New approaches to the Moon's isotopic crisis
Abstract
Recent comparisons of the isotopic compositions of the Earth and the Moon show that, unlike nearly every other body known in the Solar System, our satellite's isotopic ratios are nearly identical to the Earth's for nearly every isotopic system. The Moon's chemical make-up, however, differs from the Earth's in its low volatile content and perhaps in the elevated abundance of oxidized iron. This surprising situation is not readily explained by current impact models of the Moon's origin and offers a major clue to the Moon's formation, if we only could understand it properly. Current ideas to explain this similarity range from assuming an impactor with the same isotopic composition as the Earth to postulating a pure ice impactor that completely vaporized upon impact. Several recent proposals follow from the suggestion that the Earth–Moon system may have lost a great deal of angular momentum during early resonant interactions. The isotopic constraint may be the most stringent test yet for theories of the Moon's origin.

“The circumstances required for some of these events may also have low likelihoods; however, with only one Moon to study, we are reminded that its origin could be improbable (Melosh 2014).”

“This is a concern because the Moon has a near-identical isotopic composition to Earth for many elements (Meier et al. 2014;Melosh 2014;Lock et al. 2020)”

“Subsequent numerical simulations by Canup & Asphaug [26] strongly supported the giant impact scenario and demonstrated a wide class of conditions under which a planetary-scale impact could produce a large moon with the angular momentum of our current Earth–Moon system.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
