An interesting inclusion for sure Richard. I wonder if the sulphide and the additional layer(s) of barite crystallised formed at the same time, crystalising out from either a fluid or a gaseous phase.
Richard, you know about Niels Stenson, who figured if animals and plants grow by fluid supply, why not xls? ( tho a trivial difference is they are nonliving, lol)
I just read that tonight thanks to Steve Sorrell's presenting, a few weeks back, a list of minerals books available online.
But just today with a gentle breeze and gentler incoming tide, I noticed that the broken sea grass blades weren't scattered everywhere like usually. They were lining up in amazing order, end to end, barely at the surface o the water, rows about 2 feet apart, extending many feet, tho I didnt measure. In the deeper water there were 2 lines of trees up ahead; maybe the very small waves were influenced by the tree rows to affect the broken leaves with their specific gravity being so precise?
Whatever, it was COOL, and reminded me of your bar(y,i)te phenomenon.
I wished I had my camera, but was swimming, and the shore was far away. The gradient for depth there is almost nil. You walk a long way to be just knee deep. I'll go back. Its a mere 2 miles away.
Cool observations, thanks. I guess for me the idea of crystallographic order is straightforward, molecular things finding their best way to pack together. These pencils of separate crystals (presumably) in such order are a lot more difficult to visualize forming, but maybe indeed something like fortuitous waves, in a particular situation, and the tide organizing your sea glass.

And thanks for adding the link!
That would certainly be interesting. I don't think I know enough to even speculate wisely.
