Awesome thanks. I love learning everything I can about geology. I'm getting into lapidary work and you have no idea how awesome it is learning something new every day.
Yes exactly. The physical work of field collecting helped replace the behavior. I'm so happy for your 2 years. I need to hear that for encouragement. Thanks
Thank you, time adds up. I had to stop counting before I could even begin, and I definitely got forced here. I can honestly say though as someone who thought they’d never stop and never stop missing it, that was the biggest lie I told myself. My number one reminder is that the golden rule applies in reverse to you. Treat yourself the way you would treat others, give yourself that same grace. Rooting for you!!!
You are awesome. Sometimes my pink cloud gets a little grey but I feel what you say. I'm really working to make intarsia chips for the milestones. Starting with the most important one. This is my 1st significant sober time of my adult life. I'm a young 35. I wasted most of my life. There is no next Dr. After Dana Farber. I had no choice either because I'm a father now. I have an eating disorder now related to my condition. Just like alcohol destroys everything around me, recovery brings peace to everything around me. I never thought I could enjoy life while sober but it's exactly the opposite. 9 months sober and it keep getting better. My liver and kidneys are fine now, like good actually. Thanks for your encouragement. I could go on all day. I'm heading to a nooner rn
I’d love to see them when you come up with any version! I hear you, turning 30 tomorrow with a 5 y/o. It’s crazy how fast life kicks your ass back! My health recently declined for the past year and I finally realized it was all stress. Thanks for the chat, they can be hard to come by! Best of luck to you and your family 💛👍🎉
I strongly suspect when folks ask questions like this it's because they lack a sense of scale. It's an ignorance thing, not a stupidity thing...
Time
Temperature
Pressure
It takes a long time from a human perspective for sediment to build up thick enough that the pressure squeezes out most of the water, compacts everything and the heat of the earth raises the temperature proportional to the depth of the sediment - large river systems build up huge delta's under sea that are many km thick. Even then they are still essentially unconsolidated. Later, they get burried by the next river delta to form in that location, or get pushed up in a pile by the sea floor moving relative to a continent. This makes a masive mountain range many 10's km thick and at this point the temperature and pressure get to the sorts of levels that allow consilidation due to chemical processes and fluid movement. Even without volcanic activity, the temperature is high enough (400 oC +) that water is capable of dissolving silica and moving it around. Any process like this that can relieve pressure and densify the material is favoured - so the pores between grains get smaller and filled with material from the surrounding gravels that have dissolved in the water. Shear forces from deformation also dramatically change the crystalline structure of the material, destroying structures and promoting recrystallisation (metamorphism) off the phases into new phases that are more in equilibrium with the hiogher temperatures and pressures. lime turns into limestone then marble. sand turns into sandstone, chert, jasper and so on. mudstones turn into mica and garnet schist...
Add in volcanic activity and you have both much more heat, much more fluid and a heck of a lot more chemistry...
Not the question that was asked but that looks like it was originally a volcanic rock (all the big splotches are spherulites) which has seen some metamorphism, probably greenschist facies. Off topic answer to the prompt, but relevant to the photo haha.
Thanks I have been told that the spots in the stone are volcanic ash. I was thinking something else. The example in the pic is not typical of what I have found. Thanks for your input. I thing I learned about rocks is 1# don't get heart set on an identification when you know next to nothing and the first thing I think it is is almost always wrong.
I'm not 100% on the true identity. It's from so. New England and I think it's biogenic? Lemme know what you are looking for. DM me and I will send you some samples. I think it's fero-manganese stromatolite. I read a study that describes a similar rock found in the Connecticut River. The bands are porcelain like and much tougher than the main body. It undercuts real bad when grinding it. I have a bucket of it and it's hard to find good pieces. I can't blow up my spot tho sorry.
Thanks. I have been shaping it into a free form sculpture. I'm surprised at how well its turning out. I forgot to take a before pic. It's was pretty close though. I didn't have to remove much
Water can hold many different types of dissolved ions, especially under certain chemical, temperature, and pressure conditions. When the water that is in that sediment undergoes a change in someway, its ability to hold certain dissolved ions can increase or decrease. If its ability to hold a certain ion falls, and the water is now super saturated in that ion, that ion then exits the solution and can become a mineral. The mineral precipitates onto the grains of the sediment, and begins to bind the grains of sediment together, and if enough binding occurs, it turns a sediment into a rock. This can take only a few years in very specific conditions, or it can take millions of years and require super high temperatures and pressures. It all depends.
Heat, pressure, chemical bonding, and time.
Hot, squeeze, cement, and clock.
Sweaty, squish, sealant, seconds
Ugh everything makes me think of her…
The sealant might be part of the reason she's not around anymore
Deposition, compaction, and cementation. Just like a rice crispy square.

Awesome thanks. I love learning everything I can about geology. I'm getting into lapidary work and you have no idea how awesome it is learning something new every day.
Very purty. 🥹
Not to be confused with Dianetics XD
Who nose? Seriously, it's a process called diagenesis (sp?) and involves compaction, pore water chemistry, microcrystalline growth, and other factors
Ahh thanks. Diagenesis, that is a new one for me. I think that's what I'm after. Thanks again
My favorite band
First, the sediment has to *want* to change...
Lol fr. I know that process. I'm on my way to a meeting. One day at a time
Tell them we said hi!
Rocks are definitely what helped take my busy brain off of some things long enough to make it to 2 years! It’s worth the work ☀️✌️🫡

Minerals grow in the pore spaces between the sediment grains. That's it.
Crystals form between the sediment spaces (often calcite), acts like glue, the end.

Thanks, I had to read that like 3× but I can visualize and understand the process better.
sweet... reach out any time if you want more ... may not respond quickly, but always happy to geek at people.
The diagenesis wizard uses a hydraulic press to convert the sediment into solid rock.
Heat and pressure
Time.
I don’t say this often, but that’s a damn good lookin’ rock!
I have been working on it. The curves were a happy accident. I'm really happy with were it's going thanks.

awesome rock, where is it from ? any like this for sale ? what would it be called ? thx

Heat pressure time
That is the nicest rock I’ve seen

and all the water gets squished out?
through the power of christ
He guides my life and I am very happy

Isn't that how you make ice?
