Constraints on Moon's Orbit 3.2 Billion Years Ago From Tidal Bundle Data
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 ... -
In situ S‐isotope compositions of sulfate and sulfide from the 3.2 Ga Moodies Group, South Africa: A record of oxidative sulfur cycling
Nabhan, Sami; Marin‐Carbonne, Johanna; Mason, Paul R.D.; Heubeck, Christoph (Geobiology, 2020-04-16)Sulfate minerals are rare in the Archean rock record and largely restricted to the occurrence of barite (BaSO4). The origin of this barite remains controversially debated. The mass‐independent fractionation of sulfur ... -
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) ... -
The Malolotsha Klippe: Large‐Scale Subhorizontal Tectonics Along the Southern Margin of the Archean Barberton Greenstone Belt, Eswatini
Heubeck, Christoph; Thomsen, Tonny B.; Heredia, Benjamin D.; Zeh, Armin; Balling, Philipp (Tectonics, 2023-01-03)Whether Archean tectonics were horizontally or vertically dominated is controversially discussed because arguments bear on the kinematics and thermal state of the Archean mantle and constrain the mode of formation of the ...
