Description
Stefano Pantaleone and co-authors ask if defective schreibersite can deliver phosphorus for early life chemistry, in a 2026 paper. Where the phosphorus used by life came from is a major open question. One leading idea sends it to early Earth in meteorites as an iron nickel phosphide mineral during a heavy bombardment about four billion years ago.
Water corrosion of that mineral is known to release usable phosphorus forms. Past simulations used a perfect crystal surface. The new work adds surface defects and finds the energy balance of corrosion shifts a lot, while the speed barriers barely move. The perfect surface thus stays a sound model for studying phosphate formation and later steps.
