The Qingzhen reaction, a fine‐grained mineral assemblage associated with djerfisherite in some EH3 chondrites: Alteration on the EH parent body

Meteoritics &Planetary Science, EarlyView.
Abstract Enstatite chondrites formed under extremely reducing conditions in the protoplanetary disk. They are derived from two or more parent bodies, EH and EL, and both EH and EL groups contain petrologic type 3–6 samples. The rare lithophile‐ and halogen‐bearing sulfide, djerfisherite, occurs in low abundance in enstatite chondrites, most frequently ...

Textural and geochemical diversity of impact melt rock clasts in Apollo 16 sample 67015: Implications for the provenance of impact ejecta in the lunar highlands

Meteoritics &Planetary Science, EarlyView.
Abstract Apollo sample 67015 has been classified as a fragmental breccia comprised of highlands‐type clasts and is proposed to be the most complex Apollo 16 sample. 67015 is dominated by impact melt rock clasts that display a variety of textures, which have been previously interpreted to be indicative of multiple impact events.

Description and modeling of the Jiddat al Harasis 091 L5 strewn field

Meteoritics &Planetary Science, EarlyView.
Abstract With a size of 51.2 × 7.2 km, the 10.9 ± 1.7 ka old Jiddat al Harasis 091 L5 chondrite strewn field is the largest known in Oman. It consists of more than 700 meteorites with a total mass of >4.5 tons from which the largest six stones of >100 kg to 1.5 tons make up two thirds of the total mass.

Modeling enstatite chondrites: Reduced rocks with a pinch of oxidized material (affected by varying H2O(g)) derived from planetesimals shocked during the epoch of giant–planet migration

Meteoritics &Planetary Science, EarlyView.
Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

Davisite, CaScAlSiO_6, a new pyroxene from the Allende meteorite [PDF]

, 2009
Davisite, ideally CaScAlSiO_6, is a new member of the Ca clinopyroxene group, where Sc^(3+) is dominant in the M1 site. It occurs as micro-sized crystals along with perovskite and spinel in an ultra-refractory inclusion from the Allende meteorite.
