Embrioanian
Embrioanian is a hypothetical geological period or epoch proposed by some researchers, primarily within theoretical discussions of planetary development and exoplanetology. The term "embrioanian" is derived from "embryo," suggesting a stage analogous to the early development of a celestial body. It is envisioned as a period characterized by significant geological activity, intense bombardment by asteroids and comets, and the formation of a nascent atmosphere and potentially early oceans on a terrestrial planet.
This theoretical stage would precede the Hadean Eon in Earth's history or similar early phases on other
The concept of the embrioanian is not universally accepted as a distinct geological time unit, and its
