Constraints on Moon's Orbit 3.2 Billion Years Ago From Tidal Bundle Data

Eulenfeld, Tom; Heubeck, Christoph (Journal of Geophysical Research: Planets, 2023-01-04)

The angular momentum of the Earth‐Moon system was initially dominated by Earth's rotation with a short solar day of around 5 hr duration. Since then, Earth gradually transferred angular momentum through tidal friction to ...
Reassessing evidence of Moon–Earth dynamics from tidal bundles at 3.2 Ga (Moodies Group, Barberton Greenstone Belt, South Africa)

Heubeck, Christoph; Bläsing, Saskia; Drabon, Nadja; Eulenfeld, Tom; Grund, Marc Ulrich; Homann, Martin; Janse Van Rensburg, Deon; Köhler, Inga; Nabhan, Sami; Rabethge, Carolin; Voigt, Thomas; Zentner‐Joerges, Danielle (Sedimentology, 2022-04-05)

Past orbital parameters of the Moon are difficult to reconstruct from geological records because relevant data sets of tidal strata are scarce or incomplete. The sole Archean data point is from the Moodies Group (ca 3.22 Ga) ...
