Story summary
- The Geological Society of America Bulletin reports that ancient salt diapirs formed in southern Australia about 640 million years ago and shaped early ecosystems by providing refuges during harsh global conditions.
- These salt structures helped life persist through mass extinctions and contributed to simpler carbonate reefs mainly composed of stromatolites.
- These formations aid modern resource management, including hydrogen storage projects.
