Well I love the blues! Your lapis is positively glowing.
Maybe your first cab is shattuckite?

I think they misjudge our gravitational pull and hit a little hard. There never is any sign of burnt or scorched material, so it must be from landing... Now for the truth, as ice forms on the beach it tends to clump up. Wind and waves tend to cover the ice with sand. When the ice melts, it leaves those little landing rings. I wondered if ice was involved. A bit like a pingo or hydrolaccolith then. Presumably just seasonal?

My thoughts are that pyrite would commonly form in a reductive environment that would be needed for the preservation of woody debris. Silicification following to create pet wood would be likely to preserve that. Look closely to see if there is any evidence of cubic crystal structure.
I'd be very happy for you to prove me wrong. Gold? ... you never know. I wish you luck!

Another battery tech advance. But this one should be Goodenough? Never mind Goodenough, I think I'm going to change my name by deed poll to Damnedamazing. See if it doesn't turn my life around?!

Its all about the regional economy. Prior to fracking in America, energy costs were headed up. Now natural gas is so cheap that some producers are burning the excess. I think in the UK, energy costs are up by 8% this year. Therefore, it makes sense to make some (relatively cheap) provision to reduce those costs in the longer term. I don't have to go off-grid, but if the cost of solar is falling and the price of energy is going up, the break-even point just moved closer.

Labradorite was also used as ship ballast and dumped in many areas. Perhaps from Madagascar Dave ? Probably from Norway. There's a load off the East coast of England not far from Hull. Larvikite I believe it is called as a stone containing the labradorescence that 1dave describes. Likelihood is that it has been used as ballast since the Viking times.

This appears to be very dark (/black) flint typical of Norfolk area, East Anglia. Some more info on a previous post here after I 'discovered' it (only 2 to 4,000-odd years after the stone-age really valued this material. The guys making arrowheads here in the south US are impressed with the UK flint. Probably the highest quality natural knapping material on earth metalsmith. It is silicified the same way our coastal plain chert and coral is by dissolved diatoms. The Flint River in s Georgia USA is paved with a similar grade but it is called chert. Chert-flint, not sure what differentiates the two. They are both chalk coated as is our coral. The source of silica is thin porous easily dissolvable silica skeletons of fossil diatom bedrock. add chemicals and ph changes for perfect recipe to make chert. As per linked thread the black flint was viewed as the best thing in the world (its just that the known world was smaller). So much so that when the archaeologists turned up black flint from far-afield, they had to re-evaluate their model of communication and trading for the period. Previously they thought that wood/mud-huts were about as far as technology had evolved. Suddenly they find that Norfolk black flint stone equipment had really travelled so if there was travel then there must have been travellers, communication, trade and much wider interaction than previously postulated.

Hi and welcome back. 6 tumblers sounds a healthy number. Sorry to hear of your illness. I hope you get better with each day. Coming here has helped me no-end.

Amazing spectackulated solanum tuberosum
or 'spud' as we call it in this neck of the woods!
Welcome and thanks for the stroll.
So how do the alien sand shapes form: dewatering or something else?

Want to see who has the ugliest slab? Here is my offering. I have named it "Uglisite". This stuff is hard. Quartz wont scratch it. Note how the image is reminiscent of toxic waste gently flowing into a slow moving stream. The greens have a decidedly mucus appearance and the random streaks of nasty brown material highlight the orange vugs of rust that are incoherently banded through the slab. Truly this is the ugliest slab I have cut. Uglisite by Glen Ray, on Flickr I lost a stone and a half recently. Looked a bit like this! (sorry too much info) This brings back bad memories...

How do from Blighty. I'm up before the owl in the garden this morning. Nice to meet you!
Show and tell! What started your interest and did your hunting catch any killer stones?

Similar to this stuff maybe? super hard material. I think it's kinda pretty but it really taxed my saw.
Eh? That's lovely! Reminiscent of Polish Banded Flint

Nicely done. My name is Solar. I've studied it for decades. Power is way cheaper than buying panels and accessories. And if they let you guys build modern nukes the enviro power guys would be doomed. No new nukes for many years to come. If I was going to take my new found obsessive compulsive hobby off line, I would fabricate an 'S' rotor wind spinner and use it to spin my tumblers directly. Prior to the electrification of rural America, there were wind driven grain grinders, water pumps and such. Same idea. They're building new nukes in the UK right now. I say 'they'. They being the French and Chinese I believe; not thought to be a good deal for the UK, but should the decision makers have the best interest of UK citizens at heart?! It guarantees power for a good part of the future and reduces reliance on overseas; I believe a good part of our gas comes from Scandi countries and Russia. I know which one of those I trust most.

Yes. And one man's "right thing" is another man's evil. Your mansion is perfect example. You and i agree. But you know that others see dead trees and trees are good! The issue really is why do people think that their opinion is better than yours or mine? Dead trees proved to be a really bad thing on Easter island where all the trees were cut down to roll statues to their final resting places. Destroyed the ecology and they starved to death, all for a belief system. Couldn't see the trees for the wood?!
