Spiniform stalagmite crystal
It will only be a rare occurrence on the living planet that once existed widely in the ocean with a depth of 100,000 meters. After the marine life on these planets die, and the corpse sinks to the bottom of the sea, it can directly mineralize with seawater under the deep sea high pressure. If there is a stable, smooth, slow, and hot ocean current at this time, spiniform stalagmite crystal may form under the blow of the ocean current.
