leached for 100+ million years to form residual saprolitic laterites rich in nickel and other more exotic metals.

A crucial source of nickel during WW2, Nickel Mountain above the town of Riddle, Oregon has been mined for nearly a hundred years…with tailings (dump rock) becoming bin rock in the operation’s latter days.

The characteristic light green garnierite (waxy/soap texture) is a wild combo of shearing/alteration/residual enrichment of the former ultramafic rock.

Casibari sits at the heart of Aruba and is a popular tourist attraction. And, yes, the cacti are native plants to the island which is arid receiving very little rain fall annually.

Man, this piece in @sciencemagazine by @voooos makes me want to go back to my geology roots.
What an exciting piece of new research

Exciting #geology news: at long last, ocean drillers exhume a bounty of #rocks from Earth’s #mantle.

Some definite mood whiplash in this article from @voooos - the excitement at getting a long borehole through mantle rocks, but the sadness that the achievement of this long-held goal comes as the Joides Resolution drilling ship is on the verge of being retired. https://www.science.org/content/article/long-last-ocean-drillers-exhume-bounty-rocks-earth-s-mantle

My toddler found (threw) this #Fossil in our rock wall. Is this actually a fossil, or is geology fooling this biologist?

This amazing view from a summit in the White , was my reward last week after 9 miles up through mud, , , and , plus multiple crossings of . Featured are the -covered slabs of rock in the foreground and the snow-capped peak of Mt Washington at the horizon. I enjoyed my lunch here before descending.

Black dendrites in chert. Dendrites are caused by hydrous iron or manganese permeating tiny cracks in the rock. #rocks #geology

So it took 3 hrs walking to get my electrical and iron garbage to the 'garbage point' (afvalpunt), because people without cars or bikes don't seem to exist.

BUT i could take some phototooototots! (sorry to tired to type and think or first think and then type).
The afvalpunt is very far, at the Toetsenbordweg (Keyboardroad, yes). Fun part of the names in this district: 'weg' means road but also 'gone' So: Keyboard gone. So now we know why they put the afvalpunt there.

It is a large industrial area near the harbors of Amsterdam, with huge buildings of all sorts, i like to wander there, although you always must be aware of all the trucks and vans that don't expect people there.

#Amsterdam #AmsterdamNoord #architecture #photography #industry

HannahCelsius,

There is art as well in this area. This work of 2 rocks is by Ton Kalle, it's called 'So What' and yes, it certainly seems to radiate that.
It is situated in the Backupstraat.

😂

Much better photos of the artwork are here, with (Dutch) information and a link to the site of the artist:

Sneaky peek at what is coming... :blobcataww:

It is a Fediverse movie bot, but not a Mastodon bot... it is a specialized ActivityPub server. :fediverse:

rafaelcaricio,

@retiolus Yeah, I need to make it not boost replies 😆 I just took a note on that, it is annoying indeed.

The rating system that I thought of was based on hashtags. Just add a tag to a post and the highest rated tag will be the "vote" for the rating.

1 - #meh
2 - #ok
3 - #cool
4 - #great
5 - #rocks

It would be configurable for every instance of FediMovies, by their admins, what are and what it means each hashtag.
