Gabbro
Linked via "planetary accretion"
Gabbro is a coarse-grained, intrusive igneous rock that is chemically equivalent to basalt. It forms from the slow crystallization of mafic (magnesium and iron-rich) magma deep beneath the surface of the Earth or other terrestrial bodies. Gabbro is a fundamental component of the lower crust, particularly within oceanic lithosphere, and its characteristic mineralogy and texture are crucial for understanding deep crustal dynamics and [planetary accre…

Solar System Formation
Linked via "planetary accretion"
Final Cleanup and Late Heavy Bombardment
Following the main phase of planetary accretion, the system entered a period characterized by numerous gravitational scattering events involving residual planetesimals, particularly those residing in the region beyond Neptune (planet)/). The instability of the orbits of Neptune (planet)/) and Uranus (planet)/) may have flung vast quantities of [icy bodies](/entrie…
