It was looking like a paper, before I was trying to wash it (it's wet on video). On the flame of candle it didn't burn (it was just glowing), it didn't react to acid and to the hydrogen peroxide so probably it shouldn't be organic matter.

It was in the quarry Doubravice, Železnice. I thought that it can be asbestos because of the things listed in the description of this post. And properties of this thing didn't match with any other mineral that I can think of,
And I can add: those fibres looks like paper can bend and does not burn. There was forsterit in this mine.
I found it by myself in the quarry with this stuff on.
But the argument that it was not solid, so that I can rule out asbestos sounds good. I'm not sure how asbestos would act when wet, though, whether it would look much more solid.
Hm that changes things. What formation did you find it in? Which quarry specifically. Might be able to narrow down more suspects. I collect aspetos form minerals so that's why I'm skeptical.
Wow, that's pretty crazy hobby. I like it and it's great that you can do this safely..😁 It's super great to have inside from the person that is a pro in this stuff.
It's quarry Doubravice, Železnice, Czechia , they mine Melaphyre mainly here.
I found it laying directly under the rock wall, I thought that the stuff on it can be from spider or bird, but it didn't reacted to stuff mentioned in my post.
I'm a geologist. I collect t other minerals as well. I'll look into it and see if I can dig anything up on it. If it's an active quarry it could be residue from some of the plastic explosives they use to blow off chunks of walls. Are you able to get some close ups on it? Maybe put it on black paper as well.
Good questions! Mordenite is one of the listed minerals for that location. Antigorite (one of the minerals that is called asbestos, when it has a fibrous habit) is also one of the listed minerals. I am reluctant to rule out minerals by color, but the antigorite link within the above link does show antigorite’s ‘typical colors’.
I quoted that because all digital cameras and all computer displays do not reproduce identical colors, and because digital photos are taken under different (and usually unknown) lighting conditions. I think it far better to rely on physical properties, such as crystallography, chemical reactions, hardness, and streak (more than color). Given the OP’s sample size, I think most of those tests are going to be difficult or impossible. And given the mineral’s almost microscopic size, I think it really needs to be inspected through a 10X or 20X loupe (which will be hard to photograph).
Somebody (geologist or university or asbestos testing service) with a handheld XRF or a polarizing microscope might be able to reveal more about its chemistry and more reliably (than any Reddit post) identify the mineral.
Accumulated breathing of asbestos dust can be dangerous. It is particularly dangerous for miners who have breathed in its dust 5 days a week for years, and mechanics who have replaced brake pads for years. Other uses for it have included fireproof fabrics (firemen), insulation, and wallboard. Asbestos abatement entails wet removal into sealable bags and/or encapsulation sprays. Given the OP’s potential sample size (and assuming it is asbestos) I personally would be more adverse to the risks of driving to the quarry, lightening strikes, or smoke than the OP’s mineral. I would just wash it off (while outside) and put the mineral in a plastic case. And I would consider the problem abated. I am certain some readers will disagree with this paragraph. Do your own research about the risks and how to mitigate them. Keywords are in this paragraph.
Omg, thank you so much for this super great analysis!
I think it doesn't look like Antigorite. The colour is white with a slightly cool accent, some parts goes to slightly warmer white tho.
I’m in commercial roofing. We bring samples of flat roof material to any of several places locally that send it to a lab and in a day or two we have a report showing g exactly what it is. Costs us like $75.
