DENDRITES

Dendrites

At first sight I thought about a plant fossil, but looking up on internet, I come to the conclusion that:

This is most probably a crystal dendrite, which is a crystal that develops with a typical multi-branching tree-like form.
In paleontology, dendritic mineral crystal forms are often mistaken for fossils. These pseudofossils form as naturally occurring fissures in the rock are filled by percolating mineral solutions. They form when water rich in manganese and iron flows along fractures and bedding planes between layers of limestone and other rock types, depositing dendritic crystals as the solution flows through.(Wikipedia)

I could not find a adequate genre and category for this posting.
This is of course a documentary shot, but I thought that it was worth to show it.
The stone comes out of the quarry of Grenchen.

Hello Anne-Precise and Useful NOTE.Amazing creation of mother nature.Well captured.Although I don't know much about it.But I noticed such thing on old House Wall which was not dry.regards and thanks for sharing-Srikumar

Hi Anne,
This is Science in Nature. You correctly pointed out that these are dendrites. It is also my research topic. You can see here:

Hi Anne!
An interesting post of these Dendrites formed on the surface of a Sandstone. Very good sharpness and details.Darker color is because of oxides of Manganese or Iron. The rock in your shot is relatively fresh in geologic sense. In older rocks that has undergone erosion and give a somewhat polished look , these patterns can be extremely beautiful and give a real fossilized look (on polished sandstones and limestones). Rocks with very smaller dendritic patterns are cut and later transformed into beautiful earrings, rings and pendants. My wife does have a small collection of these. Thanks for sharing this fine presentation,
Best Regards,

hallo Anne
very good document to place on TN
beautiful colours and nice details
thanks gr lou

Anne,
I think this is a FIRST for TN.
These are, indeed, dendrites.
I've seen these in Goa, India.
A lovely presentation.
Great notes too.
Fond and warm regards,
Mario

Bonjour Anne,

Voila une composition bien scientifique , j'ai du moi même le terme sur internet.
Dont les principaux sont ceux de glace bien entendu, ici j'aime bien la texture.
Ici , il fait mauvias , je dois aussi rechercher les ancienne composition.
Bonne journée a toi.
Amitié de Belgique.

Hello Anne,
Like you, at first glance I thought this was a fossil of some fern plant. This is something new to me and quite educational. Isn't it interesting how it fans out similar to the way ice crystals do on a window, creating a picturesque image. I wonder if the red markings on the upper left hand corner are the same thing? Well done!!

Hello Anne,
Very well taken with its fine details of patterns and texture.
Best regards.....Joy

Hi Anne,
Very interesting and most probably never before seen subject on TN. Extraordinary shot and educative, very important note. Thank you very much for teaching us.
Best regards, László

Hi Anna,
Interesting image,nice structure nice colors and details.
Regards Jiri.

Hello Anne, A good example of dendrites and congratulations with a first on TN. Dendrites are often found in our area where they form on parting surfaces of along bedding planes in sandstone. Someone once told me that he had found a fossil of a fern and produced a specimen that he had taken. About three months later he told me the same again and added "I cannot remember who it was that said it was not a fossil but that is stupid. Anyone can see that it is a fossil of a plant." So they can be very convincing :) Best wishes.

Bonjour Anne

C'est un oeuvre d'art de la Nature,
et le contraste entre les tons de
couleurs est très jolie, TFS
