A speculative theory emerging: what if heat created these ruts? When limestone is heated to ~1000°C it becomes quicklime, which reacts with water to create a shapable slurry that hardens later. The same calcium oxide chemistry was used in Roman concrete! Material would collapse rather than push up - explaining the missing raised rims. Heat sources could include plasma discharges, coronal mass ejections, or ball lightning. Theory suggests something unusual happened here.
Heat-induced limestone transformation may explain cart rut formation
Key facts
- Heat theory: limestone heated to ~1000°C becomes quicklime (emits CO2)
- Quicklime + water creates slurry that can be shaped then hardens through pozzolanic reaction
- Same chemistry used in Roman concrete
- Heat source could be: plasma discharges, coronal mass ejections, air bursts, or ball lightning
- Material would collapse rather than push up, explaining absence of raised rims
- Could explain why footprints absent - humans may not be heavy enough to make marks

Why heat is produce on adding water to quicklime?yayangminerals.com
When quicklime (calcium oxide) is added to water filled in a bucket, they react chemically to form slaked lime (calcium hydroxide) and produce heat energy.
[Solved] What type of reaction occurs when limestone gets converted itestbook.com
The correct answer is Decomposition. Key Points. Limestone (CaCO3) decomposes into quicklime (CaO) and carbon dioxide (CO2) when heated.
