Meteoritical Bulletin 111 contains the 3094 meteorites approved by Nomenclature Committee of Society in 2022. It includes 11 falls (Antonin, Botohilitano, Cranfield, Golden, Great Salt Lake, Longde, Msied, Ponggo, Qiquanhu, Tiglit, Traspena), with 2533 ordinary chondrites, 165 HED, 123 carbonaceous chondrites (including 4 ungrouped), 82 lunar meteorites, 28 Rumuruti 27 iron 23 ureilites, 22 mes...

Introduction: Enstatite chondrites have a particular minera-logical composition which consists of silicates, sulfide, metal as major phases. But, were the chondrules of EH and EL chondrites originated from the genetic context? In order to answer to this question we have started to investigate on mesostasis chemical composition of chondrules in three thin sections: one from EET90299-EL3 chondrit...

Abstract The South Banda back-arc basin is a morphotectonic environment that part of the Basin, characterized by flat morphology with depths ranging from 5000m to 6000m. purpose this paper analyze and relate morphometric aspects Quaternary seabed sediment deposits deposited in an active tectonic Sea area, including information on type its distribution as well relation volcanic hosted-massive su...

(S) from (E). d) The (A) body cannot be the parent asteroid of(S) because most (A) contain abundant diopside and have negative Eu anomalies, and impact melts of (A) would not crystallize pure opx nor would they have + E anomalies. Thus, (S) probably formed on a fourth enstatite asteroid. e) (S) experienced a 3 stage cooling history. Stage 1, quench: Hundreds 0 /hr of (S) melt from ~ 1580 oc to ...

Ureilites are ultramafic achondrites that exhibit heterogeneity in mg# and oxygen isotope ratios between different meteorites. Polymict ureilites represent near-surface material of the ureilite parent asteroid(s). Electron microprobe analyses of >500 olivine and pyroxene clasts in several polymict ureilites reveal a statistically identical range of compositions to that shown by unbrecciated ure...

CP micrometeorites are highly porous and fragile interplanetary dust particles (IDP' s) that have chondritic elemental abundances. Among the mineral species found within these particles are pure enstatite crystals, which are unique among the micron-sized constituents of CP IDP' s in that they are euhedral. They exhibit at least three distinct forms, henceforth referred to as rods, ribbons and p...
