On lunar asymmetries 1. Tilted convection and crustal asymmetry

It is proposed that lunar crustal asymmetries are the result of convective processes acting early in the Moon's history, during the magma‐ocean phase and after synchronous rotation was established. Buoyant anorthositic crystals were transported to the farside by a large‐scale circulation, called tilted convection, known to occur spontaneously in chaotic convective systems. The circulation was oriented toward the farside of the Moon by a small …
