Olivine-rich achondrites from Vesta and the missing mantle problem.
Vaci Z, Day JMD, Paquet M, Ziegler K, Yin QZ, Dey S, Miller A, Agee C, Bartoschewitz R, Pack A. Vaci Z, et al. Nat Commun. 2021 Sep 14;12(1):5443. doi: 10.1038/s41467-021-25808-9. Nat Commun. 2021. PMID: 34521838 Free PMC article.
Northwest Africa 12217, 12319, and 12562 are dunites and lherzolite cumulates that have siderophile element abundances consistent with origins on highly differentiated asteroidal bodies that experienced core formation, and with trace element and oxygen and chromium isotopic compo …

A consortium study of eight of these classifies Motopi Pan as a HED polymict breccia derived from howardite, cumulate and basaltic eucrite, and diogenite lithologies. Before impact, 2018 LA was a solid rock of ~156 cm diameter with high bulk density ~2.85 g/cm(3), a relati …

An ancient core dynamo in asteroid Vesta.
Fu RR, Weiss BP, Shuster DL, Gattacceca J, Grove TL, Suavet C, Lima EA, Li L, Kuan AT. Fu RR, et al. Science. 2012 Oct 12;338(6104):238-41. doi: 10.1126/science.1225648. Science. 2012. PMID: 23066077
However, it has been previously uncertain whether Vesta and similarly sized planetesimals formed advecting metallic cores and dynamo magnetic fields. Here we show that remanent magnetization in the eucrite meteorite Allan Hills A81001 formed during cooling on Vesta 3.69 bi …

Discovery of coesite and stishovite in eucrite.
Miyahara M, Ohtani E, Yamaguchi A, Ozawa S, Sakai T, Hirao N. Miyahara M, et al. Proc Natl Acad Sci U S A. 2014 Jul 29;111(30):10939-42. doi: 10.1073/pnas.1404247111. Epub 2014 Jul 15. Proc Natl Acad Sci U S A. 2014. PMID: 25028493 Free PMC article.
Howardite-eucrite-diogenite meteorites (HEDs) probably originated from the asteroid 4 Vesta. We investigated one eucrite, Bereba, to clarify a dynamic event that occurred on 4 Vesta using a shock-induced high-pressure polymorph. ...

Dawn at Vesta: testing the protoplanetary paradigm.
Russell CT, Raymond CA, Coradini A, McSween HY, Zuber MT, Nathues A, De Sanctis MC, Jaumann R, Konopliv AS, Preusker F, Asmar SW, Park RS, Gaskell R, Keller HU, Mottola S, Roatsch T, Scully JE, Smith DE, Tricarico P, Toplis MJ, Christensen UR, Feldman WC, Lawrence DJ, McCoy TJ, Prettyman TH, Reedy RC, Sykes ME, Titus TN. Russell CT, et al. Science. 2012 May 11;336(6082):684-6. doi: 10.1126/science.1219381. Science. 2012. PMID: 22582253
The Dawn spacecraft targeted 4 Vesta, believed to be a remnant intact protoplanet from the earliest epoch of solar system formation, based on analyses of howardite-eucrite-diogenite (HED) meteorites that indicate a differentiated parent body. ...

Elemental composition of lunar surface material.
Smales AA, Mapper D, Webb MS, Webster RK, Wilson JD. Smales AA, et al. Science. 1970 Jan 30;167(3918):509-12. doi: 10.1126/science.167.3918.509. Science. 1970. PMID: 17781474
Similarities and differences exist between lunar material, the eucritic achondrites, and the augite achondrite Angra dos Reis, the analysis of which is also reported....

Mineralogy and petrography of lunar samples.
Mason B, Fredriksson K, Henderson EP, Jarosewich E, Melson WG, Towe KM, White JS Jr. Mason B, et al. Science. 1970 Jan 30;167(3918):656-9. doi: 10.1126/science.167.3918.656. Science. 1970. PMID: 17781534
Except for their high ilmenite content, the lunar rocks resemble the calcium-rich achondritic meteorites (eucrites and howardites) in composition and structure. Evidence of a meteoritic increment in the lunar soil is provided by the presence of nickel-iron particles in gla …

The mineralogy of Vesta, based on data obtained by the Dawn spacecraft's visible and infrared spectrometer, is consistent with howardite-eucrite-diogenite meteorites. There are considerable regional and local variations across the asteroid: Spectrally distinct regions incl …

Gross similarities between euctites and Apollo 11 volcanic rocks indiacate similar evolutionary environments, but detailed mineralogical differences suggest either separate origins or if eucrites are lunar, chemical inhomogeneities on the lunar surface....

Asteroid 4 Vesta seems to be a major intact protoplanet, with a surface composition similar to that of the HED (howardite-eucrite-diogenite) meteorites. The southern hemisphere is dominated by a giant impact scar, but previous impact models have failed to reproduce the obs …
