I can not find a similar image or info on the net to identify my presumably Cave stalagmite. I would like to know where and how it formed. Now the black interfiling i'm assuming to be water that fossilized somehow inside the after seeping through layers of rock until it got trapped in this reservoir of stalagmite, It is almost crystal structured meaning no pockets of air or any other substances so it must of been filtered through sand and coal to get the black color.
This is all thought theory based and I have no knowledge on stalagmite or how they formed thus being my first sample. Please correct me if I am wrong.
If my theory is correct on the black filling being water does anyone know how this process occurred and what is it composed of?
Also any information or photos that resemble this specimen would be of great help.
